Table View Scrolling and Layout
A UITableView is a UIScrollView, so everything you already know about scroll views is applicable (Chapter 20). In addition, a table view supplies two convenience scrolling methods:
-
scrollToRowAtIndexPath:atScrollPosition:animated: -
scrollToNearestSelectedRowAtScrollPosition:animated:
The scrollPosition parameter is as for selectRowAtIndexPath:..., discussed earlier in this chapter.
The following UITableView methods mediate between the table’s bounds coordinates on the one hand and table structure on the other:
-
indexPathForRowAtPoint: -
indexPathsForRowsInRect: -
rectForSection: -
rectForRowAtIndexPath: -
rectForFooterInSection: -
rectForHeaderInSection:
The table’s header and footer are views, so their coordinates are given by their frames.
