我已经使用GCM很长时间了。有一天，它突然破裂了。问题是我发送的第一个推送获得了成功状态，但该应用程序未收到任何推送。我发送的第二次推送失败，并显示NotRegistered错误。我重新安装该应用程序：成功（未收到通知），失败（未注册）->循环。我不知道发生了什么变化。Google支持非常无助，需要花费大量时间来回答简单的问题，无论是GCM问题，APNs问题还是客户问题。如果以前有人遇到过此类问题，请让我知道要查找的内容。看起来是这样的：

我怀疑这是在更新到iOS 9之后发生的。但是我不确定。如果新iOS中有可能阻止GCM的东西，请有人指出。

那家伙也有类似的问题。问题出在某些清单文件上。我需要为iOS 9添加一些条目以允许GCM的Info.plist中吗？

更新：

每次应用启动时都会调用onTokenRefresh。不过，我又得到了相同的令牌。我怀疑GCM服务器上的令牌有问题。

GCM委派代码：

var connectedToGCM = false


private var deviceToken: NSData?

var gcmSenderID: String!
let authorizedEntity = "my GCM Sender_ID"


public func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Override point for customization after application launch.
    var configureError:NSError?
    GGLContext.sharedInstance().configureWithError(&configureError)
    assert(configureError == nil, "Error configuring Google services: \(configureError)")
    gcmSenderID = GGLContext.sharedInstance().configuration.gcmSenderID
    // [END_EXCLUDE]
    // Register for remote notifications
    if #available(iOS 8.0, *) {
        let settings: UIUserNotificationSettings =
        UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    } else {
        // Fallback
        let types: UIRemoteNotificationType = [.Alert, .Badge, .Sound]
        application.registerForRemoteNotificationTypes(types)
    }

    // [END register_for_remote_notifications]
    // [START start_gcm_service]
    let gcmConfig = GCMConfig.defaultConfig()
    GCMService.sharedInstance().startWithConfig(gcmConfig)

    return true
}

public func onTokenRefresh() {
    print("Token needs to be refreshed!")
    let options = [
        kGGLInstanceIDRegisterAPNSOption : deviceToken!,
        kGGLInstanceIDAPNSServerTypeSandboxOption : true
    ]
           GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(authorizedEntity, scope: kGGLInstanceIDScopeGCM, options: options) { (token, error) -> Void in
        if error != nil {
            print("Error: \(error.localizedDescription)")
        } else {
            print("Token: \(token)")
        }
    }
}


public func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)

    instanceIDConfig.delegate = self
    // Start the GGLInstanceID shared instance with that config and request a registration
    // token to enable reception of notifications
    GGLInstanceID.sharedInstance().startWithConfig(instanceIDConfig)
    self.deviceToken = deviceToken

    GCMService.sharedInstance().disconnect()
    connectedToGCM = false
}

public func applicationDidBecomeActive( application: UIApplication) {
    print("App became active")
    UIApplication.sharedApplication().applicationIconBadgeNumber = 0
    // Connect to the GCM server to receive non-APNS notifications
    GCMService.sharedInstance().connectWithHandler({
        (NSError error) -> Void in
        if error != nil {
            print("Could not connect to GCM: \(error.localizedDescription)")
        } else {
            self.connectedToGCM = true
            print("Connected to GCM")
            // ...
        }
    })
}

public func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    print("Notification received: \(userInfo)")
    GCMService.sharedInstance().appDidReceiveMessage(userInfo)
}

public func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print("Error registering")
}

public func application( application: UIApplication,
    didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
    fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) {

        print("Notification received(background): \(userInfo)")

        NotificationManager.sharedInsteance().parseNotification(userInfo)

        // This works only if the app started the GCM service
        GCMService.sharedInstance().appDidReceiveMessage(userInfo);

        // Handle the received message
        // Invoke the completion handler passing the appropriate UIBackgroundFetchResult value
        // [START_EXCLUDE]
        handler(UIBackgroundFetchResult.NewData);
        // [END_EXCLUDE]
}

更新

OK，所以我相信我搞砸了.plist位置（由于某种原因它不在根目录中）。我移到了根目录，现在在启动GCM时收到此警告/错误：

UPD。好的，它实际上只发生了一次并停止了。所以我不认为问题出在这里。

在将.plist移到根目录后，onTokenRefresh（）调用停止了，但是我仍然没有注册。
