Question

I have created a UIView called ImageShowcase which has a UIScrollView and then i am adding UIButton inherited class call ImageShowcaseCell. Its working fine. One thing i am puzzled about is what is the best way to handle actions in a view controller where i have added ImageShowCase currently when i can handle UIControlEventTouchUpInside action in UIButton inherited class ImageShowcaseCell but i want to handle it in View Controller so that i can perform appropriate action.

What would be the best way to achieve this.

Answer 1

In your custom ImageShowcaseCell class, you can send the action up the responder chain and allow the view controller to handle it:

[[UIApplication sharedApplication] sendAction:@selector(someMethodOnMyViewController:) to:nil from:self forEvent:nil];

Alternatively you could possibly also use:

1. delegate pattern – set your view controller as a delegate for your ImageShowcaseCell.
2. create a block based method in your custom class to execute the block after a touch.
