xamarin.ios - How to assign Background Image to an entry in xamarin forms for ios -

i trying add background image entry in xamarin forms , wrote code rendering in ios , android. android working , ios not working. here sharing rendering code ios:

[assembly: exportrenderer (typeof(extendedusername), typeof(renderingentryuname))] namespace ifind.ios { public class renderingentryuname: entryrenderer {     // override onelementchanged method can tweak renderer post-initial setup     protected override void onelementchanged(elementchangedeventargs<entry> e)     {         base.onelementchanged(e);          if (control != null) {              control.textalignment=uitextalignment.center;             uiimage img=uiimage.fromfile("images/newimg.jpg");             control.background=img          }     }  } }              

by default uitextentry used forms entry have border style set uitextborderstyle.roundedrect , background ignored.

set border style none , image show up:

if (control != null) {    control.borderstyle = uitextborderstyle.none;    control.textalignment=uitextalignment.center;    uiimage img=uiimage.fromfile("images/newimg.jpg");    control.background=img } 

if value set uitextborderstyleroundedrect style, custom background image associated text field ignored.
