I am using UITableView with estimatedRowHeight and UITableViewAutomaticDimension. Also I am using NSFetchedResultsControllerDele
To solve my problem I save the cell height in the willDisplay method and in estimatedHeightForRowAt I'm retrieving the value.
var cellHeights = NSMutableDictionary()
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
override func tableView(_ tableView: UITableView, estimatedHeightForRowAt indexPath: IndexPath) -> CGFloat {
if let height = cellHeights.object(forKey: indexPath) {
return height as! CGFloat
}
return UITableViewAutomaticDimension
}
override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
cellHeights.setObject(cell.frame.size.height, forKey: indexPath as NSCopying)
}
