Sprite Kit应用程序中的内存泄漏 [英] Memory Leak in Sprite Kit Application

问题描述

我有一个我在Xcode 5中创建的Sprite Kit游戏，当使用Instruments对其进行泄漏分析时，我发现确实存在一些泄漏：

I have a Sprite Kit game that I created in Xcode 5 and when profiling it for leaks using Instruments I see that there are indeed some leaks:

问题是我不能告诉我来自我的应用程序的位置，因为负责框架栏目没有指向我的应用程序中的任何位置。

The problem is that I can't tell where in my application this is coming from as the "Responsible Frame" column doesn't point me to anywhere in my application.

如何进行调试/跟踪这个问题的根源？

How would one go about debugging/tracking the origins of this issue?

更新＃1

只有一个我正在与CGPath进行交互的文件，但我正在调用 CGPathRelease

There is only one file in which I'm interacting w/ CGPath but I am calling CGPathRelease

...
CGMutablePathRef path = CGPathCreateMutable();

CGPathMoveToPoint(path, NULL, 0, 0);
CGPathAddLineToPoint(path, NULL, size.width, 0);
CGPathAddLineToPoint(path, NULL, size.width, (upperCount * size.width));
CGPathAddLineToPoint(path, NULL, 0, (upperCount * size.width));

CGPathCloseSubpath(path);

upper.physicsBody = [SKPhysicsBody bodyWithPolygonFromPath:path];

CGPathRelease(path);
...        

更新＃2

切换打开仪器右侧面板后，我能够看到有问题的线条（虽然我仍然不确定这里是不是错误）：

After toggling open the right panel in Instruments I was able to see the offending lines (although I'm still not sure is wrong here):

第一组泄漏...

The first set of leaks...

第二组泄漏...

The second set of leaks...

推荐答案

你见过这个吗？ SKPhysicsBody bodyWithPolygonFromPath内存泄漏

看起来喜欢它在SKPhysicsBody中的一个spritekit错误（我猜它会保留在bodyWithPolygonFromPath中但是没有发布）。

Looks like its a spritekit bug in SKPhysicsBody (I would guess it is being retained within bodyWithPolygonFromPath but not released).
