【问题描述】：

我正在尝试使用 CloudKit 和 Swift 订阅推送通知。这是我的代码：

应用委托：

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

    //Push
    let settings = UIUserNotificationSettings(forTypes: .Alert, categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()
    if let options: NSDictionary = launchOptions 
        let remoteNotification = options.objectForKey(UIApplicationLaunchOptionsRemoteNotificationKey) as? NSDictionary
        if let notification = remoteNotification 
            self.application(application, didReceiveRemoteNotification: notification as! [NSObject : AnyObject])
        
    

    return true



func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) 
    let ckNotification = CKNotification(fromRemoteNotificationDictionary: userInfo as! [String : NSObject])
    if ckNotification.notificationType == .Query 
        let queryNotification = ckNotification as! CKQueryNotification
        let recordID = queryNotification.recordID
        let container = CKContainer.defaultContainer()
        let privateDatabase = container.privateCloudDatabase
        privateDatabase.fetchRecordWithID(recordID!) newRecord, error in
            if error != nil 
                print(error)
             else 
                NSOperationQueue.mainQueue().addOperationWithBlock( () -> Void in
                    print(newRecord)
                )
            
        
    

创作：

func addNewRecordsSub() 
    let subscription = CKSubscription(recordType: "UserRecords", predicate: predicate, options: .FiresOnRecordCreation)
    let notificationInfo = CKNotificationInfo()
    notificationInfo.alertBody = "OK!"
    notificationInfo.shouldBadge = true
    subscription.notificationInfo = notificationInfo
    let privateDatabase = container.privateCloudDatabase
    privateDatabase.saveSubscription(subscription)  subscription, error in
        if error != nil 
            print(error)
        

    

在 CloudKit 的仪表板中出现启动订阅后：

但是当我添加新记录时什么都没有发生……什么都没有。我错过了什么吗？

【问题讨论】：

你有没有尝试实现desiredKeys & soundName，看看有什么不同？ notificationInfo.desiredKeys = ["yourKey1", "yourKey2"] & notificationInfo.soundName = UILocalNotificationDefaultSoundName

@Allen 仍然不起作用。

我也尝试过重置环境，但还是没有。

您是在同一台设备上创建新记录吗？你不会收到通知。您必须在其他设备或仪表板中创建新记录

【参考方案1】：

我尝试再次重置环境，现在一切正常...
