使用单元格大小自动布局调整tableview框架的大小以适合动态内容

Question

When I resize my tableView , content is cut off because contentSize seems to be determined by tableView.estimatedRowHeight = 18 .

The actual contentSize of the tableView (adjusted for autolayout) is larger than sizeToFit() thinks it is.

How do I tell sizeToFit() the correct size of my tableView contents?

 tableView.frame = CGRectMake( 0, self.scrollView.frame.size.height + 18, self.view.frame.size.width, 350 )
 tableView.estimatedRowHeight = 18
 tableView.rowHeight = UITableViewAutomaticDimension

 self.view.addSubview(self.tableView)
 tableView.sizeToFit()

You don't. The table view, as a view, knows nothing of how many rows it has or even that you think it should be the height of its rows. (It can't read your mind.) You must calculate its height yourself based on the the number of rows and their heights.
