UITableViewDelegate Class

Definition

Namespace:: UIKit

Assembly:: Xamarin.iOS.dll

A class that receives notifications from a UITableView. MonoTouch developers should generally use UITableViewSource instead of this class.

[Foundation.Protocol]
[Foundation.Register("UITableViewDelegate", false)]

Remarks

Implementing UITableView often requires subclasses of both UITableViewDataSource and UITableViewDelegate to provide data and behavior for the table view. MonoTouch provides a single class - UITableViewSource - so that only one class needs to be implemented.

The UITableViewDelegate class methods provide a table view with the ability to manage selection, configure section headers and footers, delete and reorder cells and control the editing menu.

UITableViewDelegate(IntPtr)	A constructor used when creating managed representations of unmanaged objects; Called by the runtime.
