We have had an app rejected because of the following private API calls:

UITouch.locationInWindow
UITouch.phase
UITouch.previousLocationInWindow
UITouch.tapCount
UITouch.timestamp
UITouch.touchFlags
UITouch.view
UITouch.window

I have found them in UIViewAdditions.m.

More a comment on the documentation than a real issue: I was following the directions for including three20 in my XCode project to the letter and I kept getting a build error: "error: Three20/
Three20.h: No such file or directory"

The solution I found is that you have to add the relative path to "three20/src" to the Header Search Paths in both the project settings AND the target settings for the target you're building. Changing the instructions on the main page to reflect this might save people a lot of headaches...

I don't have the error in front of me, but I've been bitten by this one recently.

NSObjectAdditions.h declares a property named URLValue. Some libraries (i.e. ObjectiveResource) will inspect a class for its properties and assume them all to be KVC-compliant, then at certain points at runtime, will call set* on all properties, including setURLValue:, which NSObjectAdditions.m neither synthesizes nor implements. This blows up and kills the thread.

The workaround I've been using is to simply implement a do-nothing setURLValue method in each model class that's going to be introspected in this way. It might even be worth adding to Three20 itself with a slightly less confusing basic implementation, like this:

- (void) setURLValue:(NSString*)urlValue { 
  /* Best not to call this, it's just here to maintain KVC-compliance */ 
  [[TTNavigator navigator].URLMap from:self toURL:urlValue];
}

(In my case I actually kept the implementation empty, because I didn't want some arbitrary library updating my URLMap because it had picked it up during runtime introspection.)

The is a memory Leak in TTViewController.m Line 183.

Change :

NSMutableDictionary* state = [[NSMutableDictionary alloc] init];

To :

NSMutableDictionary* state = [[[NSMutableDictionary alloc] init] autorelease];

When there is only one TTLauncherItem in the launcherview, the application crashes when the user initiates editing mode by tapping & holding the item.

Renaming the readme, will show it on the GitHub page for the repo again.

It seems it is impossible to build against iPhone 2.x device at the current moment?

Are you planning to keep support for versions < 3.0 or not at all?

Thanks!

I am trying to reload the thumbs from inside as setting a new photoSource array .I succeeded to do it by custom methods but the thumbnails are being actualized only when they go outside of the screen and return back. Is there any global method I can use to refresh this 'screen cache'?

Per this documentation:
http://developer.apple.com/documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmObjectOwnership.html#//apple_ref/doc/uid/20000043-SW2

UIColorAddition's [UIColor copyWithAlpha:] should return an object that has a retain count of 1 since it begins with "copy." Since it uses [UIColor colorWithRed:green:blue:alpha:], it's already been autoreleased and has an effective retain count of 0.

At the same time, [UIColor addHue] should not retain its returned color, as its name does not start with copy or new. (Be careful: this is used by toolbarButtonColorWithTintColor.)

in src/Three20/TTGlobal.h

import "Three20/UITabBArControllerAdditions.h"

should be

import "Three20/UITabBarControllerAdditions.h"

Causes problems if you use the case-sensitive filesystem, otherwise you won't notice

To repeat add _scrollView.zoomEnabled = NO; below line 23 in ScrollViewTestController.m so the code segment looks as follows.

_scrollView = [[TTScrollView alloc] initWithFrame:self.view.bounds];
_scrollView.dataSource = self;
_scrollView.backgroundColor = [UIColor whiteColor];
_scrollView.zoomEnabled = NO;
[self.view addSubview:_scrollView];

After making this change, the scroll view demo no longer snaps to page boundaries.

It seems like the following change from SHA: 7cc9f75 is the likely cause:
- if (!stayPulled && (self.pinched || (touchCount == 0 && self.pulled))) { + if ((self.pinched || (touchCount == 0 && self.pulled)) && zoomEnabled) {

Could it be possible to add methods for adding headers to TTURLRequest.
There is one or more forks out there for this but since i wouldnt want to fork off Three20 for this small addition.

TTTableViewController should respond to the setEditing:animated: message by telling its tableView to toggle editing mode (show delete icons, etc.). This is part of the functionality that UITableViewController automatically provides with respect to managing a table view, but since TTTableViewController is not a subclass of UITableViewController, it does not inherit this behavior.

