应用程序在Ios 我的应用程序在iPhone上运行时崩溃，但在模拟器中没有。我可以使用哪些调试技术来解决这个问题？,ios,iphone,xcode,swift,debugging,Ios,Iphone,Xcode,Swift,Debugging,应用程序在GameViewController中的viewDidLoad的右括号上崩溃。我的viewDidLoad代码如下所示： override func viewDidLoad() { super.viewDidLoad() let scene = GameScene(size: CGSize(width: 768, height: 1024)) let skView = self.view as! SKView skView.showsFields = t
GameViewControllerviewDidLoadviewDidLoadoverride func viewDidLoad() {
super.viewDidLoad()
let scene = GameScene(size: CGSize(width: 768, height: 1024))
let skView = self.view as! SKView
skView.showsFields = true
skView.ignoresSiblingOrder = true
skView.showsPhysics = true
scene.scaleMode = .AspectFill
skView.presentScene(scene)
}
游戏场景的行，那么应用程序运行良好（在本例中，它基本上是一个空白视图）。这告诉我，在我的游戏场景
类中显然发生了一些事情，但我不能确切地知道是什么
当我运行回溯跟踪时，我得到：

但不幸的是，我不知道从这里走到哪里。我真的不知道如何破译回溯。我知道我的游戏场景类有问题，有没有办法弄清楚到底是什么？还是我必须单独测试每个属性
除此之外，当我没有在调试器中运行应用程序时，它在我的iPhone上运行良好
编辑：问题已解决。这显然是Xcode的一个bug，而不是我的任何代码 事实证明，这是一个带有xcode的bug，而不是任何代码，如本问题所示：
显然，EagleContext_renderBufferStorage可能会在iOS 8.3+上导致错误。解决方案是更改用于禁用GPU帧捕获的方案。不完全确定为什么会这样，但确实如此 我见过类似的事情发生在那些错误地将他们的资源包括在项目中的人身上。调试器可以访问不一定打包并发送到手机的文件。也许项目中没有正确包含精灵表？
