虽然不支持SceneDelegate，但未调用AppDelegate方法

Question

在我的支持iOS 11到iOS 13的应用中，我遇到了一个大问题。我的大多数appDelegate方法都不再被调用（例如didFinishLaunchingWithOptions：applicationDidEnterBackground或applicationDidBecomeActive除外）。但是，我读了this post，但我既不支持iPad，也不支持多个窗口，我没有/使用SceneDelegate，并且我的info.plist文件中也没有任何“应用程序场景清单”。还有其他要做的事情来检索AppDelegate的正常行为吗？谢谢！

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

// Still called, app launches UI normally.
    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        self.window = UIWindow(frame: UIScreen.main.bounds)
        self.window?.rootViewController = LoadingViewController.instantiate()
        self.window?.makeKeyAndVisible()
        return true 
    }

// Not called anymore 
    func applicationWillResignActive(_ application: UIApplication) {
        log.verbose("applicationWillResignActive") 
    }

// Not called anymore   
    func applicationDidEnterBackground(_ application: UIApplication) {
        log.verbose("applicationDidEnterBackground")
        RideController.shared.prepareForBackground() 
    }

// Not called anymore  
    func applicationWillEnterForeground(_ application: UIApplication) {
        log.verbose("applicationWillEnterForeground") 
    }

// Not called anymore
    func applicationDidBecomeActive(_ application: UIApplication) {
        log.verbose("applicationDidBecomeActive")
        RideController.shared.prepareForForeground() // Not called anymore
        // Watch
        WatchController.shared.startSession() 
    }

    func applicationWillTerminate(_ application: UIApplication) {
        log.verbose("applicationWillTerminate")
        RideController.shared.prepareForBackground()
    }

}

哇！我发现了错误。我在应用程序中使用Pod Firebase，并且显然Firebase Cloud Messaging服务（FCM）在启动时使应用程序委托蒙上了阴影。我必须在我的info.plist文件中将此键FirebaseAppDelegateProxyEnabled设置为NO才能对其进行修复。
