UIScreen.MainScreen.Bounds是480x320但应该更高

Question

我想知道为什么UIScreen.MainScreen.Bounds是480 x 320，当屏幕模式是940 x 680时。如何设置正确的分辨率，因为我想要定位iPhone5。我已将模拟器设置为iPhone 5.

我的屏幕看起来不像我想要的，我需要测试iPhone 5分辨率。

我在哪里获得适当的界限或为什么界限不是它们应该是什么？

这是我的appdelegate代码

public override bool FinishedLaunching (UIApplication app, NSDictionary options)
        {
            // create a new window instance based on the screen size
            window = new UIWindow (UIScreen.MainScreen.Bounds);

            StartScreen homeScreen = new StartScreen();

            //add home screen to navgation controller
            // becomes the top most screen
            this.rootNavigationController = new UINavigationController();
            this.rootNavigationController.NavigationBarHidden = true;
            this.rootNavigationController.PushViewController(homeScreen, false);


            // set the root view controller on the window.  the nav controller witll handle the rest
            this.window.RootViewController = this.rootNavigationController;

            // If you have defined a view, add it here:
            // window.AddSubview (navigationController.View);

            // make the window visible
            window.MakeKeyAndVisible();

            return true;
        }
