从 AppStore 或 TestFlight 启动时应用程序崩溃但在其他地方运行良好

App crashing when launching from AppStore or TestFlight but working fine elseways

我的申请更新被拒绝了。在拒绝邮件中,他们写了 "Application crashes at launch"。然后我尝试了我的应用程序,但无法使其崩溃。所以我使用了 TestFlight 并注意到当我从 TestFlight 或 AppStore 启动我的应用程序时,它在启动时崩溃了。但是,如果我正常启动我的应用程序,它确实可以正常运行而不会出现任何崩溃。问题是这个错误发生在 iOS 10 更新之后。现在我的商店应用程序在从 AppStore 启动时也崩溃了,而它在 2 周前运行良好。

Apple 向我发送了崩溃日志:

还有 4 个线程,但这个线程崩溃了,所以我没有复制其余线程。我做了一些研究,尽管我确实注意到我的崩溃日志没有完全翻译(出于某种奇怪的原因,因为我有所有 dsyms 但无论如何),我确实设法理解我在第 217 行崩溃(告诉我我是否'我错了)。我知道 SIGTRAP 大部分时间都会抛出 NSExceptions。该行本身是:

let api = MyAppAPI.instance

实例是单例。我的猜测是实例创建失败了。这是代码:

static var instance: MyAppAPI = {
    return Singleton.instance
}()

class MyAppAPI: Manager {
struct Singleton {
    static var configuration: NSURLSessionConfiguration = {
        var configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        let version = NSBundle.mainBundle().objectForInfoDictionaryKey("CFBundleShortVersionString") as? String ?? ""
        configuration.HTTPAdditionalHeaders = [
            "Accept": "application/vnd.MyApp.api+json, application/json;q=0.9",
            "User-Agent": "MyApp iOS/\(version)",
            "X-API-Version": "1.0.1"
        ]

        return configuration
        }()

    static var instance = MyAppAPI(configuration: configuration)
    static var baseURL : NSURL! = nil
}

我对这个错误非常绝望,我确实尝试了一些没有成功的事情。我在寻找正确的地方吗?有没有人有解决方案?任何形式的帮助将不胜感激。我愿意送给任何能为我找到解决方案或帮助我找到解决方案的人!

我找到了问题的解决方案。

不出所料,它来自 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool

在我的函数中 let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as! NSDictionary

我改成了let userInfo = launchOpts[UIApplicationLaunchOptionsRemoteNotificationKey] as? NSDictionary然后勾选了if userInfo != nil把所有的代码运行userInfo都打进了括号

如果它对任何人有帮助或者如果任何人正在为这个问题而苦苦挣扎,请检查你所有的 ! 并在需要时将它们交换到 ?(在 didFinishLaunchingWithOptions 上),因为从 TestFlight/AppStore 似乎有与已安装应用程序不同的选项(只是猜测,还不够专业)。
