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

Add a constraint for all content within a table view custom cell, then estimate table view row height and set row hight to automatic dimension with in a viewdid load :

    override func viewDidLoad() {
    super.viewDidLoad()

    tableView.estimatedRowHeight = 70
    tableView.rowHeight = UITableViewAutomaticDimension
}

To fix that initial loading issue apply layoutIfNeeded method with in a custom table view cell :

class CustomTableViewCell: UITableViewCell {

override func awakeFromNib() {
    super.awakeFromNib()
    self.layoutIfNeeded()
    // Initialization code
}
}
