Question

I have a button and a gesture recognition and when the button is pressed only one method should be called.

Most cases only the gesture recognition is being called which is fine but every no and then the button gets called to which causes problems.

I have a view and then a scroll view. All my buttons are on the scroll view

Answer 1

you can implement this in your view controller and assign it to the delegate of the gesture recognizer.

- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
    CGPoint p = [gestureRecognizer locationInView:self.view];
    UIView *view = [sefl.view hitTest:p withEvent:nil];
    if ([view isKindOfClass:[UIButton class]]) {
        return NO;
    }
    return YES;
}

or you can implement - (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch with similar logic if gestureRecognizerShouldBegin: does not suit.
