触摸事件（touchesMoved）在UIScrollView内的UIView上不起作用

Question

我在UIScrollView内有一个UIView ，这些视图的UIViewControllers没有收到触摸事件。 如果我从滚动视图中取出视图，则它可以工作。

UserInteraction默认为所有视图的ON，但仍然无法正常工作！

这一定有可能，如果有人能指出正确的方向，我将不胜感激！

非常感谢，

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]];

    }
}

将以下代码添加到实现文件中，然后触摸一下

 @interface UIScrollView(Custom)
    @end
    @implementation UIScrollView(Custom)

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