Ios 更新到Swift 2.0时出现代码问题&引用；无法转换值..”；

我已经将Swift更新为2.0，并自动转换了代码，但我看到了一些错误，我希望修复这些错误

其中之一是：“无法将“[AnyObject]”类型的值转换为预期的参数类型“[String]”

创建此VC的目的是启动电子邮件屏幕，以帮助用户与我联系

func Lanzar电子邮件中的以下行中有错误：

mailController？.setToRecipients（收件人）

守则：

import UIKit
import MessageUI

class tuPropiaHistoriaVC: UIViewController,MFMailComposeViewControllerDelegate {

var alert: UIAlertView?
var subjectText:String?
var destinatario:AnyObject!
var mailController:MFMailComposeViewController?

@IBOutlet weak var scrollView: UIScrollView!

override func viewDidLoad() {
    super.viewDidLoad()

    //Recipients
    subjectText = "Mi historia de éxito / superación."
    destinatario = "1234@hotmail.es"

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

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


@IBAction func lanzarEmail(sender: AnyObject) {

    if(MFMailComposeViewController.canSendMail()){


        //AlertView
        alert = UIAlertView()
        alert!.addButtonWithTitle("Ok")

        mailController = MFMailComposeViewController()
        //asignar delegado al controlador de email
        mailController?.mailComposeDelegate = self




        //Completar objeto mailController

        mailController?.setSubject(subjectText!)

        var recipients = [destinatario]

        mailController?.setToRecipients(recipients)
        self.presentViewController(mailController!, animated: true, completion: nil)

    }else
    {
        let sendMailErrorAlert = UIAlertView(title: "No se puede enviar Email", message: "Por favor configura tu app Mail para poder enviar correos", delegate: self, cancelButtonTitle: "Entendido")
        sendMailErrorAlert.show()
        self.dismissViewControllerAnimated(false, completion: nil)

    }






}


func  mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {


    switch result.rawValue {

    case MFMailComposeResultCancelled.rawValue:
        //se cancelo envio
        alert!.title = "Envio cancelado"
        alert!.message = "Se canceló el envio"
        alert!.show()

    }


    mailController?.dismissViewControllerAnimated(true,

        //Clousure a ejecutar al finalizar de mostrar la vista

        completion: { () -> Void in


            //Cerrar pantalla del view base, requiere que la conexion entre pantallas sea del tipo seague

尝试将行

var destinatario:AnyObject！

更改为

var destinatario:String！

。或更改为

let destinatario=”1234@hotmail.es“

如果是常量值

mailController的方法

setToReceipents

签名看起来像

func setToRecipients（recipients:[String]）

（实际上，这是属性

var recipients:[String]

）。但您传递的是

AnyObject

的数组，而不是

String

的数组
