UIButton block equivalent to addTarget:action:forControlEvents: method?
I just implemented this. It work’s like a charm! And it wasn’t even hard. typedef void (^ActionBlock)(); @interface UIBlockButton : UIButton { ActionBlock _actionBlock; } -(void) handleControlEvent:(UIControlEvents)event withBlock:(ActionBlock) action; @end @implementation UIBlockButton -(void) handleControlEvent:(UIControlEvents)event withBlock:(ActionBlock) action { _actionBlock = action; [self addTarget:self action:@selector(callActionBlock:) forControlEvents:event]; } -(void) callActionBlock:(id)sender{ _actionBlock(); } @end

You should modify your code to look like this: NSMutableParagraphStyle *style = [[NSParagraphStyle defaultParagraphStyle] mutableCopy]; [style setAlignment:NSTextAlignmentCenter]; [style setLineBreakMode:NSLineBreakByWordWrapping]; UIFont *font1 = [UIFont fontWithName:@”HelveticaNeue-Medium” size:20.0f]; UIFont *font2 = [UIFont fontWithName:@”HelveticaNeue-Light” size:20.0f]; NSDictionary … Read more

Adding a closure as target to a UIButton
