UIScrollView响应touchesBegan事件

本文主要是介绍UIScrollView响应touchesBegan事件，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

用过UIScrollView的都会发现UIScrollView不会响应touch事件，这样就无法在touchesEnd方法中做一些事情了，比如关闭键盘等等。其实写个category就可以解决这个问题了，直接上代码：

@implementation UIScrollView (UITouchEvent)

- (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
