如何在点击标签后从标签中删除平移手势

Question

我正在添加多个带有平移手势的标签，并在每个标签上点按手势。但是，当我点按任何标签时，平移手势是否没有从其他标签中移除？

- (void)oneTap:(UITapGestureRecognizer *)gesture {

     tapedLabel=gesture.view.tag;
     //NSLog(@" tapped label is %d",numberOfLabel);

    //add pangesture
    self.pangesture = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(move:)] ;
    [self.pangesture  setMinimumNumberOfTouches:1];
    [self.pangesture  setMaximumNumberOfTouches:1];
    [ self.pangesture  setDelegate:self];

        for(int i=1;i<=numberOfLabel;i++)
        { 
             UILabel *label=[self.labelDict objectForKey:[NSString stringWithFormat:@"%d",i]];
            label.userInteractionEnabled=YES;
           if(i==tapedLabel)
           {
               //NSLog(@"i value %i tag value %d",i,tapedLabel);

               [label addGestureRecognizer:self.pangesture];
              // NSLog(@"remove  gesture over label %@",label);


           }
            else
            {
                //NSLog(@"i value %i tag value %d",i,tapedLabel);

           [label removeGestureRecognizer:self.pangesture];

               NSLog(@"add gesture over label %@",label);
            }

               }

   }

让我们试试这个删除你的panGesture，

如果您有两个标签手势，请使用以下内容。

if (label.gestureRecognizers.count > 1)
     [label removeGestureRecognizer:[label.gestureRecognizers lastObject]];
