Ios tvOS:DidUpdateFocusInText阻止点击次数

我在视图中有几个自定义按钮，并使用

didUpdateFocusInContext

将它们制作成自定义焦点动画，并且我在视图中添加了一个

UITapGestureRecognitizer

，当用户点击两次时，将运行一个方法！但问题是，当

didUpdateFocusInText

阻止双击操作，直到

聚焦上下文到达其末尾（这意味着直到最后一个按钮），那么方法将在没有聚焦上下文时触发！！！怎样才能防止这样的事情？这是我的密码：

- (void)didUpdateFocusInContext:(UIFocusUpdateContext *)context withAnimationCoordinator: (UIFocusAnimationCoordinator *)coordinator {
  
    
    //Setup focausing for main buttons
    for (UIButton *mainButton in _nextPrevButton){
        
        if (context.nextFocusedView == mainButton) {
            
            [UIView animateWithDuration:1 delay:0 usingSpringWithDamping:.40 initialSpringVelocity:.60 options:UIViewAnimationOptionAllowUserInteraction animations:^ {
                
                context.nextFocusedView.transform = CGAffineTransformMakeScale(1.2, 1.2);
                context.nextFocusedView.layer.shadowOffset = CGSizeMake(0, 0);
                context.nextFocusedView.layer.shadowOpacity = 1;
                context.nextFocusedView.layer.shadowRadius = 15;
                context.nextFocusedView.layer.shadowColor = [UIColor lightGrayColor].CGColor;
                context.nextFocusedView.layer.shadowOpacity = 1;
                
            } completion:nil];
            
        } else {
            
            [UIView animateWithDuration:1 delay:0 usingSpringWithDamping:.40 initialSpringVelocity:.60 options:UIViewAnimationOptionAllowUserInteraction animations:^ {
                context.previouslyFocusedView.transform = CGAffineTransformMakeScale(1, 1);
                context.previouslyFocusedView.layer.shadowOpacity = 0;
            } completion:nil];
        }
    }
    
    

if (context.nextFocusedView == _button1Focused) {   [self buttonFocused:context];   }   else if   (context.previouslyFocusedView == _button1Focused) {    [self buttonNotFocused:context];    }
if (context.nextFocusedView == _button2Focused) {   [self buttonFocused:context];   }   else if   (context.previouslyFocusedView == _button2Focused) {    [self buttonNotFocused:context];    }
if (context.nextFocusedView == _button3Focused) {   [self buttonFocused:context];   }   else if   (context.previouslyFocusedView == _button3Focused) {    [self buttonNotFocused:context];    }
 
    
}

攻丝方法：
我试过其他国家：

if (sender.state == UIGestureRecognizerStateBegan)
{
    // handling code
    NSLog(@"UIGestureRecognizerStateBegan ");
}


if (sender.state == UIGestureRecognizerStateEnded)
{
    // handling code
    NSLog(@" UIGestureRecognizerStateEnded ");
}

if (sender.state == UIGestureRecognizerStateRecognized)
{
    // handling code
    NSLog(@"UIGestureRecognizerStateRecognized");
}

但是没有成功

if (sender.state == UIGestureRecognizerStateBegan)
{
    // handling code
    NSLog(@"UIGestureRecognizerStateBegan ");
}


if (sender.state == UIGestureRecognizerStateEnded)
{
    // handling code
    NSLog(@" UIGestureRecognizerStateEnded ");
}

if (sender.state == UIGestureRecognizerStateRecognized)
{
    // handling code
    NSLog(@"UIGestureRecognizerStateRecognized");
}
