iOS 8 中的 layoutMarginsFollowReadableWidth 错误

Question

我开发了一个在 iOS9 中运行良好的应用程序，但是如果我打开一个带有静态 UITableViewCell 的控制器，则会出现此错误：

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

我检查了是否有 'empty' 连接，但没有。

这是ViewController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
    }

}

我希望你们中的一些人知道是什么导致了这个错误。

Answer 1

我在Xcode项目中也遇到过这个问题，最后解决了。错误是："Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key layoutMarginsFollowReadableWidth.'"

原因是我在尺寸检查器选项中使用了 "Add Size Class Customization"，删除它并再次运行，错误消失了。希望对你有帮助。 As is shown in picture
