这篇文章主要介绍了touchesBegan: withEvent: 不执行解决的相关资料,需要的朋友可以参考下

touchesBegan: withEvent: / touchesMoved: withEvent: / touchesEnded: withEvent: 等只能被UIView捕获（如有问题请指出对请指出，路过的大牛请勿喷），当我们创建

UIScrollView 或 UIImageView 时，当点击时UIScrollView 或 UIImageView 会截获touch事件，导致touchesBegan: withEvent:/touchesMoved: withEvent:/touchesEnded: withEvent: 等方法不执行。解决办法：当UIScrollView 或 UIImageView 截获touch事件后，让其传递下去即可（就是传递给其父视图UIView）

可以通过写UIScrollView 或 UIImageView 的category 重写touchesBegan: withEvent: / touchesMoved: withEvent: / touchesEnded: withEvent: 等来实现
