Question

我在UIView中有一个UIScrollView，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，那么它就可以了。

UserInteraction是所有视图的默认ON，但它仍然无效！

这一定是可能的，如果有人能指出我正确的方向，我真的很感激！

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，然后触及移动

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

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

触摸事件（touchesMoved）不能在UIScrollView中的UIViews上工作
