ibaction

So I have a button that is connected to a IBAction. When I press the button I want to hide the tab bar in my iOS app with a animation.

It's like in the delegate functions where you have the control passed in to the

The problem that i'm facing is that i don't get any actions for the Rounded Rect Button which is inside the UIView (B). The singleTap gesture recognizer captures/overrides the button's Touch Up Inside event. How can i make it work?
