Description
According to the documentations https://docs.microsoft.com/en-us/xamarin/xamarin-forms/app-fundamentals/custom-renderer/renderers#views Xamarin Forms' CollectionView should be of type UICollectionView under iOS. However when implementing a Customrenderer with the help of CollectionViewRenderer the Control is of type UICollectionViewControllerWrapperView. It is difficult or can just be done by tricks to get the actual UICollectionView to manipulate the rendering.
Steps to Reproduce
- Create a new Xamarin Forms app
- Create a class inheriting from CollectionView
- In the iOS project create a custom renderer inheriting from CollectionViewRenderer
- In the OnElementChanged (Or somewhere you want) print/see the type of Control
Expected Behavior
Control of an iOS CollectionViewRenderer is of type UICollectionView
Actual Behavior
Control of an iOSCollectionViewRenderer is of type UICollectionViewControllerWrapperView
