【问题描述】：

我正在尝试为记录分配几个不同的属性。

日期和名称工作正常。 Avatar 是对另一条记录的引用，也可以正常工作。但后来我尝试为用户分配一个引用，我得到了对屏幕的猛烈抨击。这是我的代码：

var avatarID : CKRecordID!
var userID : CKRecordID!

//avatarID has been assigned value in another function
daMainUser.setObject(CKReference(recordID: avatarID! as CKRecordID, action: CKReferenceAction.None), forKey: "avatar")
println("this is avatarID: \(avatarID!)")

containerY.fetchUserRecordIDWithCompletionHandler
            userRecordID, error in
            if error != nil 
                println("error")
             else 
                println("gettin close")
                self.userID = userRecordID
                println("this is userID: \(self.userID!)")
                daMainUser.setObject(CKReference(recordID: self.userID! as CKRecordID, action: CKReferenceAction.None), forKey: "ownerOfThat")
                
            
        publicDatabase.saveRecord(daMainUser) 
            record, error in
            if error != nil 
                println(error.localizedDescription)
             else 
                println(record.objectForKey("nickName") as String + " recorded")
            
        

当我保存 daMainUser 并查看苹果仪表板时，我看到“头像”引用已成功保存，但没有“ownerOfThat”。这是我从控制台得到的：

this is avatarID: <CKRecordID: 0x7a83d3d0; 79CE1EDC-593D-4AE0-8433-8488F857A302:(_defaultZone:__defaultOwner__)>
gettin close
this is userID: <CKRecordID: 0x7a863910; _8a15e8e6138ba234b62f25cfd3eeb66e:(_defaultZone:__defaultOwner__)>
John Doe recorded

这让我相信 userID 和来自另一条记录的 ID 不是同一种 ID。但我不知道为什么以及该怎么做。 提前谢谢你

【参考方案1】：

我认为你的括号错了。应该是：

var avatarID : CKRecordID!
var userID : CKRecordID!

//avatarID has been assigned value in another function
daMainUser.setObject(CKReference(recordID: avatarID! as CKRecordID, action: CKReferenceAction.None), forKey: "avatar")
println("this is avatarID: \(avatarID!)")

containerY.fetchUserRecordIDWithCompletionHandler
            userRecordID, error in
            if error != nil 
                println("error")
             else 
                println("gettin close")
                self.userID = userRecordID
                println("this is userID: \(self.userID!)")
                daMainUser.setObject(CKReference(recordID: self.userID! as CKRecordID, action: CKReferenceAction.None), forKey: "ownerOfThat")
            
        publicDatabase.saveRecord(daMainUser) 
            record, error in
            if error != nil 
                println(error.localizedDescription)
             else 
                println(record.objectForKey("nickName") as String + " recorded")
            
        
     

现在您在获取记录之前保存它。

谢谢 Edwin，你又为我保存了一次屏幕。
