Name	Description
RegisterClassForHeaderFooterViewReuse(Type, NSString)	Registers a type to provide UITableViewHeaderFooterView instances for headers or footers for a specific reuse identifier.
RegisterClassForHeaderFooterViewReuse(Type, String)	Registers the `cellType` type for header or footer view reuse, keyed by the identifier `reuseIdentifier`.

RegisterClassForHeaderFooterViewReuse(Type, NSString)

Registers a type to provide UITableViewHeaderFooterView instances for headers or footers for a specific reuse identifier.

public void RegisterClassForHeaderFooterViewReuse(Type cellType, Foundation.NSString reuseIdentifier);

public void RegisterClassForHeaderFooterViewReuse(Type? cellType, Foundation.NSString reuseIdentifier);

member this.RegisterClassForHeaderFooterViewReuse : Type * Foundation.NSString -> unit

Parameters

cellType: Type

The type of a UITableViewHeaderFooterView to create when the specified reuseIdentifier is passed to DequeueReusableHeaderFooterView(String), or null to unregister the reuse identifier.

reuseIdentifier: NSString

The reuse identifier.

Remarks

Registering types with reuse identifiers helps reduce the amount of code that you have to write in your GetViewForFooter(UITableView, IntPtr) or GetViewForHeader(UITableView, IntPtr) methods. It means that your code only needs to call DequeueReusableHeaderFooterView(String) with the reuse identifier, and if there is no available header or footer view, the UITableView will create an instance of the specified type and return it.

The type that you register must provide a constructor that takes a NativeHandle parameter and needs to chain to the UITableViewHeaderFooterView(NativeHandle) constructor.
