Overview

DCOAboutWindow is a replacement for the standard About dialog.

It adds the option to open acknowledgments and visit the website by clicking a button.

DCOAboutWindow in action DCOAboutWindow in Dark Mode

Showing acknowledgments

You can point to and maintain a custom Acknowledgments.rtf file, or you can use a script like Acknowledge to generate it for you.

Setup

Via cocoapods

Add the following line to your Podfile:

pod 'DCOAboutWindow'

Then run pod install and you're set.

Via Carthage

Add the following to your Cartfile:

github "DangerCove/DCOAboutWindow"
github "DangerCove/DCOTransparentScroller"

Then run carthage update and you're set.

Manually

Clone this repo and add files from DCOAboutWindow to your project.

The project relies on DCOTransparentScroller, so include that too.

Usage

I've made a sample project that accompanies this tiny guide.

Import DCOAboutWindowController:

#import <DCOAboutWindow/DCOAboutWindowController.h>

Instantiate DCOAboutWindow:

// Note: make sure self.aboutWindowController is retained
self.aboutWindowController = [[DCOAboutWindowController alloc] init];

Create an IBAction to display the window:

- (IBAction)showAboutWindow:(id)sender {
  [self.aboutWindowController showWindow:nil];
}

Hook it up to the 'About [app name]' menu item or a button.

You can change values by setting properties on DCOAboutWindowController:

/**
 *  The application name.
 *  Default: CFBundleName
 */
@property (copy) NSString *appName;

/**
 *  The application version.
 *  Default: "Version %@ (Build %@)", CFBundleVersion, CFBundleShortVersionString
 */
@property (copy) NSString *appVersion;

/**
 *  The copyright line.
 *  Default: NSHumanReadableCopyright
 */
@property (copy) NSString *appCopyright;

/**
 *  The credits.
 *  Default: [[NSBundle mainBundle] pathForResource:@"Credits" ofType:@"rtf"];
 */
@property (copy) NSAttributedString *appCredits;

/**
 *  The URL pointing to the app's website.
 *  Default: none
 */
@property (strong) NSURL *appWebsiteURL;

/**
 *  The path to the file that contains the acknowledgments.
 *  Default: [[NSBundle mainBundle] pathForResource:@"Acknowledgments" ofType:@"rtf"];
 */
@property (nonatomic, copy) NSString *acknowledgmentsPath;

/**
 *  If set to YES acknowledgments are shown in a text view, inside the window. Otherwise an external editor is launched.
 *  Default: NO;
 */
@property (assign) BOOL useTextViewForAcknowledgments;

Pre-processing (for Dark Mode)

You can pre-process the NSAttributedString containing the app credits using a delegate. This is great for making the about window play nice with Mojave's Dark Mode. Here's how it works:

// Conform to the DCOStringPreprocessingProtocol
@interface DCDAppDelegate() <DCOStringPreprocessingProtocol>

self.aboutWindowController = [[DCOAboutWindowController alloc] init];
// Set the delegate
self.aboutWindowController.delegate = self;

#pragma mark - DCOStringPreprocessingProtocol

- (NSAttributedString *)preprocessAppCredits:(NSAttributedString *)appCredits {
    NSMutableAttributedString *mutableCredits = [appCredits mutableCopy];
    
    NSDictionary *attributes = @{ NSForegroundColorAttributeName : [NSColor textColor] };
    [mutableCredits addAttributes:attributes range:NSMakeRange(0, mutableCredits.length)];
    
    return [mutableCredits copy];
}

// Optionally pre-process the acknowledgments as well
- (NSAttributedString *)preprocessAppAcknowledgments:(NSAttributedString *)appAcknowledgments {
    NSMutableAttributedString *mutableAcknowledgments = [appAcknowledgments mutableCopy];
    
    NSDictionary *attributes = @{ NSForegroundColorAttributeName : [NSColor textColor] };
    [mutableAcknowledgments addAttributes:attributes range:NSMakeRange(0, mutableCredits.length)];
    
    return [mutableAcknowledgments copy];
}

Thanks to @balthisar for adding this.

Localization

Add the following lines to your Localizable.string to change these values, or localize them.

/* Version %@ (Build %@), displayed in the about window */
"Version %@ (Build %@)" = "v%@ (%@)";

/* Caption on the 'Visit the %@ Website' button in the about window */
"Visit the %@ Website" = "Visit %@'s Website";

/* Caption of the 'Acknowledgments' button in the about window */
"Acknowledgments" = "Acknowledgments";

/* Caption of the 'Credits' button in the about window when acknowledgments are shown when useTextViewForAcknowledgments is YES. */
"Credits" = "Credits";

Contributions and things to add

Be creative. DCOAboutWindow should be a flexible, easy to use way to make the About Window for your app look pretty. Make sure your changes don't break existing functionality without good reason.

Changelog

v0.4.0

  • Fix typo in preprocessor delegate method name.
  • Implement alternative for deprecation.

v0.3.1

  • Make version string selectable.

v0.3.0

v0.2.0

  • Optionally display acknowledgments inside the window, instead of through an external editor.

Set useTextViewForAcknowledgments to YES to enable this feature.

  • Improve Auto Layout constrains. The image view now remains the same width, while the text fields can become wider.

v0.1.0

  • Improved localization support
  • Improved auto-layout constraints to handle resizing better

You can toggle (off by default) resizing by setting the NSWindow's styleMask. Check out the example project to see how this works.

v0.0.2

  • Switched to using 'Acknowledgments' instead of 'Acknowledg_e_ments' to be more consistent and prevent incompatibility with Acknowledge. NOTE: Make sure you change the filename of your acknowledgments and any setters/getters.

v0.0.1

  • Initial release.
