UITableView Automatic Dimension Not Working Correctly

Question

I have a tableview that is getting populated with data from Firebase. However, when resizing the tableview using automatic dimension, some text is shown getting cut off.

Here is my Storyboard with constraints set to top, bottom, right, and left.

It is working fine when there is not alot of text as shown here.

However, when I fill the cell with alot of text this occurs.

Here is the code that I am currently using.

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        if (tableView == questInformationTableView) {
            return 50
        }
        else if (tableView == questWalkthroughTableView) {

            return UITableView.automaticDimension
        }

        return 0
    }
    override func viewDidLoad() {
          super.viewDidLoad()
          questWalkthroughTableView.estimatedRowHeight = 250
          questWalkthroughTableView.rowHeight = UITableView.automaticDimension
        }

    func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
         return UITableView.automaticDimension
        }

I have also set numberOfLines to 0 and set the label to .sizeToFit()

Answer 1

Don't make the bottom constraint greater than or equal to just set it like the top constraint. Take away the estimatedHeightForRowAt and heightForRowAt functions. Your view did load declarations are sufficient. When you reload data also call self.view.layoutIfNeeded

Answer 2

I usually set the automatic height dimension and then do a reload in the viewDidLoad like this

override func viewDidLoad() {
    super.viewDidLoad()

    tableView.rowHeight = UITableViewAutomaticDimension
    tableView.estimatedRowHeight = 44

    tableView.reloadData()   
}

Answer 3

Suggest to check

1. automatic row height is enabled inside the table cell

2. check if the label is expandable and its bottom constraint is set to superview. Adding screenshot showing list of constraints of a sample cell I am using with dynamic height.

3. Even if this doesn't fix your issue, suggest to reset all constraints and set it again for your cell.

Answer 4

For a similar issue, I removed the tableView.estimatedRowHeight assignment and kept tableView.rowHeight = UITableView.automaticDimension and everything started working. Only seemed to be an issue on iPad though.