For your convenience, here is a simple implementation.

- (void)setEditing:(BOOL)editing animated:(BOOL)animated
{
    [super setEditing:editing animated:animated];
    [self.tableView setEditing:editing animated:animated];
}

When the user is in the full-screen photo view, if he is looking at the last photo in the loaded set, but there are more photos available in the photo source, when he taps the "next" arrow button, it advances to a placeholder loading screen but the image never loads.

I looked into it with the debugger and found that when nextAction is triggered, the photo source never receives the load:more: message, even though you would expect that it would receive such a message, specifically where "more"=YES.

You can easily recreate this bug in the "photo example" part of my TTRemoteExamples project.

As soon as a photo is fully under the (transparent) title bar, it is no longer drawn. This is obvious when scrolling with PhotoTest2Controller, or with PhotoTest1Controller after touching "Show All". I would prefer images continue to be drawn, but turning off translucency would also fix this.

This can be seen on the TTCatalog sample app, and in our own project.

Steps to reproduce:
1. Start TTCatalog in the simulator
2. Click any demo item to go to another view
3. Attempt to return to the main view - it will be empty.

Is the above behaviour the result of the samples taking a shortcut and not dealing with the low memory event properly? How is this supposed to be worked around?

If a page is still "Loading" the action sheet's "Open in Safari" command has no action. It only works if the page finishes loading or the user stops the load via the "X" tab bar item.

In TTImageItem you can set the imageStyle property. In TTTableImageItemCell this property is accessed and applied to the _iconView. There is one issue I spotted immediately. The block of code in TTTableImageItemCell where all this is setup is below.

  TTImageStyle* style = [item.imageStyle firstStyleOfClass:[TTImageStyle class]];
  if (style) {
    _iconView.contentMode = style.contentMode;
    _iconView.clipsToBounds = YES;
    _iconView.backgroundColor = [UIColor clearColor];
    if (style.size.width) {
      iconWidth = style.size.width;
    }
    if (style.size.height) {
      iconWidth = style.size.height;
    }
  }

When you're checking style.size.height there is a mistake where you're setting iconWidth again instead of iconHeight.

The bigger issue is that no more of the imageStyle is actually used. I tried setting breakpoints in TTImageView and for reasons unknown to me none of the draw routines are ever called so the style is never applied. It's possible I'm missing something here, but I don't immediately see what it is.

With the TTAppMapDemo, the MenuController showMenu: method only gets nil as a parameter for all the tt://menu/1, tt://menu/2, etc. URLs.

I've noticed the same thing in my app.

The only way I've been able to get any information to the selector in the pattern is to use query URLs (like [appMap addURL:@"tt://order?waitress=(orderWithWaitress)" modal:[ContentController class] selector:@selector(orderWithWaitress:params:)];) and ignoring what is in the waitress parameter (it's always nil).

In TTWebController in webViewDidFinishLoad: it should be
backButton.enabled = [webView canGoBack]; otherwise it's not working correctly after you click the first link.
Or am I wrong?

repro:
modify the sample app PhotoTest1Controller.m so that:

[TTURLCache sharedCache].disableDiskCache = YES;
[TTURLCache sharedCache].disableImageCache = YES;
[TTURLRequestQueue mainQueue].maxContentLength = 0;

This makes it so that we can easily repeatdly reproduce this bug without interference from the cache. also need to change the max content length so that we can download large files. and do a request for a large image like:

[[[MockPhoto alloc]
  initWithURL:@"http://www.fsf.org/blogs/community/5-reasons-to-avoid-iphone-3g/iphone3g-original.png"
  smallURL:@"http://farm4.static.flickr.com/3444/3223645618_f5e2fa7fea_t.jpg"
  size:CGSizeMake(320, 480)
  caption:@"These are the wood tiles that we had installed after the accident."] autorelease],

So if everything works fine, you should see the funky pink iphone image. Now go back, and load the image again. This time quickly cancel the request by pressing back. If you do it correctly, you will get an instant crash in:
- (void)imageViewDidFailLoadWithError:(NSError*)error { if (self.url == [_photo urlForVersion:TTPhotoVersionLarge]) {

the issue here is that photo has already been released (and indireclty been dealloc). This happened in TTPhtoView:dealloc
[photo release] Hence we are trying to derefrence freed memory, big problem.

