    text
    copied!<p>My app had the default MainWindow.xib with a NavigationController in it. Now I recently switched it to a xib-less main window and RootViewController (subclass of UIViewController) similar to the example provided at the bottom of <a href="http://monotouch.net/Tutorials/HelloiPhone" rel="nofollow">HelloiPhone</a>:</p> <p>My Main.cs:</p> <pre><code>namespace MyApp { public class Application { static void Main(string[] args) { UIApplication.Main(args, null, "MyApp.AppDelegate"); } } public class AppDelegate : UIApplicationDelegate { UIWindow window; // This method is invoked when the application has loaded its UI and its ready to run public override bool FinishedLaunching(UIApplication app, NSDictionary options) { RootViewController rootViewController = new RootViewController(); UINavigationController navigationController = new UINavigationController(rootViewController); navigationController.LoadView(); navigationController.NavigationBar.BarStyle = UIBarStyle.Black; window = new UIWindow(UIScreen.MainScreen.Bounds); window.AddSubview(navigationController.View); window.MakeKeyAndVisible(); return true; } // This method is required in iPhoneOS 3.0 public override void OnActivated(UIApplication app) { } public override void WillTerminate(UIApplication app) { //Save data here } } } </code></pre> <p>My Info.plist:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"&gt; &lt;plist version="1.0"&gt; &lt;dict&gt; &lt;key&gt;UILaunchImageFile&lt;/key&gt; &lt;string&gt;images/logo_320x480.png&lt;/string&gt; &lt;key&gt;UIStatusBarStyle&lt;/key&gt; &lt;string&gt;UIStatusBarStyleBlackOpaque&lt;/string&gt; &lt;key&gt;UISupportedInterfaceOrientations&lt;/key&gt; &lt;array&gt; &lt;string&gt;UIInterfaceOrientationPortrait&lt;/string&gt; &lt;string&gt;UIInterfaceOrientationPortraitUpsideDown&lt;/string&gt; &lt;/array&gt; &lt;/dict&gt; &lt;/plist&gt; </code></pre> <p>On the simulator, everything seems well. At first, the launching image is displayed and finally the rootView appears after a few seconds.</p> <p>However, when deploying to the device (iPod touch), the rootView won't display. Instead, the screen turns to white after the launching image. (Status bar at the top is still there)</p> <p>Is there something wrong with that approach? Am I missing something?</p>
