cocos2d修改数组

Question

我已经将精灵添加到我的NSMutable数组中，现在我想要找到它们;我正在使用这些方法：

- (void)selectSpriteForTouch:(CGPoint)touchLocation { 
     for (CCSprite *sprite in selectedSpritesArray) { 
      if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {    
       newSprite = sprite; 
       break; 
      } 
     } 
} 

- (BOOL)ccTouchBegan:(UITouch *)touch withEvent:(UIEvent *)event {  
    CGPoint touchLocation = [self convertTouchToNodeSpace:touch]; 
    [self selectSpriteForTouch:touchLocation];  
    return TRUE;  
} 

我该如何正确地做到这一点？现在我无法访问一些重叠的精灵。

谢谢！如果您要访问重叠精灵

建议：

- (NSMutableArray*)selectSpriteForTouch:(CGPoint)touchLocation { 
     NSMutableArray *sprites = [[NSMutableArray alloc] init]; 
     for (CCSprite *sprite in selectedSpritesArray) { 
      if (CGRectContainsPoint(sprite.boundingBox, touchLocation)) {    
       [sprites addObject:sprite]; 
      } 
     } 

     // dont forget to release this array when you are done with it 
     return sprites; 
}
