Question

接口：

@interface MyViewController : UIViewController <UIGestureRecognizerDelegate>

实现：

- (void)dismissPopup {
    NSLog(@"popup view dismissed");
}

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer 
           shouldReceiveTouch:(UITouch *)touch {

    return touch.view == self.view;
}

-(void)viewDidLoad
{
    [super viewDidLoad];

    UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc] 
            initWithTarget:self action:@selector(dismissPopup)];

    tapRecognizer.numberOfTapsRequired = 1;
    tapRecognizer.delegate = self;
    [self.view addGestureRecognizer:tapRecognizer];
    //...
}

从未触发解雇方法，为什么？我在iOS7上，使用故事板。

touch.view

的日志

MYAPP[5779:60b] <UIView: 0x17ecd8b0; frame = (0 0; 320 418);
 autoresize = RM+BM; layer = <CALayer: 0x17ecd910>>

self.view：

 MYAPP[5779:60b] <UIView: 0x17ecd590; frame = (0 64; 320 504);
 autoresize = RM+BM; gestureRecognizers = <NSArray: 0x17eb2c70>; layer
 = <CALayer: 0x17ecd5f0>>

我的工作正常。

如果你在断点 gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch 你可以确保touch.view在你的实现中实际上是self.view吗？
