Answer by kubi for Subclassing UIButton to handle clicks

I think there are better solutions to this problem than what you've proposed, but to answer your question directly: A subclass of UIButton observes touch events the same way that everyone else observes touch events.

// In your UIButton subclass- (instancetype)initWithFrame:(CGRect)frame {    self = [super buttonWithType:UIButtonTypeCustom];    if (self) {        [self addTarget:self action:@selector(didTouchButton) forControlEvents:UIControlEventTouchUpInside];    }    return self;}- (void)didTouchButton {    // do whatever you need to do here}

Important note: you can't use [UIButton buttonWithType:] to create your button, you've got to use init or initWithFrame:. Even though UIButton has the convenience initializer, initWithFrame: is still the designated initializer.
