在app delegate

Question

我的应用程序需要入门，我想等到用户到达AskForVOIPNotificationsViewController之后才能请求获得推送/ voip通知的权限。下面的代码有点工作，问题是AppDelegate中的pushRegistry没有意识到它有权限并且AppDelegate中的didUpdatePushCredentials没有被调用。代码永远不会运行，服务器永远不会获取设备令牌。但是，如果我关闭应用程序并重新启动，则会调用didUpdatePushCredentials，服务器将获取令牌，并且用户可以接收通知。

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，但我无法使用PushKit。

非常感谢任何帮助 - 谢谢！

  

在AskForVOIPNotificationsViewController

中

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)
    }
}

  

在App代理

中

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，我希望这也适合你。

仍然不是一个好主意，这个东西必须在appdelegate。

    return true
}

有一个快乐的编码。

根据您发布的代码，您似乎唯一可以拨打registerForVoIPPushes()的地方位于application(_:didFinishLaunchingWithOptions:)

由于registerForVoIPPushes()设置了voip注册表委托，因此您应该在用户授予通知权限时调用它。

根据this tutorial，registerUserNotificationSettings(userNotificationSettings)有一个代表回调application(_:didRegisterWithNotificationSettings:)，您可以将其用于此目的：

func application(application: UIApplication, didRegisterUserNotifications notificationSettings: UIUserNotificationSettings)
{
    // Check whether notifications are permitted
    if notificationSettings != .None
    {
        print("Permission for notifications granted.")
        registerForVoIPPushes()
    }
}
