克隆阵列CCSprite

Question

请咨询: Cocos2d。我有一个数组CCSprite：

movableSprites = [[NSMutableArray alloc] init];
        NSArray *images = [NSArray arrayWithObjects:@"bird.png", @"cat.png", @"dog.png", @"turtle.png", nil];
        for(int i = 0; i < images.count; ++i) {
            NSString *image = [images objectAtIndex:i];
            CCSprite *sprite = [CCSprite spriteWithFile:image];
            float offsetFraction = ((float)(i+1))/(images.count+1);
            sprite.position = ccp(winSize.width*offsetFraction, winSize.height/2);
            [self addChild:sprite];
            [movableSprites addObject:sprite];
        }

创建数组的克隆: MovableSprites2。第二个数组被添加到场景中。我有一个方法: selectSpriteForTouch：

- (Void) selectSpriteForTouch: (CGPoint) touchLocation {
    CCSprite * newSprite = nil;
    for (CCSprite * sprite in movableSprites) {
        if (CGRectContainsPoint (sprite.boundingBox, touchLocation)) {
            newSprite = sprite;
            break;
        }
    }
    if (newSprite! = selSprite) {
        [selSprite stopAllActions];
        [selSprite runAction: [CCRotateTo actionWithDuration: 0.1 angle: 0 ]] ;
        CCRotateTo * rotLeft = [CCRotateBy actionWithDuration: 0.1 angle: -4.0];
        CCRotateTo * rotCenter = [CCRotateBy actionWithDuration: 0.1 angle: 0.0];
        CCRotateTo * rotRight = [CCRotateBy actionWithDuration: 0.1 angle: 4.0];
        CCSequence * rotSeq = [CCSequence actions: rotLeft, rotCenter, rotRight, rotCenter, nil];
        [newSprite runAction: [CCRepeatForever actionWithAction: rotSeq]];
        selSprite = newSprite;

    }
}

因此，当您单击任何CCSprite时，CCSprite开始旋转。请告诉我，通过单击CCSprite的第一个数组之一，出现了与第二个数组完全相同的CCSprite，他开始旋转CCSprite，而不是从第一个数组和第二个出现的数组中旋转)

若要创建使用与已存在的sprite相同的纹理(图片)的sprite，请执行以下操作：

CCSprite* newSprite = [CCSprite spriteWithTexture:existingSprite.texture
                                             rect:existingSprite.textureRect];
