Application developers who override this class in order to provide additional layout parameters should also override UICollectionReusableView.ApplyLayoutAttributes to apply them.
In order to get a layout attributes object for a subclass of this class, you must call UICollectionViewLayoutAttributes.CreateForCell`1 and specify the type of the subclass, like this:
C# Example
// A custom UICollectionViewLayoutAttributes class with one extra property
public class CustomCollectionViewLayoutAttributes : UICollectionViewLayoutAttributes {
public int SomeProperty { get; set; }
public override NSObject Copy ()
{
// It is required to override Copy, iOS will call this method to clone your object.
var copy = (CustomCollectionViewLayoutAttributes) base.Copy ();
copy.SomeProperty = SomeProperty;
return copy;
}
}
public class CircleLayout : UICollectionViewLayout {
public override UICollectionViewLayoutAttributes LayoutAttributesForItem (NSIndexPath path)
{
var attributes = UICollectionViewLayoutAttributes.CreateForCell<CustomCollectionViewLayoutAttributes> (path);
attributes.SomeProperty = 1;
return attributes;
}
}
MonoTouch.UIKit.UICollectionViewLayoutAttributes implements MonoTouch.UIKit.IUIDynamicItem and thus can be used with UI Dynamics.
