CloudKit CKShare用户DidAcceptCloudKitShareWith从不在Mac App上触发 [英] CloudKit CKShare userDidAcceptCloudKitShareWith Never Fires on Mac App

问题描述

我正在努力在Swift 4的macOS应用中接受 CKShare 。我已经完成以下所有操作：

• 创建 CKShare 并将其 rootRecord 保存到CloudKit


• 添加参与者（ CKShare.Participant ）


• 我已确认 CKShare 在CloudKit服务器上，我邀请的人可以访问它。这是屏幕截图：
  
  
  

  单击确定使屏幕淡出：

  
  
  
  
  
  

  不是特别有用。 :)执行此操作后，参与者在CloudKit中的状态仍然为已邀请，因此仍未接受该共享。

  
  
  

  当我单击在消息中的共享链接上，显示了这样的弹出窗口：
  
  单击打开后，该应用程序的新副本将显示在扩展坞中，然后该应用突然关闭。崩溃日志指出：

  
  

  由于未捕获的异常 CKException而终止应用程序，原因：应用程序缺少必需的权限com.apple。 developer.icloud-services'

  
  

  我尝试在Xcode的功能部分中关闭iCloud，然后再打开，但没有任何改变。我知道这种例外情况是不对的，因为我可以正常启动我的应用并全天使用CloudKit。只有 CKShare 会导致此崩溃。

  
  
  

  这真是一团糟。救救我，欧比万·基诺比，你是我唯一的希望。

  解决方案

  是，

  
  
  

  您需要将此添加到您的info.plist。

   < key> CKSharingSupported< / key> ; 
  < true />

  我使用此代码共享，我不手动执行...不确定在OS XI下必须承认这是否是一个选项。我正在使用iOS。

    let share = CKShare（rootRecord：record2S！）
   share [CKShareTitleKey] =我的下一个共享作为CKRecordValue 
   share.publicPermission = .none 
   
  让SharingController = UICloudSharingController（preparationHandler：{（UICloudSharingController，handler：
   @escaping（CKShare ?, CKContainer ?, Error ？）->无效）在
  中让ModifyOp = CKModifyRecordsOperation（recordsToSave：
   [record2S !, share]，recordIDsToDelete：nil）
   ModifyOp.savePolicy = .allKeys 
   ModifyOp。 ModifyRecordsCompletionBlock = {（记录，记录ID，
  错误）在
  处理程序中（share，CKContainer.default（），错误）
  } 
   CKContainer.default（）。privateCloudDatabase.add（ ModifyOp）
  }）
   SharingController.availablePermissions = [.allowReadWrite，
   .allowP rivate] 
   SharingController.delegate =自我
   SharingController.popoverPresentationController？.sourceView = self.view 
   DispatchQueue.main.async {
   self.present（sharingController，animation：true，完成：nil）
  } 
    

  这提供了一个活动控制器，您可以在其中选择说出电子邮件并然后发送链接。您可能还想观看此视频，一开始就专注于cloudKit JS。

  
  
  

  也请观看此WWDC视频 https://developer.apple.com/videos/play/wwdc2015/710/
  它谈论了Cloudkit JSON API，使用它可以查询终端窗口/简单脚本中共享的内容。几年前使用Dropbox API时，我做了相同的事情。嘿，您甚至可以在代码中使用cloudkit JSON API代替本地调用。

  
  

  I am working on accepting a CKShare in a macOS app in Swift 4. I've already done all the following:

  • Create the CKShare and save it with its rootRecord to CloudKit
  • Add a participant (CKShare.Participant)
  • I've confirmed that the CKShare is on the CloudKit server and that the person I invited has access to it. Here's a screenshot: https://d.pr/i/0sMFQq

  When I click the share link associated with the CKShare, it opens my app, but nothing happens and userDidAcceptCloudKitShareWith doesn't fire.

  func application(_ application: NSApplication, userDidAcceptCloudKitShareWith metadata: CKShareMetadata) {
    print("Made it!") //<-- This never gets logged :(
    let shareOperation = CKAcceptSharesOperation(shareMetadatas: [metadata])
    shareOperation.qualityOfService = .userInteractive
  
    shareOperation.perShareCompletionBlock = {meta, share, error in
      print("meta \(meta)\nshare \(share)\nerror \(error)")
    }
    shareOperation.acceptSharesCompletionBlock = { error in
      if let error = error{
        print("error in accept share completion \(error)")
      }else{
        //Send your user to where they need to go in your app
        print("successful share:\n\(metadata)")
      }
    }
  
    CKContainer.default().add(shareOperation)
  }
  

  Is there some kind of URL scheme I have to include in my info.plist? Or perhaps a protocol I need to conform to in my NSApplicationDelegate delegate? I can't, for the life of me, figure out what to do. Thanks in advance!

  Update

  I've tried a few more things on this. When I open the share link in a web browser, I see this:

  Clicking OK makes the screen fade away to this:

  Not particularly helpful. :) After doing this, the participant's status in CloudKit is still Invited, so the share still hasn't been accepted.

  When I click on a share link within Messages, I am shown a popup like this: After I click open, a new copy of my app shows up in the dock, then the app suddenly closes. The crash log states:

  Terminating app due to uncaught exception 'CKException', reason: 'The application is missing required entitlement com.apple.developer.icloud-services'

  I've tried turning iCloud off and on again in the Capabilities section of Xcode, but nothing changes. I know this exception can't be right because I can start my app normally and use CloudKit all day long. Only the CKShare causes this crash.

  This is a mess. Save me, Obi-wan Kenobi, you're my only hope.

  解决方案

  Yes,

  You need to add this to your info.plist.

  <key>CKSharingSupported</key>
  <true/>
  

  ** EDITED ANSWER **

  I use this code to share, I don't do it manually... not sure if this is an option under OS X I must confess. I am using iOS.

  let share = CKShare(rootRecord: record2S!)
  share[CKShareTitleKey] = "My Next Share" as CKRecordValue
  share.publicPermission = .none
  
  let sharingController = UICloudSharingController(preparationHandler: {(UICloudSharingController, handler:
                      @escaping (CKShare?, CKContainer?, Error?) -> Void) in
  let modifyOp = CKModifyRecordsOperation(recordsToSave:
                          [record2S!, share], recordIDsToDelete: nil)
  modifyOp.savePolicy = .allKeys
  modifyOp.modifyRecordsCompletionBlock = { (record, recordID,
                          error) in
                          handler(share, CKContainer.default(), error)
                      }
                      CKContainer.default().privateCloudDatabase.add(modifyOp)
                  })
  sharingController.availablePermissions = [.allowReadWrite,
                                                            .allowPrivate]
  sharingController.delegate = self
                  sharingController.popoverPresentationController?.sourceView = self.view
              DispatchQueue.main.async {
                  self.present(sharingController, animated:true, completion:nil)
              }
  

  This presents an activity controller in which you can choose say email and then send a link. You might also want to watch this video, focus on cloudKit JS right at the beginning.

  Watch this WWDC video too https://developer.apple.com/videos/play/wwdc2015/710/ It talks about the cloudkit JSON API, using it you can query what has and what hasn't been shared in a terminal window/simple script perhaps. I did the same when using dropbox API a few years back. Hey you can even use the cloudkit JSON API within your code in place of the native calls.
