In monotouch how to make status bar text color to white for ios7?

Question

For some screens status bar text color is white but for some screens it is black,So how to change it to white for all for ios7. I had use PreferedStatusBarStyle() method but it is not executing.

Just to be sure, PreferedStatusBarStyle() is not a method you call, but a method you have to override.

public partial class MyViewController : UIViewController
{
    public override UIStatusBarStyle PreferredStatusBarStyle ()
    {
        return UIStatusBarStyle.LightContent;
    }
}

Now, this only works for top-level view controllers (or the like, as a VC pushed in a UINavigationController). If you want a sub view controller to drive the status bar, override ChildViewControllerForStatusBarStyle

public partial class TopLevelViewController : UIViewController
{
    public override UIViewController ChildViewControllerForStatusBarStyle ()
    {
        return myNestedViewController.
    }
}

To be exhaustive, if the BarStyle has changed, make sure you let that fact known by calling SetNeedsStatusBarAppearanceUpdate ().

Hope it helps.
