extension methods are part of C#, not specific to MonoTouch. There are
several great overviews on MSDN and elsewhere you might want to read
As the name implies, they extend an existing class my adding methods to
them. In this case, the class that is being extended is UIView. So any
object that is an instance of UIView (like a UITableViewCell) should have
the new method added to it.
in your example, you want to call
cell.SetAccessibilityLabel("text");