I fixed this by simply making sure that after the release, I do:
_photo = nil;

in general you should always nil out your member variables after you release them. I have a handy macro:

define SAFE_RELEASE(obj) do {\

[obj release];\ obj = nil;<br/> } while(0)

looking at all your deallocs, I strongly suggest you nil things out, especially because of the intensive use of delgates (mostly strong reference ones)

Has anyone else experienced this problem?

Here are a couple examples. This one uses a method defined in UIColorAdditions.h

UIColor* highlight = [color multiplyHue:0 saturation:0 value:1.2];

This one uses a method defined in NSObjectAdditions.h

[queue performSelector:@selector(loader:didLoadResponse:data:) withObject:self withObject:response withObject:_responseData];

I don't see anyone else mentioning this issue, so perhaps there's something strange with my setup.

Please help if you know the answer to this one. -Steve

Is there a way to position the caption text at a specific place on the screen? And/or add line breaks to the captions? And left/right align rather than center?

I downloaded the Thrre20 Library and tried the Sample Code, but I only get an error inside the Console.

The Code compiles fine, but direkt after the start the App stops with only this message inside the console:

I'm using Three20 as a dependency in another project and I got the following exception when creating a TTButton from a style I define in my own style sheet. It looks like something is not working quite right with the UIColor additions you created on 3.0 devices. Other relevant bits of data:

When thumbnail images are loaded off the local documents directory, scrolling is "choppy." As cells reappear on screen the re-drawing appears to stutter the scrolling.

The stutter is not nearly as pronounced on the catalog example. It feels like the loading method is written with the loading of remote images in mind. When the catalog example has cells off screen, the cells are re-drawn and then the thumb is filled in as its retrieved. The short time involved re-drawing of both the cell and the thumb seems to be the cause of the stutter with local images.

While Clang, the open source Objective-C static analyzer does happen to flag quite a few false positives, and it likely misses plenty of bugs, it does sometimes catch things you've forgotten about.

For instance, in NSStringAdditions:

It suggests renaming createSpotlightMask:origin:radius: in TTSearchlightLabel to match guidelines, e.g. newSpotlightMask:

Object allocated on line 64 is returned from a method whose name ('createSpotlightMask:origin:radius:') does not contain 'copy' or otherwise starts with 'new' or 'alloc'. This violates the naming convention rules given in the Memory Management Guide for Cocoa (object leaked)

In TTThumbsViewController:

It also reports two initializations that are never used again in TShape.

Here, because copyWithAlpha in UIColorAdditions begins with "copy", it expects a retain count of 1 for the returned object:

I'm not sure what's going on here (in TTURLRequestQueue), as I haven't studied NSError much at all yet myself. I imagine you're trying to override the error, which might make sense except if the error pointer is null, as Clang so kindly points out: (it also highlights line 329 separately)

Did I mention Clang's great at worst case scenario planning? (TTThumbsTableViewCell)

Anyway, that's it for Clang. You can download it at http://clang.llvm.org/StaticAnalysis.html and for anyone having trouble running it, make sure xcodebuild works at the command line - it doesn't use the active configuration the Build buttons use, but instead look carefully in Project Settings for a command line mode drop-down (I think).

Thanks for the great work, Joe, I really appreciate it, and hope I can contribute more at some point too. :-)

So I have a TTMessageController and I'm calling setBody: on it. The text is applied fine, but when it's a lot of text (say, 800px worth), this method gets called and results in a very tall text editor that's obscured beneath the keyboard and also not scrollable (it just jitters when I try to scroll on 2.2.1):

• (BOOL)textEditor:(TTTextEditor*)textEditor shouldResizeBy:(CGFloat)height

Going to start brainstorming how I'd patch this.

Just noticed this checkin by fly1028 to fix memory leaks in TTPhotoViewController. Making an issue for it so it gets some review and testing.

http://github.com/fly1028/three20/commit/d49beca5a44a6f55c79b090db88aece6ed856056

The only trivial way I can think of to change the appearance of an anchor tag in styled text right now is to override linkText: in the stylesheet, but how should/can one have multiple link styles currently?

