title: Set FSCalendarAppearance delegate in iOS Xamarin Native
body: <p>Im trying to implement a calendar using FSCalendar for iOS.

  <p>I've got the calendar working but am unable to get enable appearance delegate methods (FSCalendarDelegateAppearance) in order to customise individual cells.</p>
  
  <p>Also, though I am able to create CalendarAppearance object, I am unable to attach it to the calendar. Any help is appreciated. </p>
  
  <p>Thanks</p>
