Add button on top of UITableViewController (Swift)

Question

I am trying to add a button ontop of a uitableview controller table view. The view controller has a navigation controller and static cells, which is why it is a uitableviewcontr

Answer 1

I did something similar with UITableViewController and a static datasource. I added the button in the footerview of my tableview.

To make it align to the bottom of the screen i needed this code in my viewcontroller:

override func viewWillAppear(animated: Bool) {
        super.viewWillAppear(animated)

        // Make footerview so it fill up size of the screen
       // The button is aligned to bottom of the footerview 
       // using autolayout constraints
        self.tableView.tableFooterView = nil
        self.footerView.frame = CGRectMake(0, 0, self.view.frame.size.width, self.tableView.frame.size.height - self.tableView.contentSize.height - self.footerView.frame.size.height)
        self.tableView.tableFooterView = self.footerView
    }

In short, I resize the footerview to take up all the remaining space after the contentsize of the table view is removed. Since the button is aligned to the bottom of the footerView with autolayout, it will stay in the bottom of the screen.
