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
