SWIFT：我沒有從CloudKit應用程序收到通知？

Question

這是我的代碼：

    @IBAction func sendSweet(sender: AnyObject) {

    //delegate method

    let newSweet = CKRecord(recordType: "Extra1")
    newSweet["content"] = textField.text

    let publicData = CKContainer.defaultContainer().publicCloudDatabase
    publicData.saveRecord(newSweet, completionHandler: { (record:CKRecord?, error:NSError?) -> Void in
        if error == nil {
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                self.tableView.beginUpdates()
                self.sweets.insert(newSweet, atIndex: 0)
                let indexPath = NSIndexPath(forRow: 0, inSection: 0)
                self.tableView.insertRowsAtIndexPaths([indexPath], withRowAnimation: .Top)
                self.tableView.endUpdates()
                self.textField.text = ""
                self.textField.resignFirstResponder()



            })


        }})
    // Put the CloudKit private database in a constants
    let privateDatabase = CKContainer.defaultContainer().publicCloudDatabase

    // Create subscription and set three of its properties (an id, a predicate, and options)
    let friendsSubscription = CKSubscription(recordType: "Extra1",
        predicate: NSPredicate(format: "TRUEPREDICATE"),
        subscriptionID: "Extra1",
        options: .FiresOnRecordCreation)

    // Create a notification and set two of its properties (alertBody and shouldBadge)
    let notificationInfo = CKNotificationInfo()
    notificationInfo.alertBody = "New message in Lms Chat"
    notificationInfo.shouldBadge = false

    // Attach the notification to the subscription
    friendsSubscription.notificationInfo = notificationInfo

    // Save the subscription in the private database
    privateDatabase.saveSubscription(friendsSubscription) {recordReturned, error in
        // On the main thread, display an error/success message in the textView
        if error != nil {
            NSOperationQueue.mainQueue().addOperationWithBlock {
                self.textField.text = "Cloud error\n\(error!.localizedDescription)"
            }
        } else {
            NSOperationQueue.mainQueue().addOperationWithBlock {
                self.textField.text = ""
            }
        }
    }

}
func textFieldShouldEndEditing(textField: UITextField!) -> Bool {  //delegate method
    return false
}

func textFieldShouldReturn(textField: UITextField!) -> Bool {   //delegate method
    textField.resignFirstResponder()

    return true

}

這是一個消息傳遞應用程序，所以人們可以互相發信息，但我也希望他們收到通知。 這是通知代碼，我還在App Delegate中有一些通知代碼：

import UIKit
    import CloudKit

    @UIApplicationMain
    class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?


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

    let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)

    UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)

    UIApplication.sharedApplication().registerForRemoteNotifications()

    return true
}


func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    let cloudKitNotification = CKNotification(fromRemoteNotificationDictionary: userInfo as! [String:NSObject])

    if cloudKitNotification.notificationType == CKNotificationType.Query {
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            NSNotificationCenter.defaultCenter().postNotificationName("performReload", object: nil)
        })

    }

}

func resetBadge () {
    let badgeReset = CKModifyBadgeOperation(badgeValue: 0)
    badgeReset.modifyBadgeCompletionBlock = { (error) -> Void in
        if error == nil {
            UIApplication.sharedApplication().applicationIconBadgeNumber = 0
        }

    }

    CKContainer.defaultContainer().addOperation(badgeReset)
}


func applicationWillResignActive(application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

func applicationDidEnterBackground(application: UIApplication) {
    resetBadge()

}

func applicationWillEnterForeground(application: UIApplication) {
    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        NSNotificationCenter.defaultCenter().postNotificationName("performReload", object: nil)
    })
}

func applicationDidBecomeActive(application: UIApplication) {
    resetBadge()
}

func applicationWillTerminate(application: UIApplication) {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

}

但是，即使每次有人發送消息時我都擁有發送通知所需的所有代碼，但通知也不會進入。 我錯過了什么嗎？ 謝謝！

有人回答我之前說：

您正在向公共數據庫添加數據，但您正在私有數據庫上創建訂閱。 其中一個需要更改以匹配另一個。

所以我改變了let privateDatabase = CKContainer.defaultContainer().privateCloudDatabase let privateDatabase = CKContainer.defaultContainer().publicCloudDatabase

在您的app Delegate中，您缺少此方法：

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

    print(deviceToken)       // This is the device token
    var token: String = "\(deviceToken)"    /// formatted token.

    let rawtoken = token.stringByReplacingOccurrencesOfString(">", withString: "")
    let cleantoken = rawtoken.stringByReplacingOccurrencesOfString("<", withString: "")
    var finaltoken = cleantoken.stringByReplacingOccurrencesOfString(" ", withString: "")
    // Send device token to server

            }
        }
    }

我的意思是，要發送通知，您注冊用戶推送通知。 對於案例如果注冊成功，則必須實現上述方法。 如果注冊失敗，你必須實現這個：

 func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    print(error)

}
