我有一个主层。并且有 9 个子层添加。例如，一个主层板并添加了 9 层方格。

我想检测特定位置的触摸。

但它只检测到第一个。请帮我解决。

Here is a some code.

    @implementation Board

    @synthesize squares;

    - (id)init
    {

        self = [super initWithColor:ccc4(255, 255, 255, 255) width:300 height:300];

    }

    -(void)squaretouched

    }
    @end


    @implementation Square

    @synthesize state;

    -(id)init
    {
        self=[super initWithColor:ccc4(255, 255, 255, 255) width:100 height:100];

        if(self)
        {
            isTouchEnabled_=YES;
            //[self setRotation:30];

            CCSprite *square=[CCSprite spriteWithFile:@"square.png"];

            xImg=[CCSprite spriteWithFile:@"myCross.png"];

            oImg=[CCSprite spriteWithFile:@"myO.png"];



            [square setPosition:ccp(50, 50)];

            [xImg setPosition:ccp(50, 50)];

            [oImg setPosition:ccp(50, 50)];

            [xImg setVisible:NO];

            [self addChild:square];

            [self addChild:xImg];
            [self addChild:oImg];

            [self setOpacity:255];




        }
        return self;
    }



    -(BOOL)handleTouch:(CGPoint)location
    {
        NSLog(@"Me touched ");
        return YES;
    }

    And this is the TouchLayerColor class

        //CGPoint pos=ccp(50, 100);

        float x=pos.x;

        return  CGRectMake(x, y, w, h);
    }
    -(BOOL)handleTouch:(CGPoint)location
    {
        // dont hanle touch here
        return NO;
    }

    -(void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
    {
        NSLog(@"Coming in Touch");
        if(!self.visible || !self.isTouchEnabled)
        {
            NSLog(@"Coming in Touch if");
            return ;
        }
        UITouch *touch=[touches anyObject];
        CGPoint location=[touch locationInView:[touch view]];

        //convert the touch location from uikit to OpenGL Coordinates

        location=[[CCDirector sharedDirector] convertToGL:location];

        // did touch Happen in our rectangle ?

        if(CGRectContainsPoint([self rect], location))
        {
            [self handleTouch:location];
        }


    } 

    @end

当我单击任何 9 个正方形的正方形触摸方法时，会立即调用。

我不确定我有没有收到你的问题。无论如何，您可能会检测到层中的触摸，并且在触摸处理程序中，遍历子列表并将触摸位置传递给每个子。当然，您的子类都应使用调用的方法（即检测到的触摸）实现一个通用接口。这很像一个责任链模式http://it.wikipedia.org/wiki/Chain-of-responsibility_pattern
