ios - 在应用程序委托(delegate)之外注册 voip 通知

Question

我的应用程序需要登录，我想等到用户到达 AskForVOIPNotificationsViewController 后再请求呈现推送/VoIP 通知的权限。下面的代码可以工作，问题是 AppDelegate 中的 pushRegistry 没有意识到它具有权限，并且 AppDelegate 中的 didUpdatePushCredentials 没有被调用。该代码永远不会运行，服务器也永远不会获取设备 token 。但是，如果我关闭应用程序并重新启动，则会调用 didUpdatePushCredentials，服务器会获取 token 并且用户能够接收通知。

如何确保从 AskForVOIPNotificationsViewController 调用 didUpdatePushCredentials/PKPushRegistry，以便用户能够立即接收 voip 通知而无需重新启动应用程序？

我根据类似的 question 实现了我的代码，但我无法让它与 PushKit 一起使用。

非常感谢任何帮助 - 谢谢!

In AskForVOIPNotificationsViewController

func registerForNotifications() {
    let notificationSettings: UIUserNotificationSettings! = UIApplication.sharedApplication().currentUserNotificationSettings()
    if !notificationSettings.types.contains([.Badge, .Sound, .Alert])  {
        let notificationTypes: UIUserNotificationType = [.Badge, .Sound, .Alert]
        let notificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
    }
}

In App delegate

import UIKit
import PushKit

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, PKPushRegistryDelegate {

    var voipRegistry:PKPushRegistry!
    var window: UIWindow?



    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

        registerForVoIPPushes()
        return true
    }


    func registerForVoIPPushes() {
        voipRegistry = PKPushRegistry(queue: dispatch_get_main_queue())
        voipRegistry.delegate = self
        voipRegistry.desiredPushTypes = Set([PKPushTypeVoIP])
        print("VOIP Push registered")
    }


    func pushRegistry(registry: PKPushRegistry!, didUpdatePushCredentials credentials: PKPushCredentials!, forType type: String!) {

        let voipToken: String! = credentials.token.description

         print("\n\n##### didUpdatePushCredentials: \n\n", voipToken)

        **// update server with device token HERE**

    }


    func pushRegistry(registry: PKPushRegistry!, didReceiveIncomingPushWithPayload payload: PKPushPayload!, forType type: String!) {

        print("\n\n##  DID RECEIVE NOTIFICATION ## \n\n")
        let data = payload.dictionaryPayload
        let aps = data["aps"] as! [String: AnyObject]
        let alert = aps["alert"] as! [String: AnyObject]
        let localNotification = UILocalNotification()

        //setup the notification
        localNotification.alertBody = alert["body"] as? String
        localNotification.alertTitle = alert["title"] as? String
        localNotification.soundName = "Simple_ring_tone_29s.aiff"
        localNotification.alertAction = alert["action-loc-key"] as? String

        UIApplication.sharedApplication().applicationIconBadgeNumber = 1

         //show the notification
        UIApplication.sharedApplication().presentLocalNotificationNow(localNotification)

    }

这对我有用，我希望对你也有用。

但这仍然不是一个好主意，这些东西必须在 appdelegate 中。

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

           
    let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
    application.registerForRemoteNotificationTypes(types)
