【问题描述】：

我正在尝试在 Xcode 7.0 GM 中使用 Swift 2 解析推送通知。问题是它连接但没有显示推送..你知道为什么吗？提前谢谢你

这是我的代码.. 当然我删除了我的 Parse ID 但在我的项目中有..我尝试使用 Parse 提供的代码但我遇到了错误.. 所以我在 Github 上使用了一个项目但它不是工作..

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

    Parse.setApplicationId("here there is my ID of course")

    PFUser.enableAutomaticUser()

    let defaultACL = PFACL();

    // If you would like all objects to be private by default, remove this line.
    defaultACL.setPublicReadAccess(true)

    PFACL.setDefaultACL(defaultACL, withAccessForCurrentUser:true)

    if application.applicationState != UIApplicationState.Background 
        // Track an app open here if we launch with a push, unless
        // "content_available" was used to trigger a background push (introduced in ios 7).
        // In that case, we skip tracking here to avoid double counting the app-open.

        let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
        let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
        var noPushPayload = false;
        if let options = launchOptions 
            noPushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil;
        
        if (preBackgroundPush || oldPushHandlerOnly || noPushPayload) 
            PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
        
    

    if application.respondsToSelector("registerUserNotificationSettings:") 
        let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)



        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
     else 
        let types: UIRemoteNotificationType = [UIRemoteNotificationType.Badge, UIRemoteNotificationType.Alert, UIRemoteNotificationType.Sound]
        application.registerForRemoteNotificationTypes(types)
    


    return true







//--------------------------------------
// MARK: Push Notifications
//--------------------------------------

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

    PFPush.subscribeToChannelInBackground("")  (succeeded, error) in
        if succeeded 
            print("ParseStarterProject successfully subscribed to push notifications on the broadcast channel.");
         else 
            print("ParseStarterProject failed to subscribe to push notifications on the broadcast channel with error = %@.", error)
        
    


func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) 
    if error.code == 3010 
        print("Push notifications are not supported in the iOS Simulator.")
     else 
        print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
    


func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
    PFPush.handlePush(userInfo)
    if application.applicationState == UIApplicationState.Inactive 
        PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
    

【问题讨论】：

“它连接”是什么意思？您是否设置了推送证书（调试和推送）并将其上传到 Parse？

是的，我想是的.. 我的意思是它打印这个 print("ParseStarterProject 成功订阅了广播频道上的推送通知。");

在解析时是否显示它发送了推送/是否收到？

现在我什么也没看到：\

【参考方案1】：

我遇到了同样的问题，可能是由以下原因之一引起的：

1) 确保您在真实设备上运行它，而不是模拟器。模拟器不支持推送通知。

2) 在您的设备上重新安装您的应用。这解决了我的问题。当它询问时，显然允许它发送推送通知。

2) 重新创建您的证书和配置文件。单击here 了解如何操作。

3) 确保您的证书有效且已安装。双击下载的配置文件进行安装。

您可能还想创建一个用户并尝试使用它，而不是自动用户。

编辑： 我建议您按照here 的快速入门。我知道你会得到错误，所以这里是如何解决它们：

1) 删除let userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound 并删除let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)。然后在删除行的位置输入let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)。

2) 将let types = UIRemoteNotificationType.Badge | UIRemoteNotificationType.Alert | UIRemoteNotificationType.Sound 行替换为let types = UIRemoteNotificationType.Badge.union(UIRemoteNotificationType.Alert).union(UIRem‌​oteNotificationType.Sound)

【讨论】：

做了所有这些但没有工作..你知道 swift 2 的代码吗？

问题只是它没有显示推送..我认为它连接得很好

创建用户是什么意思？

【参考方案2】：

我有同样的问题。我用谷歌搜索并进行了实验，然后它开始完美运行。我认为代码更改没有任何区别。可以解析有问题吗？以下是我的代码（来自谷歌搜索），并且推送通知工作：

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

        Parse.setApplicationId("***your id ***",
            clientKey: "*** your key ***")

        // Register for Push Notitications
        if application.applicationState != UIApplicationState.Background 
            // Track an app open here if we launch with a push, unless
            // "content_available" was used to trigger a background push (introduced in iOS 7).
            // In that case, we skip tracking here to avoid double counting the app-open.

            let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
            let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
            var pushPayload = false
            if let options = launchOptions 
                pushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil
            
            if (preBackgroundPush || oldPushHandlerOnly || pushPayload) 
                PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
            
        

        /*
        if application.respondsToSelector("registerUserNotificationSettings:") 
            let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
            application.registerUserNotificationSettings(settings)
            application.registerForRemoteNotifications()
         else 
            let types : UIRemoteNotificationType = [.Badge, .Alert, .Sound]
            application.registerForRemoteNotificationTypes(types)

        
        */

        let settings = UIUserNotificationSettings(forTypes: [.Alert, .Sound, .Badge], categories: nil)
        UIApplication.sharedApplication().registerUserNotificationSettings(settings)
        UIApplication.sharedApplication().registerForRemoteNotifications()

        // check if app opened because user tapped on notification
        if let launchOptions = launchOptions as? [String : AnyObject] 
            if let notificationDictionary = launchOptions[UIApplicationLaunchOptionsRemoteNotificationKey] as? [NSObject : AnyObject] 
                self.application(application, didReceiveRemoteNotification: notificationDictionary)
            
        



        return true
    


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


    /*
    func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) 
        let installation = PFInstallation.currentInstallation()
        installation["user"] = PFUser.currentUser()
        installation.setDeviceTokenFromData(deviceToken)
        installation.saveInBackground()
    
    */

    func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) 
        if error.code == 3010 
            print("Push notifications are not supported in the iOS Simulator.")
         else 
            print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
        
    


    func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
        PFPush.handlePush(userInfo)
        if application.applicationState == UIApplicationState.Inactive 
            PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
