iOS 应用程序仅在 TestFlight 构建时崩溃

Question

我有一个 Swift 中的 ios 应用程序。该应用程序运行良好，并且从 xcode 本地上传时不会崩溃。但从 testflight 上传时该应用程序崩溃了。我发现代码没有任何问题。我已经在我的应用程序中实现了 Crashlytics，它给出了以下报告。

我不明白这份报告中的任何内容，如果有人知道请帮助我。

这里是viewDidload

  override func viewDidLoad() {
    super.viewDidLoad()
     Giving instance of HomeViewController to AppDelegate
      let appDele = UIApplication.shared.delegate as! AppDelegate
      appDele.homeVC = self
    token = FIRInstanceID.instanceID().token()!
//Method to handle Firebase token  
    UserDefaults.standard.set(token, forKey: "Notificationtoken")
    print("@@@@@@@@@@@@@@@@@@@@@@@ token provided is \(String(describing: token))")
     let tokenstr = UserDefaults.standard.value(forKey: "Notificationtoken") as! String
    if(token == tokenstr){
        handleFCMToken(token: tokenstr)
    }
    else{
        handleFCMToken(token: token!)

    }

    setUpNavBar()
    setPopUpImage()
    setUpcarousel()
    setUpDelegates()
    let help = Helper()

    help.setUpGoogleAnalytics(screenName: "Home")

    self.presenter = HomeViewPresenter(homeView: self)
    presenter.getCarousel()
    if(showProfile){
        ProfileClicked()
    }
    // Do any additional setup after loading the view.
}

这是 viewWillAppear

 override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    setUpUI()


}

setupUI及方法

 func setUpUI(){
    let wholesaler:Wholesaler = Helper.getWsProfile()

    DispatchQueue.main.async {
        self.wholesalerName.text = "Hello, \(wholesaler.wholesaler_name)"
        self.pdsPoints.text = "\(wholesaler.pdsPoints!)"
        self.visibilityPoints.text = "\(wholesaler.visibilityPoins!)"
    }
    iconNameString = ["SMS","Customer\n Groups","Visibility\n Contest","My\n Earnings","\(wholesaler.lastSchemeMonth!)\n Schemes","App\n News", "", "Contact\n Us"]

}

Answer 1

我认为查看 HomeViewController 的一些代码会给我们带来更多的见解。

但这里有一些评论:

• 不确定完整的堆栈，但由于某种原因在 viewDidLoad 之前调用 viewWillAppear 似乎很奇怪。您是否在相应的方法上正确调用了 super ？
• 您是否尝试过在 Release模式和 Debug模式下使用工具来分析应用程序？您可以在架构设置中对此进行管理。
• 另一个提示是优化级别，但我认为它对于您的场景来说有点先进。转到您的目标设置并搜索优化级别，您会注意到它对于调试和发布是不同的。有时具有多个 block 和/或线程的复杂算法可能会受此影响。
