UIScrollView子视图中的水平UISwipeGestureRecognizer？ （UIScrollView只需要识别垂直滚动）
问题描述：
我有一个UIScrollView，我添加了一个子视图。 scrollview垂直滚动，这就应该做。我现在想在UISwipeGestureRecognizer的帮助下识别子视图中的左/右滑动。我知道这是可能的，但是我没有遇到过解决方案而且有几次尝试都没有成功。
I have a UIScrollView where I added a subview. The scrollview scrolls fine vertically and that is all it should do. I would now like to recognize left/right swipes in the subview with the help of a UISwipeGestureRecognizer. I know it is possible, but I have not come across a solution and several tries have been unsuccessful.
答
试试这些：
-
设置
UIGestureRecognizer的代表和
实施 shouldRecognizeSimultaneouslyWithGestureRecognizer ：
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{
return YES;
}
实施 shouldReceiveTouch ：
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
return YES;
}
希望这有助于
