Ios 用户最后一次触摸哪个标签，以及如何将其从视图中删除

我想知道如何知道用户最后触摸的标签以及如何从视图中删除该特定标签。我知道如何更改所有标签的属性，但我不知道如何找出最后选择的标签

这就是如何将标签添加到视图中

myNewLabel.text =textField.text;
numberOfLabels++;
myNewLabel.tag=numberOfLabels;
[self.view addSubview:myNewLabel];
[shirtBackgroundView addSubview:myNewLabel];
[myNewLabel addGestureRecognizer:panGestureRecognizer];
[myNewLabel addGestureRecognizer:rotateGestureRecognizer];
[myNewLabel addGestureRecognizer:PinchGestureRecognizer];
myNewLabel.userInteractionEnabled=YES;
myNewLabel.backgroundColor=[UIColor clearColor]; 
[arrayForLabels addObject:myNewLabel];   

下面是我如何更改所有标签的颜色

    for(int i=0;i<numberOfLabels;i++)
    {
        UILabel *tempLabel = [arrayForLabels objectAtIndex:i];
        tempLabel.textColor=[UIColor redColor];
    }



 -(void)labelMoved:(UIPanGestureRecognizer *)recognizer
{
    CGPoint translation = [recognizer translationInView:self.view];
    recognizer.view.center = CGPointMake(recognizer.view.center.x + translation.x,
                                         recognizer.view.center.y + translation.y);
    [recognizer setTranslation:CGPointMake(0, 0) inView:self.view];



    if (recognizer.state == UIGestureRecognizerStateEnded) {

        CGPoint velocity = [recognizer velocityInView:self.view];
        CGFloat magnitude = sqrtf((velocity.x * velocity.x) + (velocity.y * velocity.y));
        CGFloat slideMult = magnitude / 200;
        NSLog(@"magnitude: %f, slideMult: %f", magnitude, slideMult);

        float slideFactor = 0.1 * slideMult; // Increase for more of a slide
        CGPoint finalPoint = CGPointMake(recognizer.view.center.x + (velocity.x * slideFactor),
                                         recognizer.view.center.y + (velocity.y * slideFactor));
        finalPoint.x = MIN(MAX(finalPoint.x, 0), self.view.bounds.size.width);
        finalPoint.y = MIN(MAX(finalPoint.y, 0), self.view.bounds.size.height);

        [UIView animateWithDuration:slideFactor*2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
            recognizer.view.center = finalPoint;
        } completion:nil];


    }

}

for（int i=0；i可以在.h类中将属性声明为UILabel*lastSelectedLabel；并在识别器中声明

-(void)labelMoved:(UIPanGestureRecognizer *)recognizer{
          if(lastSelectedLabel!=nil){
                [lastSelectedLabel removeFromSuperview];
                lastSelectedLabel=recognizer.view;

          }else
              lastSelectedLabel=recognizer.view;
}

我认为以上方法应该有效

谢谢。
对于检测
UIlabels
以捕获点击：

label.userInteractionEnabled = YES;
 UIGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapRecieved:)]; 
[label addGestureRecognizer:tap];
[tap release];

//对每个附加标签重复此操作
当你触摸

-(void) tapRecieved:(UITapGestureRecognizer *)tap{  
      currentLabel = (UILabel *) tap.view;
        [currentLabel removeFromSuperview];
 }
