SWIFT：我没有从CloudKit应用程序收到通知？

这是我的代码：

@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 } 

这是一个消息传递应用程序，所以人们可以互相发送消息，但我也希望他们收到通知。 这是通知代码，我还在App Delegate中有一些通知代码：

 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，即使我拥有在每次有人发送消息时发出通知所需的所有代码，通知也不会进入。 我错过了什么吗？ 谢谢！

有人回答我之前说：

您正在向公共数据库添加数据，但您正在私有数据库上创建订阅。 其中一个需要更改以匹配另一个。

所以我改变了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，要发送通知，您注册用户推送通知。 对于案例如果注册成功，则必须实现上述方法。 如果注册失败，你必须实现这个：

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