尝试代码：

    override func viewDidLoad() {
        super.viewDidLoad()
    }

    func addView(/*param    */) {
        // do something
    }

    // when push to UIViewControllerB set install for viewcontrollerA
    private func goToScreenB(){
        let viewB = UIViewControllerB()
        viewB.viewcontrollerA = self
        self.navigationController?.pushViewController(viewB, animated: true)
    }
}


class UIViewControllerB: UIViewController {
//    In UIViewControllerB create a install of UIViewControllerA
    var viewcontrollerA : UIViewControllerA?
    override func viewDidLoad() {
        super.viewDidLoad()
    }
    @IBAction func button_complate(sender: AnyObject) {
        self.viewcontrollerA?.addView()
    }
