I want to change the font size , so i use SegmentedControlRenderer , my code as below

[assembly: ExportRenderer(typeof(SegmentedControl.FormsPlugin.Abstractions.SegmentedControl), typeof(MySegmentedControlRenderer))]
namespace FormsApp.iOS
{
    class MySegmentedControlRenderer : SegmentedControlRenderer
    {
        protected override void OnElementPropertyChanged(object sender, PropertyChangedEventArgs e)
        {
            base.OnElementPropertyChanged(sender, e);
        }

        protected override void OnElementChanged(ElementChangedEventArgs<SegmentedControl.FormsPlugin.Abstractions.SegmentedControl> e)
        {
            base.OnElementChanged(e);

            if(Control !=null){
                var myFont = UIFont.SystemFontOfSize(40f);
                Control.SetTitleTextAttributes(new UITextAttributes() { Font = myFont }, UIControlState.Normal);
            }          
        }
    }
}

I can see the control shows on the screen , but OnElementChanged is never triggered.

Please correct me if my code has mistaken.

Thanks.

You got it wrong. In order for this to work, you need to derive from SegmentedControl first and create a renderer for each platform. Make sure that the View you're going to export is your custom control, i.e:

ExportRenderer(typeof(Your_Custom_Control_Here), typeof(MySegmentedControlRenderer))]

And instead of using the SegmentedControl in your XAML, you also use your Your_Custom_Control_Here
