UIScrollView子视图中的水平UISwipeGestureRecognizer？ （UIScrollView只需要识别垂直滚动） [英] Horizontal UISwipeGestureRecognizer in subview of UIScrollView ? (UIScrollView only needs to recognize vertical scrolling)

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.

推荐答案

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
