Ios 使用UIScrollView查看时的UIPangestureRecognitor

我有一个使用

uipangestrerecognizer

的视图

UIPanGestureRecognizer *recognizer = [[UIPanGestureRecognizer alloc]
                                          initWithTarget:self action:@selector(handlePan:)];
    [recognizer setMaximumNumberOfTouches:1];
    [recognizer setDelegate:self];

[self.view addGestureRecognizer: recognizer];

=======
-(void) handlePan:(UIPanGestureRecognizer*)gestureRecognizer
{
  move subview of self.view
}

子视图内部有一个滚动视图。当滚动视图位于水平滚动的末尾时，如何使用事件-

handlePan:

捕捉手势

---

您可以使用以下功能：

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer

---

我从上周开始就在panGesture工作。在我看来，这里有两个问题

1） 用户体验设计。UIScrollView:UIView是“触摸”可识别的

-（BOOL）触摸应开始：（NSSet*）触摸事件：（UIEvent*）在视图中的事件：（UIView*）视图

UIPangestureRecognitor还检测“触摸”

-（CGPoint）触摸位置：（NSUInteger）查看中的触摸索引：（UIView*）视图；//特定触摸的位置

从用户体验的角度来看，纯粹从设计的角度来看，如何在一个UI区域中指出两次触摸之间的差异

2） 代码。看起来您只是想平移视图（UIScrollView或其他UIView的视图）

}
如果要捕捉滚动视图点击手势，请将UIPANGestureRecognitor设置为滚动视图
UIPanGestureRecognizer *recognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:@selector(handlePan:)];

// no need to set the number of touches to 1. 1 is default number. 
yourView = [[UIImageView alloc]init]; // or initWithFrame
// add the recognizer to your view 
[youView addGestureRecognizer:recognizer];
//add this view to the mainView
[self addSubview: yourView];
// then process @selector(handlePan:)
-(void) handlePan:(UIPanGestureRecognizer*)gestureRecognizer
{ 
// this method is to deal with location of the panGesture itself, not other third views.
CGPoint touchLocation = [gestureRecognizer locationInView:self]; 
yourView.center = touchLocation;
