UIButton inside a view that has a UITapGestureRecognizer
As a follow up to Casey's follow up to Kevin Ballard's answer:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
if ([touch.view isKindOfClass:[UIControl class]]) {
// we touched a button, slider, or other UIControl
return NO; // ignore the touch
}
return YES; // handle the touch
}
This basically makes all user input types of controls like buttons, sliders, etc. work
You can set your controller or view (whichever creates the gesture recognizer) as the delegate of the UITapGestureRecognizer
. Then in the delegate you can implement -gestureRecognizer:shouldReceiveTouch:
. In your implementation you can test if the touch belongs to your new subview, and if it does, instruct the gesture recognizer to ignore it. Something like the following:
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
// test if our control subview is on-screen
if (self.controlSubview.superview != nil) {
if ([touch.view isDescendantOfView:self.controlSubview]) {
// we touched our control surface
return NO; // ignore the touch
}
}
return YES; // handle the touch
}

You can also use
tapRecognizer.cancelsTouchesInView = NO;
Which prevents the tap recognizer to be the only one to catch all the taps
UPDATE - Michael mentioned the link to the documentation describing this property: cancelsTouchesInView
