How to show page title/title bar in iOS

Hi,

Ive tried the below code to show page title in content page along with a grid. The grid works for me but I dont see the title bar as in the picture (Settings).

public ContentPage MainPage () {

    Grid grid = new Grid
    {
        Rowdefinitions
        colsdefinitions

        //Added few children to grid

    }

    var mainPage = new ContentPage {

        Title = "MyTitle",
        Content = grid
    };

    return mainPage;

}

Could someone tell me where Im going wrong?
