Passing action to one uiview to another in IOS

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.

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.
