Could you please specify which kind of controls you are using? If you want to consume a list view with a custom appearance you could create a custom view cell and then configure the controls there.
Follow this documentation to construct your list view: https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/listview/
Do you mean you are consuming UITableView? Could you give more description?
i.e. What effect do you want to achieve, post the related code to help us understand the issue.
