     [firstBtn addGestureRecognizer:PressRecognizer1]; 

-(void)handlePress:(UITapGestureRecognizer*)PressRecognizer { 

    NSLog(@"working"); 
     if (PressRecognizer.state == UIGestureRecognizerStateBegan) { 
      UIButton *whichButton=(UIButton *)[PressRecognizer view]; 
      NSLog(@"whichButton %d\n",whichButton.tag); 
      if (whichButton.tag == 0) { 
       NSLog(@"currentImageId1 %d",currentImageId1); 
       [delegate imageZoom:currentImageId1];

「UITapgesture不能處理圖像」 - 代碼中的圖像在哪裏？ – 2013-03-07 10:59:47

我在按鈕上添加了圖像。 – user2134883 2013-03-07 11:00:57

從蘋果文檔：

儘管抽頭是離散的手勢，它們是分立的手勢識別的每個狀態;因此相關聯的動作消息在手勢開始時發送並針對每個中間狀態發送，直到（並且包括）手勢的結束狀態。因此，處理的輕敲姿勢代碼應該測試手勢的狀態，例如：

- (void)handleTap:(UITapGestureRecognizer *)sender { 
    if (sender.state == UIGestureRecognizerStateEnded)  
    {   
      // handling code  
    } 
}

，如果你的NSLog（@「％d」，sender.state）裏面的方法（前if語句）你」 LL看到，該方法只獲得與UIGestureRecognizerStateEnded狀態發射，因此，你應該改變你的

if (PressRecognizer.state == UIGestureRecognizerStateBegan)

到

if (PressRecognizer.state == UIGestureRecognizerStateEnded)
