ios - 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，而屏幕模式是 940 x 680。如何设置正确的分辨率，因为我想针对 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 的分辨率。

我在哪里可以获得正确的界限，或者为什么界限不是应该的？

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;
        }
