A custom UILabel for iOS with certain words tappable like Twitter (#Hashtag, @Handle and links).

Please use CocoaPods and include STTweetLabel in your Podfile.

Important: STTweetLabel 3.0 is based on TextKit and is only compatible with iOS 7 and above.

Build and run the project STTweetLabelExample in Xcode to see STTweetLabel in action.

STTweetLabel *tweetLabel = [[STTweetLabel alloc] initWithFrame:CGRectMake(10.0, 60.0, 300.0, 160.0)];
[tweetLabel setText:@"Hi. This is a new tool for @you! Developed by @SebThiebaud for #iPhone #ObjC... and #iOS7 ;-) My GitHub page: https://t.co/pQXDoiYA"];
[self.view addSubview:tweetLabel];

Don't forget to implement the detectionBlock. Without implementing this block, you won't be able to detect if somebody has clicked on the hashtag, handle or even a link. Blocks are easy. All you need to do is add a few lines of code:

[tweetLabel setDetectionBlock:^(STTweetHotWord hotWord, NSString *string, NSString *protocol, NSRange range) {
    // Do something
}];

• NSString *text: The text to display.
• NSArray *validProtocols: All valid protocols for link (by default: @[@"http", @"https"]).
• BOOL leftToRight: Writing direction (by default: YES).
• BOOL textSelectable: Allows the user to select the text (by default: YES).
• UIColor *selectionColor: If BOOL textSelectable is enabled, it's the color of the selection's background (by default: [UIColor colorWithWhite:0.9 alpha:1.0]).
• NSTextAlignment textAlignment: Text alignment (by default: NSTextAlignmentLeft).

The two following methods refresh the component. That means you should only set the attributes at the initialization of your STTweetLabel instance.

• -[STTweetLabel setAttributes:(NSDictionary *)attributes]: Dictionary with attributes for all text.
• -[STTweetLabel setAttributes:(NSDictionary *)attributes hotWord:(STTweetHotWord)hotWord]: Dictionary with attributes for specific STTweetHotWord.
• -[STTweetLabel suggestedFrameSizeToFitEntireStringConstraintedToWidth:(CGFloat)width: Returns the CGSize calculated for the text submitted.

Inspired by the original Twitter application.
