内存泄漏与CIColor spritekit

我创建了一个可生成hud项的类，此hud项可以为生成的纹理设置动画，该纹理是使用cicolor创建的渐变，然后将其保存到uiimage中，而uiimage又用于sktexture。我现在已经注意到我在我的应用程序中获得了大量的内存增长，并通过乐器运行它已经向我展示了这一点，但我不能为生活弄清楚最新情况：

这是我得到的错误enter image description here 你无法真正看到这个问题所以它给了我91.4％的代码：

animatedGraphic = [[SKSpriteNode alloc]initWithTexture:[[TextureList sharedManager]returnGradientofSize:[[TextureList sharedManager]returnTextureSize:kGMHUDFlowerTarget] topColor:[CIColor colorWithRed:255.0/255.0 green:171.0/255.0 blue:121.0/255.0] bottomColor:[CIColor colorWithRed:225.0/255.0 green:57.0/255.0 blue:86.0/255.0]] color:[UIColor orangeColor] size:CGSizeMake(0, self.frame.size.height)];
            animatedGraphic.anchorPoint = CGPointMake(0, 0.5);
            animatedGraphic.zPosition = self.zPosition+1;
            [self addChild:animatedGraphic];

使用渐变来表示sktexture的代码：

-(SKTexture*)returnHorizontalGradientofSize:(CGSize)size
                                  leftColor:(CIColor*)leftColor
                                 rightColor:(CIColor*)rightColor{

    CIContext *coreImageContext = [CIContext contextWithOptions:nil];
    CIFilter *gradientFilter = [CIFilter filterWithName:@"CILinearGradient"];
    [gradientFilter setDefaults];
    CIVector *startVector = [CIVector vectorWithX:0 Y:size.height/2];
    CIVector *endVector = [CIVector vectorWithX:size.width Y:size.height/2];
    [gradientFilter setValue:startVector forKey:@"inputPoint0"];
    [gradientFilter setValue:endVector forKey:@"inputPoint1"];
    [gradientFilter setValue:leftColor forKey:@"inputColor0"];
    [gradientFilter setValue:rightColor forKey:@"inputColor1"];
    CGImageRef cgimg = [coreImageContext createCGImage:[gradientFilter outputImage]
                                              fromRect:CGRectMake(0, 0, size.width, size.height)];
    UIImage *theImage = [UIImage imageWithCGImage:cgimg];
    CFRelease(cgimg);
    return [SKTexture textureWithImage:theImage];
}

这对于AGSpriteButton类来说是一个问题，它占用了内存，因此在加载广告时最终导致崩溃，你可以在这里找到修复：
