iOS的重疊視圖和UIGestureRecognizer

Question

我有一個UIButton內這樣一個觀點：snapshot 01 http://imageshack.us/a/img827/7240/screenshot20130220at333.png

該按鈕被綁定到一個IBAction：

-(IBAction)deleteButtonPressed :(id)sender{ 
    NSLog(@"DeleteButtonPressed"); 
} 

我也有另一個視圖，顯示的集合最後一個視圖：snapshot 02 http://img836.imageshack.us/img836/2104/screenshot20130220at339.png

在該視圖的控制器，在某些時候我有這樣的：

UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapAction:)]; 
    tapGesture.numberOfTapsRequired = 1; 
    tapGesture.numberOfTouchesRequired = 1; 
    [preview addGestureRecognizer:tapGesture]; 

這：

- (void)tapAction:(UIGestureRecognizer *)gestureRecognizer{ 

    EditorViewController *vc = [self.storyboard instantiateViewControllerWithIdentifier:@"EditorViewController"]; 
    vc.narration = preview.narration; 
    self.navigationItem.backBarButtonItem.style = UIBarButtonItemStylePlain; 
    self.navigationItem.backBarButtonItem.title = @"Done"; 
    vc.navigationItem.backBarButtonItem.style = UIBarButtonItemStylePlain; 
    vc.navigationItem.backBarButtonItem.title = @"Done"; 
    [self.navigationController pushViewController:vc animated:YES]; 
} 

所以，當我在預覽聯繫，我加載另一個視圖。當我點擊按鈕時，我的問題就出現了。在這種情況下，函數-(IBAction)deleteButtonPressed: (id)sender不會被執行，但tapAction會執行。此外，按鈕在按下時改變。我試圖不添加GestureRecognizer，然後執行-(IBAction)deleteButtonPressed :(id)sender。

我做錯了什麼？如何在點擊按鈕時實現該目標，下方的視圖不會捕獲手勢？

您需要實施shouldReceiveTouch方法（它是UIGestureRecognizerDelegate協議的一部分）。關於您的問題
