如何提示用户接受AppDelegate之外的推送通知？

我的应用程序加载到视图控制器中，告诉用户为什么他们应该接受推送通知。直到他们按下此视图控制器上的继续按钮后，我才希望它们接受推送通知。这意味着我需要将代码包含在我的初始视图控制器中的某处，我们称之为BeforePromptController。我在使用Firebase以防万一。如何提示用户接受AppDelegate之外的推送通知？

这是我在AppDelegate中的工作代码（但是我想对其进行更改，以便在用户按下BeforePromptController中的Continue按钮后发生提示）。我试着只包含的AppDelegate这里的重要组成部分..

import UIKit 
import Firebase 
import FirebaseMessaging 
import UserNotifications 

@UIApplicationMain 
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, FIRMessagingDelegate { 

    var window: UIWindow? 

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 

     FIRApp.configure() 

     if #available(iOS 10.0, *) { 
      let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound] 
      UNUserNotificationCenter.current().requestAuthorization(
       options: authOptions, 
       completionHandler: {_, _ in }) 

      // For iOS 10 display notification (sent via APNS) 
      UNUserNotificationCenter.current().delegate = self 
      // For iOS 10 data message (sent via FCM) 
      FIRMessaging.messaging().remoteMessageDelegate = self 

     } else { 
      let settings: UIUserNotificationSettings = 
       UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil) 
      application.registerUserNotificationSettings(settings) 
     }   

     application.registerForRemoteNotifications() 

     return true 
    } 



    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) { 

     if application.applicationState == UIApplicationState.active { 

      var pushNotificationMessage = "" 
      if let aps = userInfo["aps"] as? NSDictionary { 
       if let alert = aps["alert"] as? NSDictionary { 
        if let message = alert["message"] as? NSString { 
         pushNotificationMessage = message as String 
        } 
       } else if let alert = aps["alert"] as? NSString { 
        pushNotificationMessage = alert as String 
       } 
      } 

      let notificationAlert = UIAlertController(title: nil, message: pushNotificationMessage, preferredStyle: .alert) 

      let defaultAction = UIAlertAction(title: "OK", style: .default, handler: { 
       (alert: UIAlertAction!) -> Void in 
      }) 
      defaultAction.setValue(Constants.activePushNotificationOKColor, forKey: "titleTextColor") 

      notificationAlert.addAction(defaultAction) 
      self.window?.rootViewController?.present(notificationAlert, animated: true, completion: nil) 
     } 
    } 
}

你可以只移动FIRApp.configure()，你需要问的授权后的代码;你可以得到应用与UIApplication.shared

有关推送通知，一旦你打电话application.registerForRemoteNotifications()会出现提示的引用，因此，在调用这个函数时，你想你会显示提示。

要访问您的UIApplication您可以在Swift2

使用Swift3 UIApplication.shared或 UIApplication.sharedApplication()
