xamarin.ios 代码中设置启动的 Storyboard

AppDelegate 添加如下代码

uinavroot 为故事版 UINavigationController 中的定义，需要在 xcode ide中定义。

public override bool FinishedLaunching (UIApplication application, NSDictionary launchOptions)

{

Window = new UIWindow (UIScreen.MainScreen.Bounds);

UIStoryboard sb = UIStoryboard.FromName ("MainStoryboard",null);

UINavigationController nai = sb.InstantiateViewController ("uinavroot") as UINavigationController;

Window.RootViewController = nai;

Window.MakeKeyAndVisible ();

return true;

}
