.showsPhysics的内存泄漏 [英] Memory Leak for .showsPhysics

问题描述

我刚刚花了最近5个小时尝试在我的Spritekit App中调试内存泄漏。

I have just recently spent the past 5 hours trying to debug a memory leak in my Spritekit App.

应用启动后，我注意到我的记忆中有一小段爬升用法。

After app Launch, I noticed a small climb in my memory usage.

我花了5个小时中的3个时间挖掘参考资料，用 ARC （绝对推荐读一下像我这样的中间人）

I spent 3 of those 5 hours digging through reference material, learning about strong VS Weak with ARC (Definitely Recommend Reading up on that for Intermediates Such as myself)

还有其他人遇到过这个问题吗？如果有的话有什么解释吗？这是我的GameViewController的一小部分：

Is anyone else experiencing this issue? If so is there any sort of explanation? Here is a small snippet of my GameViewController:

class GameViewController: UIViewController {

override func viewDidLoad() {
    super.viewDidLoad()

    if let scene = MainMenu(fileNamed:"MainMenu") {
        // Configure the view.
        let skView = self.view as! SKView
        skView.showsFPS = true
        skView.showsNodeCount = true
        skView.multipleTouchEnabled = true
        skView.showsPhysics = true

        /* Sprite Kit applies additional optimizations to improve rendering performance */
        skView.ignoresSiblingOrder = true

        /* Set the scale mode to scale to fit the window */
        scene.scaleMode = .Fill

        //var GameSaveData = GameData()

        // Scene Config
        //scene.Landscape = "Test_Landscape"
        //scene.Area = "Start"

        skView.presentScene(scene)
    }else{

        print("Couldn't Load Game Scene")
    }
}

正如你所看到的，我在这里并没有做任何与众不同的事情。我会发布我的gamecene代码，但在我仍在观察内存泄漏的时候，它都被注释掉了。

As you can see, I'm not doing anything out of the ordinary here. I would Post my gamescene code, but it was all commented out at the time I was still observing the memory leak.

推荐答案

最终出于苛刻，我刚开始评论代码行，然后构建和分析，直到内存泄漏得到解决。

Eventually, out of fustration, I just started commenting lines of code, then building and profiling until the memory leak was solved.

在我的GameViewController.swift文件中，

Turns out in my GameViewController.swift file,

skView.showsPhysics = true

是罪魁祸首。这有点像一个新的错误，因为我在<中没有看到这个问题。 IOS 9.2

was the culprit. This must be somewhat of a new bug seeing as how I haven't seen this issue in < IOS 9.2
