使用UIGestures刪除選定的uiimage？

Question

我試圖通過做一個長按手勢刪除圖像... 問題是我可以在同一視圖上有多個圖像。並可能想通過按住圖像來刪除每個圖像。

所以可以說我有：

@property (nonatomic, retain) IBOutlet UIImageView *Image1; 
@property (nonatomic, retain) IBOutlet UIImageView *Image2; 
@property (nonatomic, retain) IBOutlet UIImageView *Image3; 

都在同樣的觀點。 現在我按住Image1。 如何獲得Longpress手勢以知道Ive選擇了Image1？

- (void)handleDelete:(UILongPressGestureRecognizer *)recognizer { 
    //Something in here to detect image is selected and delete :) 
} 

謝謝！

Answer 1

給這個UIGestureRecognizerDelegate在.h文件中和後，試試這個代碼...

UILongPressGestureRecognizer *longpressGesture = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressHandler:)]; 
    longpressGesture.minimumPressDuration = 5; 
    [longpressGesture setDelegate:self]; 
    [self.yourImages addGestureRecognizer:longpressGesture]; 
    [longpressGesture release]; 

    - (void)longPressHandler:(UILongPressGestureRecognizer *)gestureRecognizer { 
     NSLog(@"longPressHandler"); 
     UIImageView *tempImage=(UIImageView*)[gestureRecognizer view]; 
     [tempImage removeFromSuperview]; 
    }

添加UILongPressGestureRecognizer個人圖像，然後當檢測到的手勢刪除它們，就像下面：

UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(longPressDetected:)]; 
longPressRecognizer.minimumPressDuration = 3; 
longPressRecognizer.numberOfTouchesRequired = 1; 
[self.Image1 addGestureRecognizer:longPressRecognizer]; 
[self.Image2 addGestureRecognizer:longPressRecognizer]; 
[self.Image3 addGestureRecognizer:longPressRecognizer]; 

- (IBAction)longPressDetected:(UILongPressGestureRecognizer *)sender { 
    NSLog(@"Long Press"); 
    // Delete/Remove sender object 
}
