应用审核团队遇到了EXC_BREAKPOINT（SIGTRAP）错误，但无法复现。

iosswiftswift2crash-reports
21

因为我的App（iOS，Swift 2.2，Xcode 7.3）在启动时崩溃，所以Beta App Review团队拒绝了它。

更新：从App Review团队得到答复……它只在iPad上崩溃，而不是在iPhone上。

问题是我无法重现这个崩溃。即使在我的三个物理设备上进行测试（iPhone 4S、iPhone6和iPad Air），也没有出现崩溃情况，这些设备均进行了干净安装或通过TestFlight内部测试进行了更新（因此与App Review Team正在审核的完全相同的构建和存档）。

崩溃日志摘录（从App Review团队收到）（已符号化）：

MapViewController是UINavigationController的rootViewController，第210行包含：self.view.backgroundColor = UIColor.blackColor()

更新： 删除了该行并提交了另一个构建版本。出现了相同的崩溃日志，现在在下一行崩溃：imageview.hidden = true

尝试在设备上直接从Xcode中以“Release”配置运行，希望它会崩溃并指向我正确的方向，但是没有崩溃 :-/ 还有非常有趣的是，在同一应用程序的先前版本中也有相同的问题（也被拒绝）。我向审查团队发送了类似于这个故事的回复，他们批准了它进行外部测试（没有任何更改）。我的beta测试者中只有一个人（大约300个）报告了类似的启动崩溃。

在Sigtrap断点上做了很多谷歌搜索，但没有找到类似于我正在经历的情况。所以，我真的很迷茫。我无法重现它，崩溃日志也没有指导我可以调查的方向。

更新：这是我从App Review Team获得的完整（符号化）崩溃报告（不包括二进制图像，那里看起来都很好）。也许其中的某些内容（其他线程？）会为某人敲响警钟。任何帮助或建议将不胜感激。

编辑 如一些人在评论中所问，这里是我AppDelegate的didFinishLaunchingWithOptions和我的rootVC的viewDidLoad的代码。正如我提到的，我不认为是我的viewDidLoad中的任何内容，因为它总是在viewDidLoad的第一行崩溃。我猜想可能是我的AppDel中的某些内容或者是全局的某些东西...也就是在我的rootVC的viewDidLoad之前执行的。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {

他们说它在启动时“崩溃了”。奇怪的是，他们崩溃报告中的“硬件型号”是xxx，而通常是iPhone7,2或iPad 4,2等。我猜他们可能有某种自动化测试设置，可以同时在多个设备（或模拟器？？？）上运行应用程序。我问过他们xxx代表什么......但还没有回复。 - guido
你的代码段显示在第210行，但苹果崩溃日志显示在第216行。这两个位置上都有什么内容？ - Siriss
抱歉，Siriss。上面的崩溃报告摘录是我提交的初始版本。在第210行是self.view.backgroundColor = UIColor.blackColor()，完整的崩溃日志是从第二个版本开始的（我删除了210），然后它在下一行（216）崩溃，即image view.hidden = true。在两种情况下，都是viewDidLoad的第一行。这让我想到它不是在那个视图控制器中，而是可能在其他地方（应用程序委托或全局）。 - guido
@RJE，是的，我已经尝试在发布配置中运行了。没有崩溃。也试过在调试器中启用所有异常，但在我的设备上运行时没有抛出任何异常。（这也在debug和config中尝试过） - guido
@RJE...正是您的评论让我再次检查我是否在强制解包可选项。如果您想要这份赏金，请发布一个答案，我会分配给您！谢谢！ - guido

哈哈，

--@RJE... 是你的评论让我再次检查是否强制解包了可选项。如果你想要这个奖励，发表一个答案，我会把它分配给你！谢谢！- guido 5小时前--

奖赏总是很重要的，

无论如何，很重要的是要知道SIGTRAP的意思。它基本上是一个运行时异常而不是错误。因此，如果您无法真正找到问题所在，您必须检查是否有任何可能引起异常的地方。（特别是使用Swift可选类型）

通常情况下，它可能是数组索引越界、强制解包nil或类似的任何事情。此外，如果它只在某些设备上偶尔发生或仅在某些设备上发生，则可能由于UI动画的各种延迟而出现问题。（例如presentViewController withAnimation并在其完成之前尝试某些内容。）

但是，老实说，我没有看到您原始代码中的任何问题。它不应该崩溃。

除非Storyboard的初始点是UINavigationController，而您忘记将其类设置为CustomNavigationController。然后它将在以下代码中崩溃。（这在Swift中是预期的。）

let navController = window!.rootViewController as! CustomNavigationController

但我认为这不是问题所在。因为应该在任何设备上每次都会崩溃。

而且在applicationDidBecomeActive被调用时，窗口不会为空。所以可能是在此之后你对navController做了其他操作。

或者苹果的审核团队在一个有故障的设备上测试了你的应用程序 :)

