【问题描述】：

我对 GCM 和 ios 推送通知有疑问。 应用程序连接到 GCM 并且一切正常，但是当我无法收到通知时。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
    let gcmSenderID = sharedUser.getGcmSenderId()
    if gcmSenderID?.characters.count > 0 
        var configureError:NSError?
        GGLContext.sharedInstance().configureWithError(&configureError)
        if configureError != nil 
            print("Error configuring the Google context: \(configureError)")
                
        let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 
    GGLInstanceID.sharedInstance().startWithConfig(GGLInstanceIDConfig.defaultConfig())
    registrationOptions = [kGGLInstanceIDRegisterAPNSOption:deviceToken,
        kGGLInstanceIDAPNSServerTypeSandboxOption:true]
    GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(gcmSenderID,
        scope: kGGLInstanceIDScopeGCM, options: registrationOptions, handler: registrationHandler)

func registrationHandler(registrationToken: String!, error: NSError!) 
    if (registrationToken != nil) 
        let params = [
            "reg_id": registrationToken,
            "dev_id": UIDevice.currentDevice().identifierForVendor!.UUIDString
        ]
        Alamofire.request(.POST, Config().gcmRegUrl, parameters: params, encoding: .JSON)
        print("Registred")
     else 
        print("Registration to GCM failed with error: \(error.localizedDescription)")
    

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject], fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) 
    print("Message")

这个didReceiveRemoteNotification 永远不会触发，我确信服务器会发送消息。

可能有什么问题？

【问题讨论】：

能否展示一下下游消息的结构？

消息是对象：collapseKey: "message", data: "msg": "text"

您是否设置了 to 或 registration_ids 字段？

@ArthurThompson 在服务器端是的，我向这个客户注册 ID 发送消息。

你在使用 GCMService.sharedInstance().connectWithHandler 吗？鉴于您使用的消息对象不会通过 APNS，您将需要它来接收非 APNS 消息。

【参考方案1】：

感谢Arthur Thompson，需要这个：

func applicationDidBecomeActive(application: UIApplication) 
    GCMService.sharedInstance().connectWithHandler(
        (NSError error) -> Void in
        if error != nil 
            print("Could not connect to GCM: \(error.localizedDescription)")
         else 
            print("Connected to GCM")
        
    )

我忘了：

GCMService.sharedInstance().startWithConfig(GCMConfig.defaultConfig())

添加didFinishLaunchingWithOptions。

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool 
    let gcmSenderID = sharedUser.getGcmSenderId()
    if gcmSenderID?.characters.count > 0 
        var configureError:NSError?
        GGLContext.sharedInstance().configureWithError(&configureError)
        if configureError != nil 
            print("Error configuring the Google context: \(configureError)")
                
        let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

        GCMService.sharedInstance().startWithConfig(GCMConfig.defaultConfig())
    

现在一切正常..