I'm currently using a span and trapping its touch events to treat it like a a link. Groups email: http://groups.google.com/group/three20/browse_thread/thread/54939515d2516857

If you create a tab strip:

_tabBar1 = [[TTTabStrip alloc] initWithFrame:CGRectMake(0, 0, 320, 41)];
_tabBar1.tabItems = [NSArray arrayWithObjects:
[[[TTTabItem alloc] initWithTitle:@"Item 1"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 2"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 3"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 4"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 5"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 6"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 7"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 8"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 9"] autorelease],
[[[TTTabItem alloc] initWithTitle:@"Item 10"] autorelease],

and set a table's header view to be the tab strip:

self.tableView.tableHeaderView = _tabBar1;

The TTTabStrip will display just fine and you can selected the (visible) tabs, but you can't scroll the strip from side to side. Works fine in a regular view...

i get these build errors when building for a 3.0 beta 5 device

also building for the 3.0 beta 5 simulator, the image display doesnt seem to work properly. the image no longer fills the screen, and leaves white space below the image. Once you click on the image, its not possible to get the navigation bar back into view

If building Three20 under the current beta SDK, the underlaps the status bar and Navigation bar leaving whitespace at the bottom of the screen equivalent in height to the status bar plus the navigation bar height. The photo jumps around when the tool bar/navigation bar appears and reappears on screen.

Some applications do not need to register a custom, internal url scheme with the NavigationCenter. However, they may assume that Three20 knows to handle the HTTP scheme automatically by launching MobileSafari.

If they do not set the urlSchemes property, http links in TTStyledText will not load (the shouldLoadExternalURL: message will never fire, even if the delegate is hooked up and implements the method).

The workaround for such applications is to set urlSchemes to an empty array. For example:

TTNavigationCenter* nav = [TTNavigationCenter defaultCenter]; 
nav.mainViewController = myTabBarController; 
nav.delegate = self; 
nav.urlSchemes = [NSArray array];  

When I load a TTPhotoViewController subclass in a UINavigation controller it spawns a photo search request and sits there for a few seconds with no photos while it waits for the request to complete. If I hit the back button right away before any of the images load, deallocating the TTPhotoViewController causes a crash in TTPhotoView:imageViewDidFailLoadWithError presumably because _photo doesn't exist yet.

The crash is at the line 199 of TTPhotoView.m
if (self.url == [_photo urlForVersion:TTPhotoVersionLarge]) {

Looking up the value of photo, gdb says "struct objc_object* photo 0x25bb00 Invalid"

No idea what Invalid means here or how to test for it.

Yesterday's checkin uses the method initWithDateFormat:allowNaturalLanguage, but iPhoneOS doesn't have this method, only MacOS X. This means that I can compile for the simulator with no problems but when I compile for the device I get a warning when linking NSDateAdditions.o

After using TTPhotoViewController to view a lot of Flickr images I've seen a significant number that won't load because of issues with content length. Instead, a grainy, enlarged thumbnail image is displayed along with a caption that says 'this photo is not available. The square thumbnail images always seem to load but sometimes there's a problem with flickr's medium images.

from system.log
Connecting to http://farm3.static.flickr.com/2353/3536799600_47580f0bdc.jpg
MAX CONTENT LENGTH EXCEEDED (225821) http://farm3.static.flickr.com/2353/3536799600_47580f0bdc.jpg

Here's the code that generates the log message.
http://github.com/joehewitt/three20/blob/ccadfb1dac61a0d9eda31af8fe93e4a38f9c7375/src/TTURLRequestQueue.m#L169

To test this, add the following code to viewDidLoad in PhotoTest1Controller.com in the TTCatalog test app.

[[[MockPhoto alloc] initWithURL:@"http://farm3.static.flickr.com/2353/3536799600_47580f0bdc.jpg" smallURL:@"http://farm3.static.flickr.com/2353/3536799600_47580f0bdc_s.jpg" size:CGSizeMake(500, 375) caption:@"heart of stone"] autorelease],

The generatePostBody method does not format the multipart/form-data request in a format that Rails can parse.

