DMPathBar

[](https://travis-ci.org/Daniele Margutti/DMPathBar)

DMPathBar is a Path Bar Cocoa control like the one used in Xcode to pick Targets or Finder in Yosemite (aka MacOS X 10.10) while browsing along a path.

I've made it to looks great in Yosemite but you can easily customize it for your needs.

As many other Yosemite controls, DMPathBar fully support animations for each available operation (add/set/remove/replace items) using a modern block style syntax.

A short introduction

To run the example project, clone the repo, and run pod install from your project.

Then you can create a new DMPathBar from IB by dragging a new custom view instance and set it to 'DMPathBar'. You can also create it programmatically:

NSImage *myIcon = ...;
NSString *myTitle = ...;
DMPathBarItem *titleItem = [DMPathBarItem itemWithTitle: myTitle icon: myIcon];

self.pathBar = [[DMPathBar alloc] initWithFrame:NSMakeRect(0.0f,0.0f,300.0f,25.0f)];
[self.pathBar setTitleItem: titleItem animated:NO completion:NULL];

Each path item of the tabbar is a DMPathBarItem. You can create new path bar with title&icon, only title or only icon (+itemWithTitle:icon:).

DMPathBarItem can also hold custom views too (using +itemWithCustomView:)

Actions

You can respond to the click event inside one of the path bar items by implementing the .action property defined as a block:

typedef NSMenu*(^DMPathBarAction)(NSInteger index,DMPathBarItem *item);

If you return an NSMenu instance your click on the item will open passed menu as contextual menu. If you return nil it's just a simple click.

That's an example:

   pathBar.action = ^NSMenu *(NSInteger idx,DMPathBarItem *item) {
   	NSLog(@"Tap on item %ld : %@",idx,item);
   	
   	if (idx == 0) {
   		// Click on the title item will show a menu
   		NSMenu *menu = [[NSMenu alloc] initWithTitle:@""];
   		[menu addItemWithTitle:@"Item 1" action:@selector(test:) keyEquivalent:@""];
   		[menu addItemWithTitle:@"Item 2" action:@selector(test:) keyEquivalent:@""];
   		return menu;
   	} else {
   		// Do something with other items
   		return nil;
   	}
   };
}

Set Title Item

This method add or replace the existing title of the pathbar:

DMPathBarItem *item = ...;
[self.pathBar setTitleItem: titleItem animated:NO completion:NULL];

Set Items

You can set more than one items at once by using -setItems:... methods. There are two setItems methods based upon the type of the animation you want to achieve. If you want a single set animation you can use:

NSArray *items = @[pathItem1,pathItem2...];
[self.pathBar setItems: items animated:YES inSequence:NO completion:NULL];

while if you want a single animation for each add you can pass YES to inSequence parameter.

Add Single Item

To add a new item at the end of the path bar use:

DMPathBarItem *item = ...;
[self.pathBar addItem: item animated:YES  completion:NULL];

Remove Items

To remove the last item:

DMPathBarItem *item = ...;
[self.pathBar removeItemAnimated:YES  completion:NULL];

to remove all items (see 'Set Items' paragraph to learn more about inSequence parameter):

DMPathBarItem *item = ...;
[self.pathBar removeAllItemsAnimated:YES inSequence:YES  completion:NULL];

Replace Existing Item

To replace an existing item in a path bar:

DMPathBarItem *newItem = ...;
[self.pathBar replaceItemAtIndex:0 with:newItem animated:YES  completion:NULL];

Accessory View

Finally you can set an optional NSView instance (called Accessory View) as complement of your path bar. You can position it both on left or right (see .accessoryPosition property):

MyViewClass *accView = ...;
[self.pathBar setAccessoryView:accView animated:YES  completion:NULL];

Requirements

It works with OS X 10.10. It also should work on 10.9 but I've not tested it.

Installation

DMPathBar is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "DMPathBar"
