UIScrollView 不能响应TouchesBegan / UITavbleView响应点击事件

• touchesBegan: withEvent: / touchesMoved: withEvent: / touchesEnded: withEvent: 等只能被UIView捕获

• 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

#import "UIScrollView+UITouch.h"  
  
@implementation UIScrollView (UITouch)  
  
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [[self nextResponder] touchesBegan:touches withEvent:event];
    [super touchesBegan:touches withEvent:event];
}

-(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event {
    [[self nextResponder] touchesMoved:touches withEvent:event];
    [super touchesMoved:touches withEvent:event];
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event {
    [[self nextResponder] touchesEnded:touches withEvent:event];
    [super touchesEnded:touches withEvent:event];
}
@end  

扩展 ： 让uitableView响应点击事件
