CloudKit：删除CKSubscription不起作用
您好，我尝试取消CloudKit上的订阅。 到目前为止，我尝试了CKModifySubscriptionsOperation和单一删除publicDB？.deleteSubscriptionWithID。 我的completionHandler给了我没有错误和一个已删除的订阅ID的数组。 所以一切似乎都没问题。
但是，当我改变一个logging，我仍然得到一个推送通知。 如何删除订阅？
这是更改的代码：
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) } 我的订阅仍然处于活动状态： CloudKit Dashboard

和删除订阅：错误=零

好吧，这不是确定的答案，但需要放下一些代码，评论太短。 这是什么意思呢; 第一种方法获取任何未完成的通知，第二种方法确保你关注他们的同一页面。
在理想情况下删除订阅之前，您需要确保您有类似的地方。
免责声明这是演示代码; 我还没有广泛的testing。 但它应该工作。
