CloudKit：删除CKSubscription不起作用

Question

您好，我尝试取消CloudKit上的订阅。 到目前为止，我已经通过publicDB？.deleteSubscriptionWithID尝试了CKModifySubscriptionsOperation和single removement。我的completionHandler给了我没有错误和一个已删除订阅ID的数组。所以一切似乎都没问题。

但是，当我改变记录我仍然得到推送通知。 如何删除订阅？

这里是改变的代码：订阅时 CloudKit Dashboard

我的日志：

func cancelCubscription(subscription:Subscriptions){ 
    self._animationDelegate?.beginAnimation() 
    var subs = [String]() 
    subs.append(subscription.daySubSignature!) 
    subs.append(subscription.hdpSubSignature!) 
    subs.append(subscription.noteSubSignature!) 
    subs.append(subscription.planerSubSignature!) 
    subs.append(subscription.subjectSubSugnature!) 
    subs.append(subscription.teacherSubSignature!) 
    subs.append(subscription.tldSubSignature!) 

    // Create a CKModifyRecordsOperation operation 
    let subscriptionOperation = CKModifySubscriptionsOperation(subscriptionsToSave: nil, subscriptionIDsToDelete: subs) 

    subscriptionOperation.modifySubscriptionsCompletionBlock = { (modifiedSubscriptions: [CKSubscription]?, deletedSubscriptionIDs: [String]?, error: NSError?) -> Void in 
     guard error==nil else { 
      dispatch_async(dispatch_get_main_queue(), {() -> Void in 
       self._animationDelegate?.endAnimation() 
       print(error!.localizedDescription) 

       let title:String = "Alert_Cancel_CloudKit_Subscription_Error_Title".localized 
       let message:String = error!.localizedDescription 

       self._alertDelegate?.showAlert(title, message: message) 
      }) 
      return 
     } 

     dispatch_async(dispatch_get_main_queue(), {() -> Void in 
      self._animationDelegate?.endAnimation() 
      print("") 
      print("- * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - * - *") 
      print("Unscribe to CloudKit subscription success!") 

      let title:String = "Alert_Cancel_CloudKit_Subscription_Success_Title".localized 
      let message:String = "Alert_Cancel_CloudKit_Subscription_Success_Message".localized 

      self._alertDelegate?.showAlert(title, message: message) 

      for sub in deletedSubscriptionIDs!{ 
       print("Deleted Subscription: \(sub)") 
      } 

      subscription.tldSubSignature = "null" 
      subscription.daySubSignature = "null" 
      subscription.hdpSubSignature = "null" 
      subscription.noteSubSignature = "null" 
      subscription.planerSubSignature = "null" 
      subscription.subjectSubSugnature = "null" 
      subscription.teacherSubSignature = "null" 
      subscription.subscribed = false 
      Subscriptions.editSubsripction(subscription, context: self.appDel.managedObjectContext) 
     }) 
    } 

    // Add the operation to an operation queue to execute it 
    self._publicDB!.addOperation(subscriptionOperation) 
} 

我的租约仍然有效

好吧，这不是确定的答案，但需要放下一些代码，并且评论太短。这是什么意思呢;第一种方法可以获取任何未完成的通知，第二种方法可以确保您的页面与他们的注意力相同。

在理想情况下删除订阅之前，您需要确保您有类似的地方。

声明这是演示代码;我还没有广泛的测试它。但它应该工作。

func fetchSubsInPlace() { 
    let container = CKContainer(identifier: "iCloud.ch") 
    let publicDB = container.publicCloudDatabase 

    publicDB.fetchAllSubscriptionsWithCompletionHandler({subscriptions, error in 
     for subscriptionObject in subscriptions! { 
      let subscription: CKSubscription = subscriptionObject as CKSubscription 
      print("subscription \(subscription)") 
     } 
    }) 
} 

func fetchNotificationChanges() { 
    let operation = CKFetchNotificationChangesOperation(previousServerChangeToken: nil) 

    var notificationIDsToMarkRead = [CKNotificationID]() 

    operation.notificationChangedBlock = { (notification: CKNotification) -> Void in 
     // Process each notification received 
     if notification.notificationType == .Query { 
      let queryNotification = notification as! CKQueryNotification 
      let reason = queryNotification.queryNotificationReason 
      let recordID = queryNotification.recordID 

      print("reason \(reason)") 
      print("recordID \(recordID)") 
      // Do your process here depending on the reason of the change 

      // Add the notification id to the array of processed notifications to mark them as read 
      notificationIDsToMarkRead.append(queryNotification.notificationID!) 
     } 
    } 

    operation.fetchNotificationChangesCompletionBlock = { (serverChangeToken: CKServerChangeToken?, operationError: NSError?) -> Void in 
     guard operationError == nil else { 
      // Handle the error here 
      return 
     } 

     // Mark the notifications as read to avoid processing them again 
     let markOperation = CKMarkNotificationsReadOperation(notificationIDsToMarkRead: notificationIDsToMarkRead) 
     markOperation.markNotificationsReadCompletionBlock = { (notificationIDsMarkedRead: [CKNotificationID]?, operationError: NSError?) -> Void in 
      guard operationError == nil else { 
       // Handle the error here 
       return 
      } 
     } 

     let operationQueue = NSOperationQueue() 
     operationQueue.addOperation(markOperation) 
    } 

    let operationQueue = NSOperationQueue() 
    operationQueue.addOperation(operation) 
} 


}
