如果您希望能夠檢測到cocos2d中的觸摸,則需要在init方法中將isTouchEnabled屬性設置爲YES。您現在可以利用觸摸事件。

接下來,創建新的方法:

- (void)ccTouchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { 
    //This method gets triggered every time a tap is detected 
    NSSet *allTouches = [event allTouches]; //Get all the current touches in the event 
    UITouch *aTouch = [allTouches anyObject]; //Get one of the touches, multitouch is disabled, so there is only always going to be one. 
    CGPoint pos = [aTouch locationInView:touch.view]; //Get the location of the touch 
    CGPoint ccPos = [[CCDirector sharedDirector] convertToGL:pos]; //Convert that location to something cocos2d can use 
    if (CGRectContainsPoint(yourSprite.boundingBox, ccPos)) //Method to check if a rectangle contains a point 
    { 
     yourSprite.visible = NO; //Make your sprite invisible 
    } 

} 

,你可能要採取最終有以下優勢其他方法:

- (void)ccTouchesMoved:(NSSet *)touches withEvent:(UIEvent *)event; 
- (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event; 
- (void)ccTouchesCancelled:(NSSet *)touches withEvent:(UIEvent *)event; 

希望這有助於。
