【问题描述】：

我正在按照 Parse 教程为我的设备配置推送通知。

https://www.parse.com/tutorials/ios-push-notifications

我的苹果开发者屏幕显示它们已启用：

我已经安装了推送证书：

我已将 .p12 证书添加到 Parse 的设置部分：

我已将请求的代码添加到我的 appdelegate：

    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
    PFPush.handlePush(userInfo)


func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
    installation.saveInBackground()


/** Get the availability to use the GPS at any given time */
func availabile() -> Bool 
    return !(locationServices.getGlobalManager().location == nil)


  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
    // Override point for customization after application launch.
    Parse.setApplicationId("<redacted>",  clientKey:"<redacted>")


    let userNotificationTypes = (UIUserNotificationType.Alert |
        UIUserNotificationType.Badge |
        UIUserNotificationType.Sound);

    let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    GMSServices.provideAPIKey(GoogleAPIKey.apiKey());

    locationServices.resolveLocationServices 
        success in
        if success 
            println("Location services success - \(self)")
        
        else 
            println("Locations services not allowed - \(self)")
        
    

    return true

当我尝试发送测试推送通知（我的应用程序在我的 iPhone 6+ 上运行）时，我收到没有设备注册的消息。我相信我已经正确地遵循了每一步，但我在这里不知所措。

【参考方案1】：

application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()

问题是，您尝试注册远程通知的时间过早，即您应该在用户允许您的应用接收通知后注册通知。你可以在 app delegate 的 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings; 方法中了解到这一点。只需在 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings 方法中执行 application.registerForRemoteNotifications() 即可，一切正常。祝你好运！

【讨论】：

我没有 - (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings 方法。你能告诉我这个方法应该是什么样子吗？

看看UIApplicationDelegate 协议文档，它就在那里。请注意，它仅适用于 iOS8 及更高版本。
