Customizing Headers and Footers
Sectioned table views are extremely customizable. Both the tableHeaderView property and the related tableFooterView property can be assigned to any type of view, each with its own subviews. So you might add labels, text fields, buttons, and other controls to extend the table’s features.
Headers and footers aren’t just one each per table. Each section offers a customizable header and footer view as well. You can alter heights or swap elements out for custom views. The optional tableView:heightForHeaderInSection: (or the sectionHeaderHeight property) and tableView:viewForHeaderInSection: methods let you add individual headers to each section. Corresponding methods exist for footers as well as headers.
