I have a UITableView with cells containing variable-height UILabels. I am able to calculate the minimum height the label needs to be using sizeWithFont:constrainedToSize:lineBreakMode:, which works fine when the table view is first loaded. When I rotate the table view the cells become wider (meaning there are fewer lines required to display the content). Is there any way I can have the height of the cells redetermined by the UITableView during the orientation change animation or immediately before or after? Thank you.

    Your UITableViewController can implement the tableView:heightForRowAtIndexPath: method to specify the row height for a particular row, and it can look at the current orientation ([[UIDevice currentDevice] orientation]) to decide what height to return.

    To make sure tableView:heightForRowAtIndexPath: gets called again when the orientation changes, you’ll probably need to
    detect the orientation change as described in this question, and call [tableView reloadData].
