ios - How can I add a tabbed menu to a carousel view in Xamarin forms? -

i trying implement interface there 5 pages can swiped , dragged between can change page tapping on tabbed bar @ bottom.

i writing custom renderer carouselpage can not add tabbed bar @ bottom because ios uitabbar requires , array of uiviewcontrollers switch between , have access pages.

this have tried far:

[assembly: exportrenderer (typeof (extendedcarouselpage), typeof (extendedcarouselpagerenderer))]  namespace customrenderer.ios {     public class extendedcarouselpagerenderer : carouselpagerenderer     {         protected uitabbar tabbar;          protected override void onelementchanged (visualelementchangedeventargs e)         {                 base.onelementchanged (e);                  tabbar = new uitabbar (new cgrect (0, this.view.frame.height * 0.9, this.view.frame.width, this.view.frame.height * 0.1));                 tabbar.items = new uitabbaritem[]{                         new uitabbaritem("hello",uiimage.fromfile("homeicon.png"),uiimage.fromfile("homeiconblue.png")),                         new uitabbaritem("world", uiimage.fromfile("homeicon.png"),uiimage.fromfile("homeiconblue.png"))                 };                  tabbar.bounds = new cgrect (0, this.view.frame.height * 0.9, this.view.frame.width, this.view.frame.height * 0.1);                 tabbar.frame = new cgrect (0, this.view.frame.height * 0.9, this.view.frame.width, this.view.frame.height * 0.1);                  this.nativeview.addsubview(tabbar);         }     } } 

the problem can't find lot of guides on writing more complex custom renderers. there plenty xamarin ios lot of code not apply custom renderer.
