UIPanGestureRecognizer on multiple view - Objective-c

Question

我有2個imageviews，我希望能夠移動。這是我的代碼：

panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(gestureRecognizerMethod:)]; 

imageview = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; 
imageview.frame = CGRectMake(390, 100, 80, 16); 
imageview.userInteractionEnabled = YES; 
[imageview addGestureRecognizer:panRecognizer]; 
[self addSubview:imageview]; 

imageview2 = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; 
imageview2.frame = CGRectMake(390, 120, 80, 17); 
imageview2.userInteractionEnabled = YES; 
[imageview2 addGestureRecognizer:panRecognizer]; 
[self imageview2]; 

在我gestureRecognizer方法：

- (void)gestureRecognizerMethod:(UIPanGestureRecognizer *)recognizer 
{ 
    if (recognizer.view == imageview) 
    { 
     if (recognizer.state == UIGestureRecognizerStateBegan || recognizer.state == UIGestureRecognizerStateChanged) 
     { 
      CGPoint startPoint = [recognizer locationInView:self]; 
      imageview.center = startPoint; 
     } 
    } 
    if (recognizer.view == imageview2) 
    { 
     if (recognizer.state == UIGestureRecognizerStateBegan || recognizer.state == UIGestureRecognizerStateChanged) 
     { 
      CGPoint startPoint = [recognizer locationInView:self]; 
      imageview2.center = startPoint; 
     } 
    } 
} 

我只能夠移動視圖之一。哪裏不對？

爲第二個圖像視圖創建一個新的手勢識別器。您可以對兩個識別器使用相同的目標和操作，但只能將任意一個識別器附加到單個視圖。
