ios - 在动画期间防止 Cocos2D 触摸？

Question

在此动画中:

    - (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event {
    self.isTouchEnabled = NO;
    if (scoreLabel.opacity == 225) {
        NSLog(@"fadeOut");
        CCSequence *fadeOut = [CCSequence actions:[CCFadeOut actionWithDuration:0.5], [CCCallFuncN actionWithTarget:self 
        selector:@selector(enableTouches)], nil];
        [scoreLabel runAction:fadeOut];
        [livesLabel runAction:[[fadeOut copy] autorelease]];
    }
    else {
        NSLog(@"fadeIn");
        CCSequence *fadeIn = [CCSequence actions:[CCFadeIn actionWithDuration:0.5], [CCCallFuncN actionWithTarget:self 
        selector:@selector(enableTouches)], nil];
        [scoreLabel runAction:fadeIn];
        [livesLabel runAction:[[fadeIn copy] autorelease]];
         }
}

我正在尝试简单地淡出/淡入标签。但问题是，我希望确保在标签动画时不会调用此方法。

如果您查看代码，我会尝试通过调用此方法来实现:

    - (void)enableTouches {
    NSLog(@"ET");
        self.isTouchEnabled = YES;
}

但是好像不行。如果我在标签动画时触摸屏幕，它会在中途弄乱动画并且不会执行我想要的操作。

有什么想法吗？

谢谢!

我最后这样做是为了防止有人遇到同样的问题:

- (void)ccTouchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
    self.isTouchEnabled = NO;

    if(label1.opacity == 0 )
    {
        CCFadeIn* fadeIn = [CCFadeIn actionWithDuration:0.5];
        CCCallBlock* fadeCompleted = [CCCallBlock actionWithBlock:^{ self.isTouchEnabled = YES; }];     

        [label1 runAction:[CCSequence actions:fadeIn, fadeCompleted, nil]];
        [label2 runAction:[[fadeIn copy] autorelease]];
    }
    else
    {
        CCFadeOut* fadeOut = [CCFadeOut actionWithDuration:0.5];
        CCCallBlock* fadeCompleted = [CCCallBlock actionWithBlock:^{ self.isTouchEnabled = YES; }];     

        [label1 runAction:[CCSequence actions:fadeOut, fadeCompleted, nil]];
        [label2 runAction:[[fadeOut copy] autorelease]];
    }
}
