当我的 ccLayer 具有 loadNibNamed 时，如何识别 ccTouches 事件

Question

我的问题是我没有找到通过 UIScrollView “刺穿”的解决方案，以便 ccLayer 可以识别 ccTouch 事件

   self.isTouchEnabled = YES;
    [[NSBundle mainBundle] loadNibNamed:@"myLayer" owner:self options:nil];

...

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

-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {
        CGPoint location = [self convertToWorldSpace:[self convertTouchToNodeSpace:touch]];

有什么想法如何创建委托或其他解决方案来绕过 UI 并与 cc 对话？

Answer 1

今天早上我在使用 Cocos2D v1.0.0 时遇到了这个问题。我的解决方案是在该层的 init 方法中包含 CCTouchDispatcher 方法调用，然后 UIView 内的该层将识别触摸。

-(id) init
{
  if ((self = [super init]) != nil) {
    // do stuff
    [[CCTouchDispatcher sharedDispatcher] addTargetedDelegate:self priority:0 swallowsTouches:YES];
  }
  return self;
}

-(BOOL) ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event
{
  CGPoint location = [self convertToNodeSpace:[[CCDirector sharedDirector] convertToGL:[touch locationInView:[touch view]]]];
  NSLog(@"TouchBegan at x:%0.2f, y:%0.2f", location.x, location.y);

  return YES;
}

另一种解决方案是使用 ccTouchesBegan 方法：

-(id) init
{
  if ((self = [super init]) != nil) {
    // do stuff
    self.isTouchEnabled = YES;
  }
  return self;
}


-(void) ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{   
  for (UITouch *thisTouch in touches) {
    CGPoint location = [self convertToNodeSpace:[[CCDirector sharedDirector] convertToGL:[thisTouch locationInView:[thisTouch view]]]];
    NSLog(@"TouchesBegan at x:%0.2f, y:%0.2f", location.x, location.y); 
  }
}

请注意，这两种触摸方法具有不同的方法来让您的应用程序知道它应该响应触摸。您无法混合搭配您想要响应触摸的方式以及您想要观察的触摸。
