Make UITableView not scrollable and adjust height

Question

I'm embedding a UITableView inside of another UIScrollView. I only want the UIScrollView to scroll, not the UITableView, so I want to disable the scrolling in UITableView, as well as expand the contentHeight for the UITableView to accommodate all dynamic at once.

How would I go about doing this?

Answer 1

UITableView is a scroll view. While you are not supposed to nest UIScrollviews, you can disable scrolling of the the table view.

Answer 2

Set tableView scrolling property to false.

First Approach:

1. Create a subclass for tableView and override intrinsicContentSize.

        class MyOwnTableView: UITableView {
       override var intrinsicContentSize: CGSize {
           self.layoutIfNeeded()
           return self.contentSize
       }
   
       override var contentSize: CGSize {
           didSet{
               self.invalidateIntrinsicContentSize()
           }
       }
   
       override func reloadData() {
           super.reloadData()
           self.invalidateIntrinsicContentSize()
       }
   }
   

2. In Interface builder change the class of your tableView to MyOwnTableView (subclass UITableView).

3. Set automatic row height for the table view.

       tableView.estimatedRowHeight = 60.0;
       tableView.rowHeight = UITableViewAutomaticDimension;
   

Second Approach: 1. Create a height constraint with any value for tableView and connect an IBOutlet that sets the tableView height.

2. Set the height constraint's constant to tableView.contentSize.height after reloading the data.

   self.tableViewHeight.constant = self.tableView.contentSize.height
