Question

在设置如下的联系论坛后，我收到以下错误。有没有改变/贬值的Xcode没有捕获或我今天早上只是累了？

“实例方法'mailComposeController（controller：didFinishWithResult：error :)'几乎匹配协议'MFMailComposeViewControllerDelegate'的可选要求'mailComposeController（_：didFinishWith：error :)'” - 第46行

“候选人有非匹配类型”（MFMailComposeViewController，MFMailComposeResult，NSError？） - ＆gt;（）'“ - 第46行

“make'mailComposeController（controller：didFinishWithResult：error :)'私有化，以此来警告” - 第46行

“使用未解析的标识符'MFMailComposeCancelled” - 第50行

“使用未解析的标识符'MFMailComposeResultFailed'” - 第53行

“使用未解析的标识符'MFMailComposeResultSaved'” - 第56行

“使用未解析的标识符'MFMailComposeResultSent'” - 第59行

import Foundation

class Contact : UIViewController, MFMailComposeViewControllerDelegate {
@IBOutlet weak var WOLMenu: UIBarButtonItem!
@IBOutlet var NameField: UITextField!
@IBOutlet var EmailField: UITextField!
@IBOutlet var PhoneField: UITextField!
@IBOutlet var MessageField: UITextField!




override func viewDidLoad() {

    self.view.addGestureRecognizer(self.revealViewController().panGestureRecognizer())

}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
}

@IBAction func Send(sender: AnyObject) {
    let toRecipients = ["s jobs @ apple . com"]

    let mc: MFMailComposeViewController = MFMailComposeViewController()

    mc.mailComposeDelegate = self

    mc.setToRecipients(toRecipients)
    mc.setSubject(NameField.text!)

    mc.setMessageBody("Name: \(NameField.text!) \n\nEmail: \(EmailField.text!) \n\nPhone: \(PhoneField.text!) \n\nMessage: \(MessageField.text!)", isHTML: false)
    self.present(mc, animated: true, completion: nil)
}

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

    switch result.rawValue {
    case MFMailComposeCancelled.rawValue:
        print("CANCELED")

    case MFMailComposeResultFailed.rawValue:
        print("Failed")

    case MFMailComposeResultSaved.rawValue:
        print("Saved")

    case MFMailComposeResultSent.rawValue:
        print("Sent")

    default:
        break

    controller.dismiss(animated: true, completion: nil)
}
}

override var prefersStatusBarHidden: Bool {
    return true
}
}

此外，代码来自Apple的文档必须更新 MFMailComposeViewController Documention

mfmailcomposeviewcontroller给出了多个错误
