UIWindow window;
//
// This method is invoked when the application has loaded and is ready to run. In this
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
// create a new window instance based on the screen size
window = new UIWindow (UIScreen.MainScreen.Bounds);
// If you have defined a root view controller, set it here:
// window.RootViewController = myViewController;
// make the window visible
window.MakeKeyAndVisible ();
return true;
}
