Question

I have a custom UITableViewCell that takes up a portion of the screen. However, when there is only one row of data, I’d like the UITableView (that I dropped in with IB), to shrink and only show the one row. Is there a way for the UITableView to redraw itself? Thanks.

You can set the tableView height using the following code:

CGRect newFrame = tableView.frame;

frame.size.height = newHeight;

tableView.frame = newFrame;

If you want to animate the height change you need to do:

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationBeginsFromCurrentState:YES];
[UIView setAnimationCurve:UIViewAnimationCurveLinear];
[UIView setAnimationDuration:0.5];

CGRect newFrame = tableView.frame;

frame.size.height = newHeight;

tableView.frame = newFrame;

[UIView commitAnimations];

You can put all of the above code in a method which you can call when your numberOfRowsInSection data source method returns a value of 1.
