To trigger UIButton touch action within a view that has a UITapGestureRecognizer, you have to implement the the UIGestureRecognizerDelegate protocol and its method -(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch.
- (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
}
or
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
if ([touch.view isKindOfClass:[UIButton class]]){
return FALSE;
}
return TRUE;
}
