How to dismiss two UIViewControllers in iOS 8?

Question

I am working on iPhone application using Objective C. As I need to dismiss two UIViewControllers at once, so I am using below code :

[self.presentingViewController.presentingViewController dismissViewControllerAnimated:YES completion:nil];

This code is working fine in iOS6 and iOS7, but it is not working in iOS8. I have checked by using breakpoint, my ViewController viewDidLoad and viewWillAppear method is calling but my view is not loading at all, so as an output, I am getting blank white screen. Can anyone please help me that for iOS8, how can I solve this problem, should I need to use presentedViewController instead of presentingViewController?

Swift code

@IBAction func goBack(sender: AnyObject) {
    var tmpController :UIViewController! = self.presentingViewController;

    self.dismissViewControllerAnimated(false, completion: {()->Void in
        println("done");
         tmpController.dismissViewControllerAnimated(false, completion: nil);
    });
}
