Resizing UITableView to fit content

Question

I am creating an app which will have a question in a UILabel and a multiple choice answers displayed in UITableView, each row showing a multiple choice. Questions and answers will vary, so I need this UITableView to be dynamic in height.

I would like to find a sizeToFit work around for the table. Where the table's frame is set to the height of all it's content.

Can anyone advise on how I can achieve this?

Answer 1

Actually I found the answer myself.

I just create a new CGRect for the tableView.frame with the height of table.contentSize.height

That sets the height of the UITableView to the height of its content. Since the code modifies the UI, do not forget to run it in the main thread:

dispatch_async(dispatch_get_main_queue(), ^{
        //This code will run in the main thread:
        CGRect frame = self.tableView.frame;
        frame.size.height = self.tableView.contentSize.height;
        self.tableView.frame = frame;
    });
