UICollectionView：将Tap Gesture Recognizer添加到collectionView超级视图

Question

集合视图不称为didSelectItemAtIndexPath。当我将Tap Gesture Recognizer添加到collectionView超级视图时，它总是响应轻击手势方法。

请帮助我，提前致谢！

Answer 1

试试这个

func gestureRecognizer(gestureRecognizer: UIGestureRecognizer, shouldReceiveTouch touch: UITouch) -> Bool {
    let touchPoint = touch.locationInView(superView)
    return !CGRectContainsPoint(collectionView.frame, touchPoint)
}

并确保委托已连接：

tapGestureRecognizer.delegate = self
