A TabBar with 6 tabs, A ViewController, A WebView

I'm begginer for swift. I want to create the web view application optimized navigation (to see commerce site).

I decide to use TabBarController(with 6 tabs) and UIWebView. And I could implement this application.

  1. TabBarController related to 6 ViewControllers
  2. 6 ViewControllers has each UIWebView(specified URI)

I could see 6 tabs like website. But I have question...

If possible, I want to use a TabBarController with 6 tab and a ViewController and a UIWebView. And when I could select a tab(in 6tabs), I want to change the url of the same UIWebView.

Please tell me how to solve this. Thanks in advance.

I think, it is not possible to have one ViewController in TabBarController, but you can have one WebView and share it between your view controllers.

  1. Create WebView in singleton style:

    class WebView: UIWebView
{
    static let sharedInstance = WebView()
}

  2. Place it on view, that will appear on screen:

    class FirstViewController: UIViewController
{
    override func viewWillAppear(animated: Bool)
    {
        view.addSubview(WebView.sharedInstance)
        WebView.sharedInstance.frame = CGRect(x: 0, y: 0, width: 320, height: 480)

       // configure it as you need: load request, setup autolayout constraints, etc..
    }
}

class SecondViewController: UIViewController
{   
    override func viewWillAppear(animated: Bool)
    {
        view.addSubview(WebView.sharedInstance)
        WebView.sharedInstance.frame = CGRect(x: 0, y: 0, width: 320, height: 480)

        // same
    }
}

// and same in each view controller
