使用UserRecordID獲取CloudKit用戶記錄

Question

問題是在獲取UserRecordID時從用戶記錄中獲取數據。

方法來獲得用戶ID： post.creatorUserRecordID .recordName

我的用戶記錄類型包含了諸如用戶名列，所以，我需要分析他們的具體用戶？以某種方式可能嗎？

如果我理解你的問題，並且你已經有一個CKRecordID。你所要做的就是使用你得到的這個CKRecordID來獲取RecordRecordWithID。

let publicDatabase = CKContainer.defaultContainer().publicCloudDatabase 
publicDatabase.fetchRecordWithID(recordId, completionHandler: { (fetchRecord: CKRecord?, fetchError: NSError?) in 
    if let error = fetchError 
    { 
     // error getting user record, try again 
     print("-> cloudKitFetchUserRecord - error fetching user record - Error \(error)") 
    } 
    else 
    { 
     if let record = fetchRecord 
     { 
      if record.recordType == CKRecordTypeUserRecord 
      { 
       // valid record 
       print("-> cloudKitFetchUserRecord - fetching user record - valid record found - \(record.recordID.recordName))") 

       // unwrap your values - on your case username 
       if let object = record.objectForKey("username") as? Bool 
       { 
        // do something with object 
       } 

      } 
      else 
      { 
       // not valid record 
       print("-> cloudKitFetchUserRecord - fetching user record - The record that came back is not a CKRecordTypeUserRecord") 
      } 
     } 
     else 
     { 
      // record nil 
      print("-> cloudKitFetchUserRecord - fetching user record - fetch record returned nil") 
     } 
    } 
})
