Objective c SpriteKit手势识别器

嗨，我想在我的精灵套件游戏中使用手势识别器，我写了这段代码

@interface GameScene() <UIGestureRecognizerDelegate>{

  UISwipeGestureRecognizer *swipeGestureLeft;
  ISwipeGestureRecognizer *swipeGestureRight;
}
@end

@implementation GameScene
-(id)initWithSize:(CGSize)size{

    if(self = [ super initWithSize:size]){

    }

    return  self;
}

-(void)didMoveToView:(SKView *)view{

    swipeGestureLeft = [[UIGestureRecognizer alloc]initWithTarget:self action:@selector(swipeLeft)];
    [swipeGestureLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
    [view addGestureRecognizer:swipeGestureLeft];

    swipeGestureRight = [[UIGestureRecognizer alloc]initWithTarget:self action:@selector(swipeRight)];
    [swipeGestureRight setDirection:UISwipeGestureRecognizerDirectionRight];
    [view addGestureRecognizer:swipeGestureRight];
}

- ( void ) willMoveFromView: (SKView *) view {

    [view removeGestureRecognizer: swipeGestureLeft ];
    [view removeGestureRecognizer: swipeGestureRight];
}

-(void)swipeLeft:(UISwipeGestureRecognizer*) recognizer{

    NSLog@"Left"'
}

-(void)swipeRight:(UISwipeGestureRecognizer*) recognizer{

    NSLog@"Right"'
}


@end

@界面游戏场景（）{
UISwipegestureRecognitor*swipeGestureLeft；
IsWipegestureRecognitor*swipeGestureRight；
}
@结束
@实现游戏场景
-（id）initWithSize:（CGSize）大小{
if（self=[super initWithSize:size]）{
}
回归自我；
}
-（void）didMoveToView:（SKView*）视图{
swipeGestureLeft=[[UIgestureRecognitizer alloc]initWithTarget:self action:@selector（swipeLeft）]；
[swipeGestureLeft设置方向：UISwipegestureRecognitizerDirectionLeft]；
[查看AddGestureRecognitor:swipeGestureLeft]；
swipeGestureRight=[[UIgestureRecognitizer alloc]initWithTarget:self action:@selector（SwiperRight）]；
[swipeGestureRight设置方向：UISwipegestureRecognitizerDirectionRight]；
[查看AddGestureRecognitor:swipeGestureRight]；
}
-（void）willMoveFromView:（SKView*）视图{
[查看移除检测识别器：swipeGestureLeft]；
[查看RemovegestureRecognitor:SwipegTestureRight]；
}
-（void）swipeLeft:（UISwipegestureRecognitor*）识别器{
NSLog@“左”
}
-（void）swipeRight:（UISwipegestureRecognitor*）识别器{
NSLog@“正确”'
}
@结束

我想一切都没问题，但我的手势不起作用，我没有错误消息，我是否应该在我的应用程序中添加一些东西，或者我应该在我的视图控制器中添加一些东西，或者你们能给我推荐一本关于如何在精灵工具包中使用手势的教程，

试试这段代码，它对我很有用。我猜你是打字错误了

 @interface GameScene() <UIGestureRecognizerDelegate>{

        UISwipeGestureRecognizer *swipeGestureLeft; 
        UISwipeGestureRecognizer *swipeGestureRight;
        UITapGestureRecognizer *doubleTapGesture;
    }

    @end

    @implementation GameScene

    -(void)didMoveToView:(SKView *)view {
        /* Setup your scene here */

        //You should use UISwipeGestureRecognizer instead of UIGestureRecognizer here.

        swipeGestureLeft = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeLeft:)];
        [swipeGestureLeft setDirection:UISwipeGestureRecognizerDirectionLeft];
        [view addGestureRecognizer:swipeGestureLeft];


        //Note that swipeRight has a parameter, so you  have to change swipeRight to swipeRight: to silent the compiler warning.
        swipeGestureRight = [[UISwipeGestureRecognizer alloc]initWithTarget:self action:@selector(swipeRight:)];
        [swipeGestureRight setDirection:UISwipeGestureRecognizerDirectionRight];
        [view addGestureRecognizer:swipeGestureRight];


        //double tap detection
        doubleTapGesture = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapTap:)];
       [doubleTapGesture setNumberOfTapsRequired:2];
       [view addGestureRecognizer:doubleTapGesture];
    }

    -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
        /* Called when a touch begins */


    }

    -(void)update:(CFTimeInterval)currentTime {
        /* Called before each frame is rendered */
    }

    - ( void ) willMoveFromView: (SKView *) view {


        [view removeGestureRecognizer: swipeGestureLeft ];

        [view removeGestureRecognizer: swipeGestureRight];

        [view removeGestureRecognizer: doubleTapGesture];
    }

    -(void)swipeLeft:(UISwipeGestureRecognizer*) recognizer{

        NSLog(@"Left");

    }

    -(void)swipeRight:(UISwipeGestureRecognizer*) recognizer{

        NSLog(@"Right");


    }

   -(void)tapTap:(UITapGestureRecognizer*) recognizer{

        NSLog(@"Tap tap");

    }

    @end

为什么要删除手势识别器？有必要吗？@LinusG。我猜是因为场景转换。这些swipeRight和swipeLeft方法在该场景中定义。而且识别器在场景转换后不会被移除，所以应用程序会崩溃。兄弟，非常感谢，这个手势很好，所以我认为如果我使用轻拍手势识别器，就像我使用刷卡手势一样，没有问题吗？不客气，很高兴它有帮助……您可以用这种方式在SKView上使用任何手势识别器。@Omar再次检查代码，我为您添加了一个tap识别器的示例。
