If you want to reload specific cells, use UITableView's reloadRowsAtIndexPaths:withRowAnimation: method. For example, if you want to reload the cell at row 20 in section 0 and the cell at row 4 in section 2 without an animation:

[cell reloadRowsAtIndexPaths:[NSArray arrayWithObjects:
                               [NSIndexPath indexPathForRow:20 inSection:0],
                               [NSIndexPath indexPathForRow:4 inSection:2],
                               nil]
            withRowAnimation:UITableViewRowAnimationNone];

If you want to reload all the cells in the table view, then use UITableView's reloadData method (but be aware of the performance implications):

[tableView reloadData];

Alternatively, if you just want to redraw a cell (rather than reloading it in order to update its information), you can use UIView's setNeedsDisplay method:

[[cell view] setNeedsDisplay];

If your data has been updated you can refresh the view by sending the reloadData message to your tableView:

[myTableView reloadData];
