Question

因此，这是我的代码，允许警报和警报内写入的文本保存在云端。我实际上是在关注教程https://www.youtube.com/watch?v=XQ3nLV2778U 我在我的一些代码上收到2条错误消息！

错误：任何对象与CKRecords（位于self.post = post）
错误：CKRecords没有名为subscript的成员（位于newPost [＆＃34; content＆＃34;]

我编写的代码与教程在教程中完成的方式完全相同，只是我有错误消息而且他没有！我该如何解决这些问题？

    var posts = [CKRecord]()



override func viewDidLoad() {
    super.viewDidLoad()


}

func loadData() {
    posts = [CKRecord]()

    let publicData = CKContainer.defaultContainer().publicCloudDatabase
    let query = CKQuery(recordType: "Post", predicate: NSPredicate(format: "TRUEPREDICATE", argumentArray: nil))
    publicData.performQuery(query, inZoneWithID: nil) { (CKRecord, NSError) -> Void in
        if let posts = CKRecord{
            self.posts = posts //Error "Any Object is not Identical to CKRecords"
            dispatch_async(dispatch_get_main_queue(), { () -> Void in
                self.tableView.reloadData()
            })
        }

    }
}

@IBAction func createPost(sender: AnyObject) {

    let alert = UIAlertController(title: "New Post", message: "Enter New Post", preferredStyle: .Alert)
    alert.addTextFieldWithConfigurationHandler { (textField:UITextField!) -> Void in
        textField.placeholder = "Your Post"
    }
    alert.addAction(UIAlertAction(title: "Post", style: UIAlertActionStyle.Default, handler: { (action: UIAlertAction!) -> Void in
        let textField: AnyObject = alert.textFields!.first!

        if textField.textLabel??.text != "" {
            let newPost = CKRecord(recordType: "Post")
            newPost["content"] = textField.textLabel??.text //ERROR "CKRecord does not have a member named subscript"



            let publicData = CKContainer.defaultContainer().publicCloudDatabase
            publicData.saveRecord(newPost, completionHandler: { (record: CKRecord?, error: NSError?) -> Void in
                if error == nil {
                    print("Post Saved")
                }
            })

        }






    }))

    alert.addAction(UIAlertAction(title: "Cancel", style: .Cancel, handler: nil))
    self.presentViewController(alert, animated: true, completion: nil)

将您的Xcode更新到最新版本。

此语法从特定版本的Swift开始提供。我不记得你需要哪个版本，但如果你只是更新Xcode，你的问题就会消失。
