iOS adds programming interfaces to the NSIndexPath class of the Foundation framework to facilitate the identification of rows and sections in UITableView objects. The API consists of a class method and two properties. The indexPathForRow:inSection: method creates an NSIndexPath object from row and section index numbers.
