UITableView dynamic cell heights only correct after some scrolling

Question

I have a UITableView with a custom UITableViewCell defined in a storyboard using auto layout. The cell has several multiline UILabels.

Answer 1

none of the above solutions worked for me, what worked is this recipe of a magic: call them in this order:

tableView.reloadData()
tableView.layoutIfNeeded() tableView.beginUpdates() tableView.endUpdates()

my tableView data are populated from a web service, in the call back of the connection I write the above lines.
