我正在使用 Cocos2d for iPhone 构建游戏，现在我正在尝试让 Touch 输入正常工作。我已经在多层场景中的独立控制层上启用了触摸响应，并且它工作正常 - 除了它仅在触摸位于我在单独层上的精灵顶部时触发触摸方法（单独层是实际上只是一个节点）。除了那个精灵之外，我没有任何其他屏幕内容。

这是我的控制层实现：

#import "ControlLayer2.h"

extern int CONTROL_LAYER_TAG;
@implementation ControlLayer2
+(void)ControlLayer2WithParentNode:(CCNode *)parentNode{
    ControlLayer2 *control = [[self alloc] init];
    [parentNode addChild:control z:0 tag:CONTROL_LAYER_TAG];
}

-(id)init{
    if (self=[super init]){

        [[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:self priority:0    swallowsTouches:YES];
    }
    return self;
}

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{
    CCLOG(@"touchbegan");
    return YES;
}

@end

这是带有子节点的图层，其中有一个精灵：

extern int PLAYER_LAYER_TAG;

int PLAYER_TAG = 1;

@implementation PlayerLayer
//reduces initializing and adding to the gamescene to one line for ease of use
+(void)PlayerLayerWithParentNode:(CCNode *)parentNode{
    PlayerLayer *layer = [[PlayerLayer alloc] init];
    [parentNode addChild:layer z:1 tag:PLAYER_LAYER_TAG];
}

-(id)init{
    if(self = [super init]){
        //add the player to the layer, know what I'm sayer(ing)?
        [Player playerWithParentNode:self];
    }
    return self;
}

@end

最后，包含它们的场景：

int PLAYER_LAYER_TAG = 1;
int CONTROL_LAYER_TAG = 2;
@implementation GameScene

+(id)scene{
    CCScene *scene = [CCScene node];
    CCLayer *layer = [GameScene node];
    [scene addChild:layer z:0 tag:0];
    return scene;
}

-(id)init{
    if(self = [super init]){
        //[[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:[self getChildByTag:0] priority:0 swallowsTouches:YES];
        //add the player layer to the game scene (this contains the player sprite)
        [ControlLayer2 ControlLayer2WithParentNode:self];
        [PlayerLayer PlayerLayerWithParentNode:self];

    }
    return self;
}

@end

如何使控制层响应所有触摸输入？

在 init 方法中添加此代码。

self.touchEnabled = YES;

并使用这个 ccTouchesBegan

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *myTouch = [touches anyObject];
    CGPoint location = [myTouch locationInView:[myTouch view]];
    location = [[CCDirector sharedDirector] convertToGL:location];

    //handle touch
}

删除代码中的这一行：

  [[[CCDirector sharedDirector]touchDispatcher] addTargetedDelegate:self priority:0    swallowsTouches:YES];

更新： 这里是完整的代码
