iPhone：如何找出哪個對象被觸及

Question

在我的UIViewController我有不同的UIViews，其中一些是我的自定義UIViews。如何知道哪個UIView被觸摸，我的習慣或不？

Answer 1

您可以爲每個視圖設置標籤。

view1.tag = y; 
UITapGestureRecognizer *tapGesture = 
    [[UITapGestureRecognizer alloc] initWithTarget:self 
              action:@selector(singleTapGestureCaptured:)]; 
tapGesture.numberOfTapsRequired = 1; 
[view1 addGestureRecognizer:tapGesture]; 

和singleTapGestureCaptured方法：

- (void)singleTapGestureCaptured:(UITapGestureRecognizer *)gesture 
{ 
    [[gesture view] tag]; 
    NSLog(@"tap captured for view :%d", [[gesture view] tag]); 
} 

Answer 2

您可以創建兩個UIGestureRecognizers，那麼你必須手勢識別你的意見這樣的關聯：

UITapGestureRecognizer * recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTap:)]; 
[view addGestureRecognizer:recognizer]; 

UITapGestureRecognizer * recognizerCustom = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapCustom:)]; 
[customView addGestureRecognizer:recognizer]; 

你知道什麼時候handleTap這樣：方法就是所謂的普通視圖十分感動，當你handleTapCustom ：被調用你的自定義視圖被調用。
