iOS App Store 应用在登录期间崩溃未开发

如何解决iOS App Store 应用在登录期间崩溃未开发

所以这可能是因为 UserDefaults 在一段时间后被重置，也许是因为我经常更新操作系统，但是一段时间后我的 iOS 应用程序的发布版本会在我的登录屏幕上崩溃，可能是我检查的地方用于保存的凭据（在 UserDefaults 中）。重新安装应用程序可以解决问题。控制台返回很多：

不支持在主线程之外使用 UIKit 视图自定义 API。 -setAlignsToKeyboard: 发送到 <_uialertcontrollerview: layer="<CALayer:">>

我的系统日志在此线程上显示错误：

异常类型：EXC_CRASH (SIGABRT) 异常代码：0x0000000000000000,0x0000000000000000 例外说明：EXC_CORPSE_NOTIFY 由线程触发：4

这是我用来检查保存的凭据的一些代码。在后端 API 中，我看不到任何登录尝试。如果有帮助，我可以在它崩溃之前的一瞬间看到这个视图控制器。不确定这是否排除了 viewdidload。

override func viewDidLoad() {
    super.viewDidLoad()
    addLoadingSpinner()
    bLogIn.titleLabel?.font = UIFont.setToVoiceLight()
    self.tfCustomerID.delegate = self
    self.tfUsername.delegate = self
    self.tfPassword.delegate = self
    tfUsername.keyboardType = .default
    tfPassword.textContentType = .password
    setupUI()
    if UserDefaults.standard.string(forKey: UserDefaultsKeys.session) != nil
        && UserDefaults.standard.string(forKey: UserDefaultsKeys.savedCred) == "True" {
        login_session = UserDefaults.standard.string(forKey: UserDefaultsKeys.session)!
        check_session()
    }
    else if UserDefaults.standard.string(forKey: UserDefaultsKeys.savedCred) == "True" &&
            UserDefaults.standard.string(forKey: UserDefaultsKeys.usesBiometrics) == "True" {
        promptTouchOrFaceID()
    }
    removeLoadingSpinner()
}

override func viewWillAppear(_ animated: Bool) {
    AppDelegate.AppUtility.lockOrientation(UIInterfaceOrientationMask.portrait,andRotateTo:
                                            UIInterfaceOrientation.portrait)
    cbSave.isChecked = UserDefaults.standard.string(forKey: UserDefaultsKeys.savedCred) == "True"
    addObservers()
}

func check_session() {
    UserDefaults.standard.set(login_session,forKey: "session")
    UserInfo.access_token = UserDefaults.standard.string(forKey: "session")!

    var request = URLRequest(url: NSURL(string: checksession_url)! as URL)
    request.httpMethod = .GET
    request.addValues(...)
    let task = URLSession.shared.dataTask(with: request) { data,response,error in
        if let httpStatus = response as? HTTPURLResponse,httpStatus.statusCode == 200 {
            //VERIFIED THAT NEVER GETTING TO API
            DispatchQueue.main.async {
                ...
            }
        } else {
            self.promptTouchOrFaceID()
            UserDefaults.standard.set(nil,forKey: UserDefaultsKeys.session)
        }
    }
    task.resume()
}

这是我的生物识别提示代码：

func promptTouchOrFaceID() {
    //create context for touch auth
    let authenticationContext = LAContext()
    var error: NSError?
    authenticationContext.localizedFallbackTitle = ""
    let biometricType = authenticationContext.biometricType
    //check if the device has a fingerprint sensor,exit if not
    guard authenticationContext.canEvaluatePolicy(.deviceOwnerAuthenticationWithBiometrics,error: &error) else {
        let title = "Error"
        var message = ""
        switch biometricType {
        case .faceID:
            message = "This device does not have a FaceID sensor or the sensor is not enabled."
        case .touchID:
            message = "This device does not have a TouchID sensor or the sensor is not enabled."
        case .none:
            message = "This device does not have any sensors to use TouchID or FaceID"
        }

        AlertService.showAlert(on: self,title: title,message: message)
        UserDefaults.standard.set("False",forKey: UserDefaultsKeys.usesBiometrics)
        removeLoadingSpinner()
        return
    }
    authenticationContext.evaluatePolicy(.deviceOwnerAuthenticationWithBiometrics,localizedReason: "Please use your fingerprint to authenticate.",reply: { [unowned self] (success,error) -> Void in
                                            if (success) {
                                                //fingerprint recognized,set this possible and go to view controller
                                                OperationQueue.main.addOperation({ () -> Void in
                                                    self.fillInUserDetails()
                                                    self.login_now(
                                                        username:self.tfUsername.text!,password: self.userDefaults.string(forKey: UserDefaultsKeys.password)!,customer: self.tfCustomerID.text!)
                                                })
                                            }
                                         })

     }

解决方法

只是一个疯狂的镜头，但是您的 plist 文件中有 NSFaceIDUsageDescription 键吗？我记得几个月前遇到过这样的问题。