嗨。你找到任何解决方案或其他东西了吗？我有同样的问题，苹果已经拒绝了我的应用程序。 - Mehul Sojitra

我已经获得批准。

更新

虽然我已经获得了批准，但是应用程序的下一个版本再次被拒绝，原因相同，崩溃报告也相同，仍然指向viewDidLoad方法的第一行。

然后我将所有的代码从viewDidLoad中彻底移动到了viewWillAppear中，如下：

var viewLoaded = false

override func viewDidLoad() {
    super.viewDidLoad()
    // Do nothing
}

override func viewWillAppear(animated: Bool) {
    if !viewLoaded {

        // viewDidLoad code

        viewLoaded = true
    }

    // viewWillAppear code

}

我的理论是我发现了一个苹果的Bug：

我正在使用故事板，我的rootViewController非常（非常）重。有许多UIVIews、UILabels、MapView、Buttons、Searcher、嵌入式TableView等。我猜测它崩溃是因为在调用viewDidLoad时，并没有初始化所有的storyboard元素。

如果这确实是真的（时间会告诉我们当我提交更多版本进行审核时），我认为我要么发现了iOS中的一个bug（因为我应该能够从storyboard中引用IBOutlets在我的viewDidLoad中），要么是审核过程与实际设备运行应用程序存在差异（因为我和我的400个Beta测试人员都没有遇到这种崩溃）。

更新结束

根据RJE的评论，我再次查看了我的AppDelegate，看看是否强制解包了某些内容。我确实这样做了，但据我所知，这些值永远不可能为空，所以当我第一次编写代码时，我没有再考虑它。我想我应该考虑一下。

在最终获得批准的构建中，与之前未获批准的构建有3个不同之处。

  1. 在我的AppDelegate的didFinishLaunchingWithOptions中，我强制解包了NSBundle.mainBundle().infoDictionary!["CFBundleVersion"]!

我做出了改变。

if UD.appVersion == nil || UD.appVersion != "\(NSBundle.mainBundle().infoDictionary!["CFBundleVersion"]!)" {
    startClean()
    UD.appVersion = "\(NSBundle.mainBundle().infoDictionary!["CFBundleVersion"]!)"
}

转换为这样

var versionInInfoDictionary = "dummy"
if let infoDict = NSBundle.mainBundle().infoDictionary {
    if let bundleVersion = infoDict["CFBundleVersion"] as? String{
        versionInInfoDictionary = bundleVersion
    }
    else {
        printError("bundleVersion nil")
    }
}
else {
    printError("infoDic nil")
}

if UD.appVersion == nil || UD.appVersion != versionInInfoDictionary {
    startClean()
    UD.appVersion = versionInInfoDictionary
}
  1. 在我的AppDelegate的applicationDidBecomeActive中，我强制解包了window（在我的AppDelegate类中定义为var window：UIWindow？）

我改为：

func applicationDidBecomeActive(application: UIApplication) {

    // some code

    let navController = window!.rootViewController as! CustomNavigationController

    // some code
}

转换为此

func applicationDidBecomeActive(application: UIApplication) {

    // some code
    self.continueDidBecomeActive()
}

func continueDidBecomeActive() {
    guard window != nil else {
        printError("Window still nil")
        NSTimer.scheduledTimerWithTimeInterval(0.3, target: self, selector: #selector(AppDelegate.continueDidBecomeActive), userInfo: nil, repeats: false)
        return
    }
    if let navController = window!.rootViewController as? CustomNavigationController {

        // some code

    }
}

在我的构建设置中，最后我将'Release'的代码签名身份设置为 iOS Developer。我把它改成了iOS Distribution。
现在，我认为并不是第3点导致我的应用程序在App审核团队中崩溃，否则它会在所有设备上甚至在我的设备上都崩溃。
所以，这必须是第1点、第2点或两者的原因。说实话我并不知道，我仍然有些困惑，为什么在任何情况下这些值都会为空。如果有更多见解……我很愿意听取您的意见。
你是否发现在视图准备好之前就调用了ViewDidLoad方法？我的意思是，Storyboard代码应该在loadView期间调用，这应该保证在ViewDidLoad之前发生，对吧？它们都发生在串行的主线程上。 - Developer Sheldon
我用不同的方法解决了它，决定不深入探究苹果雷达兔洞。 - guido

我曾经遇到过类似的问题。我的测试设备没有崩溃，但是苹果公司却无法启动应用程序。

我在解决方案中心向审核团队发送了消息。他们重新开始了审核流程，但无法重现崩溃。最终，我的应用程序被接受了 :)
