handling same touch event with multiple control (parent and child)

Question

I need to handle a touch event on my custom uiviewcotroller. I have a sub controller within the view that already handle touch event (it's a plot that handle zooming and scrolling). I want to make a tabbar disappear when I tap the screen once. Actually it only works (even tought the tabbar doesn fade away but simply is no visible) in the areas in which the subcontrol is not present but I need it to work everywhere still handling the subcontrol events.

Answer 1

Try to set userInteractionEnabled = NO in subcontrol view.

UPD: Try to add transparent button to subcontrol.

Answer 2

Make sure you're calling the superclass's event handler method in your event handler method to continue propagation of the event up the responder chain.

Also make sure the subcontrol's exclusiveTouch property is set to NO.

You might want to have a look at the event handling documentation.
