我在现有项目中面临一个奇怪的问题。
从早上开始，我正面临着一次火警事故。
它工作正常，没有任何问题，但是从早上开始，我面临这个问题。
崩溃:
***由于未捕获的异常“NSInternalInconsistencyException”而终止应用程序，原因:“默认FIRApp
必须先配置实例，然后才能设置默认FIRAuthinstance
初始化。一种确保方法是调用[FIRApp configure]; (Swift中的FirebaseApp.configure())在应用程序委托的
application:didFinishLaunchingWithOptions: (在Swift中为application(_:didFinishLaunchingWithOptions:))。
它清楚地表明，我需要在我的应用程序委托中实现FirebaseApp.configure()，并且自最近六个月以来就已经存在。
AppDelegate代码:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
Messaging.messaging().delegate = self as? MessagingDelegate
self.getRegisterForRemoteNotifications(application)
return true
}
你们可以看到在
didFinishLaunchingWithOptions中已经调用的Firebase配置在应用启动时仍然面临崩溃问题。而且我观察到我的appdelegate
didFinishLaunchingWithOptions方法未调用，并且崩溃了我的应用程序。编辑:
ViewController代码:
var authUI: FUIAuth!
override func viewDidLoad() {
super.viewDidLoad()
authUI = FUIAuth.defaultAuthUI()
authUI?.delegate = self
if authUI.auth?.currentUser != nil {
self.checkAdminUser()
self.getFavPlace()
}
}

任何帮助或指导，不胜感激!
最佳答案
最后，我找到了为什么我的应用程序崩溃而没有调用appDidFinshLaunching()的原因。
这是由于TabViewController之一试图从应用程序委托调用FirebaseApp.configure()之前获取当前用户详细信息。
其直接定义如下。
let user = FIRAuth().auth.currentUser
因此，它崩溃了。
我将其放在
viewDidLoad()方法下，现在该应用程序运行正常，没有崩溃。感谢每个人的快速答复，并为此提供指导。
希望此信息对其他人有帮助!
关于ios - 应用程序在加载时崩溃，根本不调用`didFinishLaunchingWithOptions`，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/60212857/
