push viewController and keep the webView state ios

Question

The first view of my app is HomeViewController which contain a webView. From an other view in the app I want to navigate (or push) my HomeViewController and in the same time I want to keep the first state of the webView.

How can I store and reuse the webView content?

Other possibility would be to store the viewController state and re-use it again. Any idea would be helpful?

Thanks.

Answer 1

I solved it by doing this.

class HomeViewController: UIViewController, UIWebViewDelegate {

class var instance: HomeViewController {

    struct Static {
        static var instance: HomeViewController?
        static var token: dispatch_once_t = 0
    }
    dispatch_once(&Static.token) {
        Static.instance = HomeViewController()
    }
    return Static.instance!
    }
..............................

}

And when I want to push again my HomeViewController I do this:

    self.navigationController?.pushViewController(HomeViewController.instance, animated: true)

As simple as that.
