UITableViewCell, UITextView with dynamic height

by

Use UILabel for your cell text. You can then use sizeWithFont:constrainedToSize: to calculate the height of that UILabel within each cell. For example:

#define PADDING 10.0f

- (CGFloat)tableView:(UITableView *)t heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    NSString *text = [self.items objectAtIndex:indexPath.row];
    CGSize textSize = [text sizeWithFont:[UIFont systemFontOfSize:14.0f] constrainedToSize:CGSizeMake(self.tableView.frame.size.width - PADDING * 3, 1000.0f)];

    return textSize.height + PADDING * 3;
}

The solution is quite simple and should work since iOS 7. Make sure that the Scrolling Enabled option is turned off for the UITextView inside the UITableViewCell in the StoryBoard.

Then in your UITableViewController’s viewDidLoad() set the tableView.rowHeight = UITableViewAutomaticDimension and tableView.estimatedRowHeight > 0 such as:

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.rowHeight = UITableViewAutomaticDimension
    tableView.estimatedRowHeight = 44.0
}

That’s it. UITableViewCell‘s height will be automatically adjusted based on the inner UITextView‘s height.