Rails is returning the error:
Status: 500 Internal Server Error
bad content body

I've fixed this in my fork:
http://github.com/daikini/three20/commit/076c731086e7e3f23aa9a9c13c9b8435de31f4e0

I've tested the fix against PHP, Rails and Merb and they all can parse the new format correctly.

Just observed something while testing a message view. Say I have a table view layout (really long content) about 3000px tall, end-to-end.

Then I call up a modal message controller and send and dismiss the modal.

I observe two peculiar things back in my original view:
1. That 3000px table view appears fine until you get to the bottom, and then it's about 300px too short (meaning you can't scroll to see the last 2/3 of the screen. I'm pretty sure this length = the height of the message controller's editable fields.

1. Table states (i.e. "Loading..." have the opposite effect, as when i invoke one of those, it visually is pushed down from the top by roughly 300px.

Anything jump out at you? Otherwise I'll start looking at how the message controller is affecting the layout of the table view.

Hi

If you apply, a shape style to a TTImageView it will not work properly:

TTImageView *iv = [[[TTImageView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)] autorelease];
iv.style = [TTShapeStyle styleWithShape:[TTRoundedRectangleShape shapeWithRadius:10] next:nil];
iv.contentMode = UIViewContentModeScaleToFill;
iv.image = [UIImage imageNamed:@"iTunesArtwork.png"];
[self.view addSubview:iv];

The image will appear as expected, but with no round corners. If I apply it, to a TTView, without a TTImageView in it, it works perfectly.

I've read the drawInRect method in TTView and I'm not seeing any mistake. It should work...

Anyone knows how to solve this?

Cya :)

Sorry if this is inappropriate - I'm new here. Wondering if anyone else has encountered this? Pulled git clone today, Monday, 04/27/09, and added to an otherwise working project. Build for Simulator 3.0 Debug fails with error:
".objc_class_name_CALayer", referenced from: .objc_class_name_TTImageLayer in libThree20.a(TTImageView.o) symbol(s) not found

Really awesome to make this library available. Thanks!

The following commit - http://github.com/elliotb/three20/commit/77bbe0078f519933866226bce8cb1068c038b5d1#diff-7
breaks the padding for TTStyledTextFieldCells, as their content is now rendered up to all the edges of the cell due to the removal of the line:

_label.contentInset = UIEdgeInsetsMake(kVPadding, kHPadding, kVPadding, kHPadding);

This is the case for tables with the grouped style. The plain style seems unaffected in TTCatalog.

This is in TTGlobal.h:

@property(nonatomic,readonly) NSString* viewURL;

but it is never synthesized.....

TTActivityLabel defaults the centered and centeredToScreen properties to YES and the instance is put in the center of the screen when in portrait orientation. When switching to landscape orientation the activity label is moved down and to the left.

I have a table with TTIconTableFields that load images from a web url. The images scale to approximately 175 pixels high, but initially the table does not account for this an simply makes each row the size necessary to display the included text. If you scroll around a bit, some of the cells will sometimes resize and get bigger to display the image properly, but usually the images just overlap into neighbooring cells. The problem is even worse with ImageTableFields, as those have inconsistent heights AND inconsistent image sizes (sometimes the images are shrunk to tiny icons, and sometimes they expand to bigger sizes).

I have a subclass of TTTableViewController with a TTTabBar subview. Instead of making the tab bar the table header, I made it a separate view so it would not scroll with the table, and made the table's frame height smaller to accommodate this. However, now when it displays an error view, the error cell height is too large. It doesn't seem to be taking into account the height of the table view it is being displayed in.

The included ObjC categories are not getting linked when building for the device target (ie., arm) on the latest "beta" SDKs. Adding -all_load, in addition to -ObjC to OTHER_LDFLAGS seems to fix the problem. I have filed this: rdar://6806626

It would be useful if TTImageView could scale images in a similar way to UIImageView. Particularly if it had support for constraining/scaling the image to the view's size while keeping the aspect ratio of the image the same as the original.

This was posted on the google group a while ago, but I'm getting this bug as well:

As the poster said, you can reproduce it in TTCatalog by typing 'z'.

TTStyledText should support line breaks, and parse HTML tags that would result in line breaks.
