layoutMarginsFollowReadableWidth错误的iOS 8

问题描述：

我已经开发了一个应用，该应用的工作相当不错，在iOS版9，但如果我打开一个控制器，一个静态的UITableViewCell有这样的错误：layoutMarginsFollowReadableWidth错误的iOS 8

Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key layoutMarginsFollowReadableWidth.'

我检查，如果有一个'空'的连接，但没有。

这是视图控制器的代码：

class KontaktController: UITableViewController, MFMailComposeViewControllerDelegate{ 

    @IBOutlet weak var mapView: MKMapView! 
    @IBOutlet weak var openMenu: UIBarButtonItem! 

    let mailController = MFMailComposeViewController() 

    override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat { 
     switch UIDevice.currentDevice().userInterfaceIdiom { 
     case .Phone: 
      // It's an iPhone 
      switch indexPath.section{ 
      case 0: 
       return 150 
      case 3: 
       if indexPath.row == 0{ 
        return 150 
       } 
       else{ 
        return 100 
       } 
      default: 
       return 53 
      } 
     case .Pad: 
      // It's an iPad 
      switch indexPath.section{ 
      case 0: 
       return 250 
      case 3: 
       if indexPath.row == 0{ 
        return 250 
       } 
       else{ 
        return 100 
       } 
      default: 
       return 53 
      } 
     default: 
      print("OH ?!") 
      // Uh, oh! What could it be? 
     } 

     return 10 
    } 


    @IBAction func kontaktirenSieUnsPressed(sender: AnyObject) {

    @IBAction func adressPressed(sender: UIButton) { 

     switch sender.tag{ 
     case 0: 
      let url: NSURL = NSURL(string: "tel://004965185730")! 
      UIApplication.sharedApplication().openURL(url) 
     case 2: 
      let mailComposeViewController = configuredMailComposeViewController() 
      if MFMailComposeViewController.canSendMail() {

    // Send email: 
    func configuredMailComposeViewController() -> MFMailComposeViewController { 
     let mailComposerVC = MFMailComposeViewController() 
     mailComposerVC.mailComposeDelegate = self // Extremely important to set the --mailComposeDelegate-- property, NOT the --delegate-- property 

     mailComposerVC.setToRecipients(["[email protected]"]) 

     mailComposerVC.setMessageBody("Gesendet von der Dachdecker Kremer App.", isHTML: false) 

     return mailComposerVC 
    } 

    func showSendMailErrorAlert() { 
     let sendMailErrorAlert = UIAlertController(title: "E-mail senden fehlgeschlagen", message: "Ihr iPhone kann leider keine Mails senden. Gehen Sie zu Einstellungen/Mail, um den Fehler zu beheben.", preferredStyle: .Alert) 
     sendMailErrorAlert.addAction(UIAlertAction(title: "OK", style: .Cancel, handler: nil)) 
     self.presentViewController(sendMailErrorAlert, animated: true, completion: nil) 
    } 

    // MARK: MFMailComposeViewControllerDelegate Method 
    func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) { 
     controller.dismissViewControllerAnimated(true, completion: nil) 
    } 
    @IBAction func route(sender: AnyObject) { 
     let targetURL = NSURL(string: "http://maps.apple.com/?daddr=49.743056,6.621047&dirflg=d&t=h") 
     UIApplication.sharedApplication().openURL(targetURL!) 
    } 

}

我希望你们中有些人是什么原因造成这个错误的想法。

答

我也在Xcode项目中遇到过这个问题，最后解决了它。错误是：“终止应用程序由于未捕获的异常‘NSUnknownKeyException’，原因：‘[setValue方法：forUndefinedKey：]：这个类不是密钥值编码兼容的关键layoutMarginsFollowReadableWidth’。”

其原因是我在大小检查器选项中使用“添加大小类定制”，将其删除并再次运行，错误消失。希望对你有帮助。 As is shown in picture
