Dynamic Height Issue for UITableView Cells (Swift)

Question

Dynamic text of variable length are being injected into tableview cell labels. In order for the tableview cells\' heights to be dynamically sized, I have implemented in

Answer 1

SWIFT 3

tableView.rowHeight = UITableViewAutomaticDimension
tableView.estimatedRowHeight = 160

AND!!! In storyBoard: You HAVE TO set TOP & BOTTOM constraints for your Label. Nothing else.

Answer 2

Swift 5 Enjoy

tablev.rowHeight = 100
tablev.estimatedRowHeight = UITableView.automaticDimension


func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = self.tablev.dequeueReusableCell(withIdentifier: "ConferenceRoomsCell") as! ConferenceRoomsCell
    cell.lblRoomName.numberOfLines = 0
    cell.lblRoomName.lineBreakMode = .byWordWrapping
    cell.lblRoomName.text = arrNameOfRooms[indexPath.row]
    cell.lblRoomName.sizeToFit()
    return cell
}

Answer 3

I use these

func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

    return 100
}

Answer 4

You should just set all constraints for TOP, BOTTOM and HEIGHT for each object on cell view/views and remove exists middle Y position if have. Because where you didn't this, puts artifacts on another views.

Answer 5

I had also got this issue initially, I had resolved my issue from this code try avoiding the use of self.tableView.reloadData() instead of this code for dynamic height

[self.tableView reloadSections:[NSIndexSet indexSetWithIndex:0] withRowAnimation:UITableViewRowAnimationFade];

Answer 6

For Swift 4.2

@IBOutlet weak var tableVw: UITableView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Set self as tableView delegate
    tableVw.delegate = self

    tableVw.rowHeight = UITableView.automaticDimension
    tableVw.estimatedRowHeight = UITableView.automaticDimension
}

// UITableViewDelegate Method 
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {

    return UITableView.automaticDimension
}

Happy Coding :)
