My problem is about tap detection.

I have a uiviewcontroller and there are some controls on uiview (labels, buttons, tableview, imageview, etc..)

When I tap the uibutton I display a small uiview (200x150), if the user taps the uibuttons in smallview I hide the smallview.

But I can't hide the uiview if the user taps the background.
I tried this code..

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
    //NSLog(@"Touches began.");
    [self hideShareView];
}

It doesn't work if I tap the another button in the uiviewcontrols view.

I just want my uiviewcontrol's uiview to react first.
I think its about firstResponder but I dont know how to set it first.

edit: i want it to work like a uiPopover in ipad.
