不能在属性初始值设定项中使用实例成员'server' [英] Cannot use instance member 'server' within property initializer

问题描述

我收到此错误：无法在属性初始值设定项中使用实例成员'服务器';属性初始化程序在我的代码的这一行中'自己可用'之前运行

I'm getting this error: "Cannot use instance member 'server' within property initializer; property initializers run before 'self's available" in this line of my code

编辑

   import UIKit
import ChinoOSXLibrary

class LoginCL: UIViewController {


    @IBOutlet weak var emailField: UITextField!

    @IBOutlet weak var passField: UITextField!

    var loggedUser: LoggedUser!
    var customerId = "xxx"
    var customerKey = "xxx"
    var server = "https://api.test.chino.io/v1"

    var chino = ChinoAPI.init(hostUrl: server, customerId: customerId, customerKey: customerKey)


    override func viewDidLoad() {
        super.viewDidLoad()

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

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

我如何解决它？错误发生在这一行

how i can solve it? The error is at this line

var chino = ChinoAPI.init(hostUrl: server, customerId: customerId, customerKey: customerKey)

推荐答案

您不能使用视图控制器和属性的实例，直到初始化，所以你只需要将 ChinoAPI 初始化移动到 viewDidLoad ：

You cannot use an instance of your view controller and properties until the initialization, so you just need to move your ChinoAPI initialization toviewDidLoad:

var chino: ChinoAPI!

override func viewDidLoad() {
    super.viewDidLoad()
    chino = ChinoAPI(hostUrl: server, customerId: customerId, customerKey: customerKey)
}

另一种选择是将视图控制器中的所有硬编码值移至 ChinoAPI ，但我不确定它是否适合您的逻辑。

Another option is to move all hardcoded values from your view controller to ChinoAPI, but I'm not sure if it will fit your logic well.

此外，您可以将值移至init，如：

Also, you can just move the values to init like:

ChinoAPI.init(hostUrl: "https://api.test.chino.io/v1", customerId: "xxx, customerKey: "xxx")
