Question

我创建了主UIView。然后在其上添加两个UIView。

并将UIGestureRecognizer附加到mainView。但是当我点击主视图时，它只能检测到mainView的一半。

有谁知道这是为什么，

-(void)addTapGesture:(UIView*)view
{
    view.userInteractionEnabled=YES;

    UITapGestureRecognizer *oneFingerTwoTaps = 
    [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(detailInfo:)] autorelease];

    // Set required taps and number of touches
    [oneFingerTwoTaps setNumberOfTapsRequired:1];
    [oneFingerTwoTaps setNumberOfTouchesRequired:1];
    oneFingerTwoTaps.delegate=self; //gesturRecognize delegate
    // Add the gesture to the view
    [view addGestureRecognizer:oneFingerTwoTaps];           
}

Answer 1

检查是否有其他视图重叠你的mainView图层，或者你的mainView上是否添加了其他一些可能取消你的主视图的访客

Answer 2

使您的ViewController符合<UIGestureRecoganizerDelegate>

然后在viewController中调用delegate方法。

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
    NSLog ("Touch View : %@", touch.view);
    NSLog ("GestureRecoganizer View : %@", touch.view); //Check if both views are same
    if ([touch.view isKindOfClass: [YourViewClass class]]) {
        return NO;
    }
    return YES;
}

希望它能帮助你...快乐编码：）

UIGestureRecognizer没有完全检测到我的UIView
