iOS GCM通知正在发送，但未显示

我正在尝试在我的iOS应用程序中实现GCM。一切似乎都很好，该应用程序正在连接到GCM并获得注册ID。如果我用邮递员向那个regid发送通知，它就会工作，我会从谷歌那里得到一个成功的回复。然而，不管我怎么做，通知实际上并没有显示在设备上

我正在使用的GCM服务器的post消息是

{
    "to" : "RegID",
    "content_available" : true,
    "notification" : {
        "body" : "Test Body",
        "title" : "Test Title"
    }
}

我的回答是：

{
    "multicast_id": 6594175386712804014,
    "success": 1,
    "failure": 0,
    "canonical_ids": 0,
    "results": [
        {
            "message_id": "0:1443445858075083%c4cfa24dc4cfa24d"
        }
    ]
}

这让我相信我的应用程序中的代码有问题。下面我粘贴了所有相关的代码。我已经编写了3次代码，但都没有成功，第一次是遵循教程并将其正确地编辑到我的应用程序中，第二次是从教程中复制代码，第三次是从Github repo获得示例应用程序，并复制了与GCM相关的所有内容

AppDelegate：

class AppDelegate: UIResponder, UIApplicationDelegate  {

    var window: UIWindow?

    var connectedToGCM = false
    var gcmSenderID: String?
    var registrationToken: String?
    var registrationOptions = [String: AnyObject]()
    let defaults = NSUserDefaults.standardUserDefaults()

    let registrationKey = "onRegistrationCompleted"
    let messageKey = "onMessageReceived"
    let notification = "isNotificationEnabled"

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Google Cloud Messaging
        var configureError:NSError?
        GGLContext.sharedInstance().configureWithError(&configureError)
        assert(configureError == nil, "Error configuring Google services: \(configureError)")
        gcmSenderID = GGLContext.sharedInstance().configuration.gcmSenderID

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

        var gcmConfig = GCMConfig.defaultConfig()
        GCMService.sharedInstance().startWithConfig(gcmConfig)

        return true
    }

    func applicationDidBecomeActive(application: UIApplication) {              
        GCMService.sharedInstance().connectWithHandler({
            (NSError error) -> Void in
            if error != nil {
                println("Could not connect to GCM: \(error.localizedDescription)")
            } else {
                self.connectedToGCM = true
                println("Connected to GCM")
                // ...
            }
        })

    }

    func application( application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken
        deviceToken: NSData ) {
            println(deviceToken)
            // [END receice_apns_token]
            // [START get_gcm_reg_token]
            // Create a config and set a delegate that implements the GGLInstaceIDDelegate protocol.
            var instanceIDConfig = GGLInstanceIDConfig.defaultConfig()
            // Start the GGLInstanceID shared instance with that config and request a registration
            // token to enable reception of notifications
            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 registrationHandler(registrationToken: String!, error: NSError!) {
        if (registrationToken != nil) {
            self.registrationToken = registrationToken
            println("Registration Token: \(registrationToken)")
            let userInfo = ["registrationToken": registrationToken]
            NSNotificationCenter.defaultCenter().postNotificationName(
                self.registrationKey, object: nil, userInfo: userInfo)
        } else {
            println("Registration to GCM failed with error: \(error.localizedDescription)")
            let userInfo = ["error": error.localizedDescription]
            NSNotificationCenter.defaultCenter().postNotificationName(
                self.registrationKey, object: nil, userInfo: userInfo)
        }
    }

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


    func application( application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        println("Notification received: \(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]
        NSNotificationCenter.defaultCenter().postNotificationName(messageKey, object: nil,
            userInfo: userInfo)
    }

如果之前有人问过类似的问题，请告诉我，我找不到一个能正确描述我处境的问题

提前谢谢

您尚未实现适当的通知回调。你需要实施

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

   // Do something with userInfo
   // call fetchCompletionHandler with the appropriate UIBackgroundFetchResult 
}

静默推送通知（即设置了

内容可用
标志的通知）调用上述
uiapplicationelegate
方法，而不是
application:didReceiveMotonification:

另外，请确保已将
远程通知
值添加到
Info.plist
中的
ui背景模式
 您的HTTP请求看起来不错。但是在您的实现和应用程序之间存在一些差异。您应该尝试复制并粘贴该示例项目中的所有行，或者下载该示例项目。您的链接中有哪些内容负责显示通知？看起来主要是UI代码。从谷歌教程中我了解到，他们Appdelegate中的代码应该足以显示一个简单的通知？我从没想过苹果会允许你在IOS上使用任何非APNS的推送通知。@Dan在示例项目中。你是上帝，这解决了我的问题。是否有任何方法可以使用fetchCompletionHandler更新UITableView？在调用
fetchCompletionHandler
之前，您可以执行任何更新。处理程序只是用来通知iOS您已经完成了您想要执行的任何更新。
