【问题描述】：

在 ios 中使用 GCM 进行推送通知。一切都设置得很好。我获得了registrationToken 值并且也成功地subscribeToTopic。连接到 GCM。 didRegisterForRemoteNotificationsWithDeviceToken 方法也被调用。但没有收到推送通知。 didReceiveRemoteNotification 方法从未调用过。在我的 android 应用程序上，我收到推送通知没有任何问题。但在 iOS 中从未收到通知。以下是源代码：

    class AppDelegate: UIResponder, UIApplicationDelegate, GGLInstanceIDDelegate, GCMReceiverDelegate
var gcmSenderID: String?
var registrationToken: String?
let registrationKey = "onRegistrationCompleted"
let messageKey = "onMessageReceived"
var registrationOptions = [String: AnyObject]()
var connectedToGCM = false
let subscriptionTopic = "/topics/global"
var subscribedToTopic = false

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

    var configureError:NSError?

    GGLContext.sharedInstance().configureWithError(&configureError)

    gcmSenderID = GGLContext.sharedInstance().configuration.gcmSenderID

    if application.respondsToSelector("registerUserNotificationSettings:") 

        let types:UIUserNotificationType = (.Alert | .Badge | .Sound)
        let settings:UIUserNotificationSettings = UIUserNotificationSettings(forTypes: types, categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()

     else 
        // Register for Push Notifications before iOS 8
        application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
    
    let gcmConfig = GCMConfig.defaultConfig()
    gcmConfig.receiverDelegate = self
    GCMService.sharedInstance().startWithConfig(gcmConfig)

    return true



func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
    print("remote notification")
    GCMService.sharedInstance().appDidReceiveMessage(userInfo);


func application( application: UIApplication,
    didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
    fetchCompletionHandler handler: (UIBackgroundFetchResult) -> Void) 
        GCMService.sharedInstance().appDidReceiveMessage(userInfo);

   NSNotificationCenter.defaultCenter().postNotificationName(messageKey, object: nil,
            userInfo: userInfo)
        handler(UIBackgroundFetchResult.NoData);



func application( application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken
    deviceToken: NSData ) 

        let instanceIDConfig = GGLInstanceIDConfig.defaultConfig()
        instanceIDConfig.delegate = self

     GGLInstanceID.sharedInstance().startWithConfig(instanceIDConfig)
        registrationOptions = [kGGLInstanceIDRegisterAPNSOption:deviceToken,
            kGGLInstanceIDAPNSServerTypeSandboxOption:true]

        GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(gcmSenderID,
            scope: kGGLInstanceIDScopeGCM, options: registrationOptions, handler: registrationHandler)
        // [END get_gcm_reg_token]

func onTokenRefresh() 
    // A rotation of the registration tokens is happening, so the app needs to request a new token.
    print("The GCM registration token needs to be changed.")
    GGLInstanceID.sharedInstance().tokenWithAuthorizedEntity(gcmSenderID,
        scope: kGGLInstanceIDScopeGCM, options: registrationOptions, handler: registrationHandler)

func registrationHandler(registrationToken: String!, error: NSError!) 
    if (registrationToken != nil) 

        self.registrationToken = registrationToken
        print("Registration Token: \(registrationToken)")
        self.subscribeToTopic()
        let userInfo = ["registrationToken": registrationToken]
        NSNotificationCenter.defaultCenter().postNotificationName(
            self.registrationKey, object: nil, userInfo: userInfo)
     else 
        print("Registration to GCM failed with error: \(error.localizedDescription)")
        let userInfo = ["error": error.localizedDescription]
        NSNotificationCenter.defaultCenter().postNotificationName(
            self.registrationKey, object: nil, userInfo: userInfo)
    

func subscribeToTopic() 

    // topic
    if(registrationToken != nil && connectedToGCM) 
        GCMPubSub.sharedInstance().subscribeWithToken(self.registrationToken, topic: subscriptionTopic,
            options: nil, handler: (NSError error) -> Void in
                if (error != nil) 
                    // Treat the "already subscribed" error more gently
                    if error.code == 3001 
                        print("Already subscribed to \(self.subscriptionTopic)")
                     else 
                        print("Subscription failed: \(error.localizedDescription)");
                    
                 else 
                    self.subscribedToTopic = true;
                    NSLog("Subscribed to \(self.subscriptionTopic)");
                
        )
    



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

         else 
            self.connectedToGCM = true
            self.subscribeToTopic()
            print("Connected to GCM")
            // ...
        
    )

我做错了什么。有人可以推荐吗？

【问题讨论】：

您是否在应用目标中设置了正确的功能？并制定了推送规定？

是的，我有推送条款。我需要在应用目标中添加任何其他内容吗？？

您需要在功能部分打开它，并且在构建应用程序时，您需要在您的机器上拥有推送通知密钥/证书对，以便您构建它

可能重复的 SO 票请参考此link

对于您的链接无法解决我的问题的信息

【参考方案1】：

您应该可以选择从功能部分打开推送。您还需要在苹果会员中心建立单独的密钥/证书对，并将它们包含在您的机器上。这是我做的一个新项目的截图。

听起来可能流程中的某个步骤可能没有完成。

重新开始，试着找出你错过了什么。这是一个 ray wenderlich 教程，将引导您完成步骤here

以及深入讨论它的 Apple 开发者网站的链接here

【讨论】：

我正在使用 xcode 6。从 link 我可以看到 push 不再是 xcode 6 中的选项。而是应该通过代码激活

好的。现在我要删除我所有的证书和配置文件。然后重新创建它们。我在这里有个问题。我已经将应用程序提交到应用商店。重新创建证书会影响 appstore 应用吗？？

是的，非常小心，你应该使用一个有用的工具，叫做 Pusher，它会在你删除所有内容并统计数据之前告诉你出了什么问题
