Answer 1

Well, you could just call the reloadData method of your UITableView. It will only refresh visible cells. There's also reloadRowsAtIndexPaths:withRowAnimation in OS 3.0+

The easiest approach if you don't have special needs would be: (assuming myTableView has a pointer to your UITableView)

NSTimeInterval someDelay = 5; // seconds
[myTableView performSelector:@selector(reloadData) withObject:nil
    afterDelay:someDelay];

If your ViewController could disappear before the performSelector fires, be safe and call:

[NSObject cancelPreviousPerformRequestsWithTarget:myTableView
    selector:@selector(reloadData) object:nil];
