ios - StoryBoard.InstantiateViewController 给出 "Unknown class testController in Interface Builder file"

Question

我正在处理 Xamarin IOS/monotouch 项目。 一段时间以来我一直被这个错误所困。这些是代码行

var prfc = this.Storyboard.InstantiateViewController ("testController") as testController;
            if (prfc != null) {
                this.PresentViewController(prfc,false,null);}

我尝试重命名 viewcontroller、清理和构建解决方案、删除 viewcontroller 并添加一个新的名称 我确保所有拼写都正确，我有相同的 Viewcontroller 名称、StoryBoardID 和 Restoration ID。这就是我在 Designer 部分类中注册我的 View Controller 的方式

[Register ("testController")]
partial class testController

这是我的 appdelegate.cs 代码 `[Register ("AppDelegate")] public partial class AppDelegate : UIApplicationDelegate {//类级声明 UIWindow 窗口； public static UIStoryboard Storyboard = UIStoryboard.FromName ("MainStoryboard", null);公共(public)静态 UIViewController initialViewController；公共(public)覆盖 UIWindow 窗口 { 得到;放;

`[Register ("AppDelegate")] public partial class AppDelegate : UIApplicationDelegate { // class-level declarations UIWindow window; public static UIStoryboard Storyboard = UIStoryboard.FromName ("MainStoryboard", null); public static UIViewController initialViewController; public override UIWindow Window { get; set; }
// This method is invoked when the application is about to move from active to inactive state.
// OpenGL applications should use this method to pause.
public override void OnResignActivation (UIApplication application)
{
}

// This method should be used to release shared resources and it should store the application state.
// If your application supports background exection this method is called instead of WillTerminate
// when the user quits.
public override void DidEnterBackground (UIApplication application)
{
}

// This method is called as part of the transiton from background to active state.
public override void WillEnterForeground (UIApplication application)
{
}

// This method is called when the application is about to terminate. Save data, if needed.
public override void WillTerminate (UIApplication application)
{
}
public override void FinishedLaunching (UIApplication application)
{
    window = new UIWindow (UIScreen.MainScreen.Bounds);

    initialViewController = Storyboard.InstantiateInitialViewController () as UIViewController;

    window.RootViewController = initialViewController;
    window.MakeKeyAndVisible ();
    return ;
}

}`

我已经尝试了所有的可能性，但无法解决这个问题。我添加到 Storyboard 中的每个新 View Controller 都会发生此错误。当我调用 InstantiateViewController 时，我得到一个空值。我试过清理和重建。它适用于模拟器，但不适用于设备

@orkenstein 指出了这个问题。我的目标是 7.1，而在 7.0 设备上进行测试
