UICollectionViewController F＃

Question

我正在尝试在F＃中实现以下内容：

    public class SimpleCollectionViewController : UICollectionViewController
{
    static NSString animalCellId = new NSString ("AnimalCell");

    public override void ViewDidLoad ()
    {
        base.ViewDidLoad ();

        CollectionView.RegisterClassForCell (typeof(AnimalCell), animalCellId);

    }

但是我不知道如何访问行中的基础CollectionView：

 CollectionView.RegisterClassForCell (typeof(AnimalCell), animalCellId);

这是我的F＃代码：

[<Register ("LandlordHome")>]
type LandlordHome (handle:IntPtr) as x =
    inherit UICollectionViewController (handle)

    let NSString animalCellId = new NSString("AnimalCell")

    override x.ViewDidLoad () =
        base.ViewDidLoad ()

        CollectionView.RegisterClassForCell(typeof(AnimalCell), animalCellId)   

然而，这会引发错误The value, namespace, type or module 'CollectionView' is not defined. Maybe you want one of the following: Collections CoreLocation UICollectionView (FS0039)
