iOS的重叠视图和UIGestureRecognizer

Question

我有一个UIButton内这样一个观点：snapshot 01 http://imageshack.us/a/img827/7240/screenshot20130220at333.png

该按钮被绑定到一个IBAction：

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

我也有另一个视图，显示的集合最后一个视图：snapshot 02 http://img836.imageshack.us/img836/2104/screenshot20130220at339.png

在该视图的控制器，在某些时候我有这样的：

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

这：

- (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，当我在预览联系，我加载另一个视图。当我点击按钮时，我的问题就出现了。在这种情况下，函数-(IBAction)deleteButtonPressed: (id)sender不会被执行，但tapAction会执行。此外，按钮在按下时改变。我试图不添加GestureRecognizer，然后执行-(IBAction)deleteButtonPressed :(id)sender。

我做错了什么？如何在点击按钮时实现该目标，下方的视图不会捕获手势？

您需要实施shouldReceiveTouch方法（它是UIGestureRecognizerDelegate协议的一部分）。关于您的问题
