Objective c ccTouchBegin触点未正确读取

我制作了这个ccTouchBegin方法：

- (BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {



    CGPoint location = [touch locationInView:[touch view]];
    location = [[CCDirector sharedDirector] convertToGL:location];

    CGPoint pos = [self getChildByTag:1].position;


    CGSize size = [self getChildByTag:1].contentSize;
    float padding = 3;
    float w = size.width+padding*2;
    float h = size.height+padding*2;

    // first row
    CGRect rect1 = CGRectMake(pos.x-w/2, pos.y-h/2, w/3, h/3);
    CGRect rect2 = CGRectMake(pos.x-(w*(2/3)/2), pos.y-h/2, w/3, h/3);
    CGRect rect3 = CGRectMake(pos.x+(w*(2/3)/2), pos.y-h/2, w/3, h/3);
    //second row
    CGRect rect4 = CGRectMake(pos.x-w/2, pos.y-(h*(2/3)/2), w/3, h/3);
    CGRect rect5 = CGRectMake(pos.x-(w*(2/3)/2), pos.y-(h*(2/3)/2), w/3, h/3);
    CGRect rect6 = CGRectMake(pos.x+(w*(2/3)/2), pos.y-(h*(2/3)/2), w/3, h/3);
    //third  row
    CGRect rect7 = CGRectMake(pos.x-w/2, pos.y+(h*(2/3)/2), w/3, h/3);
    CGRect rect8 = CGRectMake(pos.x-w/2, pos.y+(h*(2/3)/2), w/3, h/3);
    CGRect rect9 = CGRectMake(pos.x-w/2, pos.y+(h*(2/3)/2), w/3, h/3);


    if (CGRectContainsPoint(rect1, location)) {
        NSLog(@"rect1");
    } else if (CGRectContainsPoint(rect2, location)) {
        NSLog(@"rect2");
    } else if (CGRectContainsPoint(rect3, location)) {
        NSLog(@"rect3");
    } else if (CGRectContainsPoint(rect4, location)) {
        NSLog(@"rect4");
    } else if (CGRectContainsPoint(rect5, location)) {
        NSLog(@"rect5");
    } else if (CGRectContainsPoint(rect6, location)) {
        NSLog(@"rect6");
    } else if (CGRectContainsPoint(rect7, location)) {
        NSLog(@"rect7");
    } else if (CGRectContainsPoint(rect8, location)) {
        NSLog(@"rect8");
    } else if (CGRectContainsPoint(rect9, location)) {
        NSLog(@"rect9");
    }

    return YES;
}

它很简单，它获取接触点，然后获取孩子的内容大小和位置，并划分孩子所在的位置，形成一个3x3表。但现在它不起作用，即使我尝试触摸整个屏幕，我也不会得到任何NSLOG。知道怎么了吗

。断点允许您立即测试方法或代码行是否正在执行

除非使用作为CCLayer中触摸的默认处理程序，否则不会调用

CCTouchStart

方法。为此，请在CCLayer类中重写registerWithTouchDispatcher，但不要调用超级实现：

---

您不需要删除该委托。CCLayer类为您处理这些

-(void) registerWithTouchDispatcher
{
  [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self 
                                                   priority:0
                                            swallowsTouches:NO];
}
