Swift 2.2,RealmSwift - 无法将'Note'类型的值转换为期望的参数类型Object.Type(Swift 2.2, RealmSwift - Cannot convert value of type 'Note' to expected argument type Object.Type)

我刚开始使用Realm作为记事本应用程序并保存了自定义类的数组(noteTitles)(注意)。 我把它作为一个对象,但是当我使用realm.objectForPrimaryKey(noteTitles, key: "id")它给了我一个错误:无法将'Note'类型的值转换为期望的参数类型Object.Type。 在注释的类文件中,我将其作为对象。

这是我的ViewController代码:

var note: Note!
let realm = try! Realm()

@IBOutlet var noteText: UITextView!
@IBOutlet var noteTitle: UITextField!

func textViewDidEndEditing(textView: UITextView) {


    try! realm.write{

       realm.add(noteTitles)



    }

    print("editing ended")

}


override func viewDidLoad() {
    super.viewDidLoad()


    self.noteText.delegate = self

    realm.objectForPrimaryKey(noteTitles, key: "id")// error here





    // Do any additional setup after loading the view.
}

这是课堂笔记代码:

 import Foundation
 import RealmSwift


class Note: Object {
    var title = ""
    var content = ""

override class func primaryKey() -> String? {
    return "id"
}

}

提前感谢您的帮助。


I have just started using Realm for a notepad app and saved the array(noteTitles) of a custom class(Note). I made it as an object, but when I use realm.objectForPrimaryKey(noteTitles, key: "id") It gives me an error: Cannot convert value of type 'Note' to expected argument type Object.Type. In the class file for note, I have made it as an object.

Here is my ViewController code:

var note: Note!
let realm = try! Realm()

@IBOutlet var noteText: UITextView!
@IBOutlet var noteTitle: UITextField!

func textViewDidEndEditing(textView: UITextView) {


    try! realm.write{

       realm.add(noteTitles)



    }

    print("editing ended")

}


override func viewDidLoad() {
    super.viewDidLoad()


    self.noteText.delegate = self

    realm.objectForPrimaryKey(noteTitles, key: "id")// error here





    // Do any additional setup after loading the view.
}

And here is the Class Note Code:

 import Foundation
 import RealmSwift


class Note: Object {
    var title = ""
    var content = ""

override class func primaryKey() -> String? {
    return "id"
}

}

Thank You in advance for help.

# Local configuration file (sdk path, etc)
local.properties

# Proguard folder generated by Eclipse
proguard/

# Log Files
*.log

# Android Studio Navigation editor temp files
.navigation/

# Android Studio captures folder
