title: How to change the title of Timepicker and localization in custom renderer
body: <p>I have Xamarin forms time picker following custom renderer for IOS</p>
  
  <pre><code>[assembly: ExportRenderer(typeof(TimePicker), typeof(Time24PickerRenderer))]
  namespace LabOraTimeStamp.iOS.Renderers
  {
      public class Time24PickerRenderer:TimePickerRenderer
      {
          protected override void OnElementChanged(ElementChangedEventArgs&lt;TimePicker&gt; e)
          {
              base.OnElementChanged(e);
              var timePicker = (UIDatePicker)Control.InputView;
              timePicker.Locale = new NSLocale("no_nb");
  
              //Get the Done button
              var toolbar = (UIToolbar)Control.InputAccessoryView;
              var doneBtn = toolbar.Items[1];
  
              //Set the Done to OK
              doneBtn.Title = "OK";
          }
      }
  }
  </code></pre>
  
  <p>I wanted to change the default "done" to "Ok".</p>
  
  <p>1) How can I do that? the line mentioned above for setting the title does not affect anything.</p>
  
  <p>2) I already implemented localization for xamarin forms.I just wanted to use existing Resx values from custom renderer to show the string for appropriate culture.How can I achieve that?</p>
