STTweetLabel

A custom UILabel view controller for iOS with certain words tappable like Twitter (#Hashtag, @People and http://www.link.com/page)

Documentation

You need only 2 files:

STTweetLabel.h
STTweetLabel.m

You can change the fonts and colors for the different words (#Hashtag/@People AND http://link.com) via the STTweetLabel attributes.

Demo

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

Example Usage

    STTweetLabel *tweetLabel = [[STTweetLabel alloc] initWithFrame:CGRectMake(20.0, 60.0, 280.0, 200.0)];
    
    [tweetLabel setFont:[UIFont fontWithName:@"HelveticaNeue" size:17.0]];
    [tweetLabel setTextColor:[UIColor blackColor]];
    [tweetLabel setText:@"Hi. This is a new tool for @you! Developed by->@SebThiebaud for #iPhone #ObjC... ;-) My GitHub page: https://t.co/pQXDoiYA"];
    [self.view addSubview:tweetLabel];

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

    STLinkCallbackBlock callbackBlock = ^(STLinkActionType actionType, NSString *link) {
	        
        NSString *displayString = NULL;
        
        // determine what the user clicked on
        switch (actionType) {
                
            // if the user clicked on an account (@_max_k)    
            case STLinkActionTypeAccount:
                displayString = [NSString stringWithFormat:@"Twitter account:\n%@", link];
                break;
            
            // if the user clicked on a hashtag (#thisisreallycool)
            case STLinkActionTypeHashtag:
                displayString = [NSString stringWithFormat:@"Twitter hashtag:\n%@", link];
                break;
            
            // if the user clicked on a website (http://github.com/SebastienThiebaud)
            case STLinkActionTypeWebsite:
                displayString = [NSString stringWithFormat:@"Website:\n%@", link];
                break;
        }
        
        [_displayLabel setText:displayString];
        
    };

Once you have added those few lines of code (depending on what you want to do when the user taps on something), make sure to tell your instance of STTweetLabel to call this block:

    [_tweetLabel setCallbackBlock:callbackBlock];
