UIScrollView和UIButton在辅助事件冲突中进行补正

Question

I hava a TableViewController, When I tap on a cell it pushed into a detail controller. On the detail controller, I have a scrollview and a UIButton on it. I want single tap on the scrollview to back to TableView and touch the UIButton to do other things. In the detail controller:

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action: @selector(singleTap:)];
tapRecognizer.cancelsTouchesInView = NO;
[self.scrollView addGestureRecognizer:tapRecognizer];

Now, when I tap the scrollview it back to tableview, but when I tap the UIButton, It also back to tableview, How to fix it? Thank you.

Answer 1

1. A simple suggestion to make the tap with two fingers rather than a single finger.
2. Subclass the scroll view and implement it's touches methods. If the touch area is the same as the button frame, return NO to the gesture delegate. Button will take the touch.
