如何從標籤中刪除平底鍋手勢後，點擊標籤

Question

我正在添加多個標籤與平底鍋手勢和點擊每個標籤上的手勢。但是當我點擊任何標籤時，平底鍋手勢不是從其他標籤刪除？

- (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); 
      } 

       } 

    }

讓我們試試這個刪除您panGesture，

如果你有兩個比劃了標籤，使用以下。

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