[cocos2d] 谁摸了我一下----触摸事件处理

1. 设置接受触摸事件，可在init方法里面写上

[self setTouchEnabled: YES];

 旧版为self.isTouchEnabled = YES;

xcode会报Deprecations ‘setIsTouchEnabled:’ is deprecated waring

2. 覆盖方法

- (void) registerWithTouchDispatcher{[[[CCDirector shareDirector] touchDispatcher] addTargetedDelegate:self priority:INT32_MIN+1 swallowsTouches:YES];}

 

3. 捕获触摸

-(BOOL)ccTouchBegan:(UITouch *)touches withEvent:(UIEvent *)event{//触摸开始时候做什么}-(void)ccTouchMoved:(UITouch *)touches withEvent:(UIEvent *)event{}-(void)ccTouchEnded:(UITouch *)touches withEvent:(UIEvent *)event{//触摸结束时候做什么}

4. 获取触摸位置

-(BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event{//获得触摸坐标（iphone UI）CGPoint touchLocation = [touch locationInView:[touch view]];//将坐标转变成openGL的格式touchLocation = [[CCDirector shareDirector]converToGL:touchLocation;/**PS:iphone的坐标原点是左上角，x往右增加，y往下增加*openGL的坐标原点是左下角，x往右增加，y往上增加*///获得sprite，spriteTag在前面enum结构中定义，以区别不同的tag。所以下面需要判断其是否为CCSprite类，以防判断错误
CCNode *node = [self getChildByTag:spriteTag];//判断是否为CCSprite类!!!NSAssert([node isKindOfClass:[[CCSpite class]], @"not a sprite");//类型转换CCSprite *sprite = (CCSprite*)node;//判断触摸位置是否为spriteBOOL isTouchSprite = CGRectContainsPoint([sprite boundingBox], touchLocation);if (isTouchSprite){//do sth}//若触摸到sprite则把触摸事件吞了（=，= 即其它CCLayer不再响应该触摸事件）return isTouchSprite;}

先写到这里，遇到其他再补充。
