Resetting custom UITableViewCell height when iPhone is rotated

Question

I am overloading the delegate method -tableView:heightForRowAtIndexPath: and using -sizeWithFont:constrainedToSize: to programmatically set the height

Answer 1

It's less than optimal, but the simplest solution is to call -reloadData on the table.

A better solution would be to call -beginUpdates, -deleteRowsAtIndexPaths:withRowAnimation:, -insertRowsAtIndexPaths:withRowAnimation:, and -endUpdates or simply -reloadSections:withRowAnimation: if targeting 3.0 only. This will add animation.

Edit: And you will also need a proper tableView:heightForRowAtIndexPath:

- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    CGSize textSize = [[self textForRowAtIndexPath:indexPath] sizeWithFont:[UIFont systemFontOfSize:14] constrainedToSize:CGSizeMake([tableView frame].size.width - 20, 500)];
    return textSize.height + 13.0f;
}

(where textForRowAtIndexPath: is a method that returns the cell's text)
