触摸事件（touchesMoved）不工作在UIScrollView内的UIViews

我有一个UIScrollView内的UIView ，并且这些视图的UIViewControllers没有接收到触摸事件。 如果我将视图从滚动视图中移出，那么它就起作用了。

UserInteraction是所有视图的默认ON，但它仍然不起作用！

这一定是可能的，我会很感激，如果有人能指出我的方向正确！

非常感谢，

添加下面的代码到实现文件然后触动移动

  @interface UIScrollView(Custom) @end @implementation UIScrollView(Custom) -(void)touchesMoved:(NSSet *)touches withEvent:(UIEvent *)event { [super touchesMoved:touches withEvent:event]; } @end

您可以使用以下方法

  UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)]; [panRecognizer setMinimumNumberOfTouches:1]; [panRecognizer setMaximumNumberOfTouches:1]; [panRecognizer setDelegate:self]; [yourView addGestureRecognizer:panRecognizer]; 

并处理它

  -(void)move:(id)sender { if([(UIPanGestureRecognizer*)sender state] == UIGestureRecognizerStateChanged){ // This will return you location in view CGPoint currentPoint = [sender locationInView:self.view]; // This will return you location in Scrollview CGPoint scrollPoint = [sender locationInView:[[sender view] superview]]; } }
