How to make tabbar navigate between webpages with one wkwebview?

I use wkwebview to render the web page, I have three web pages. I want to use tabbar to navigate between these three pages. I feel each wkwebview a page may take too much resource.

So I just want to use only one wkwebview to load the three-page. when touching the tab, the webpage page loaded. i.e. when tab1 clicked, the page1 loaded, tab2 clicked, the page2 loaded, same for tab3 and page3. Now I can just load a page with wkwebview, I'm new to ios.

if tabbar cannot implement this, what should I do?

If you want to something like then add UITabbar with 3 tabitem inside your ViewController and then set delegate of it with your ViewController. Now implement didSelect item method of UITabbar and load the url according the tab.

func tabBar(_ tabBar: UITabBar, didSelect item: UITabBarItem) {
    switch item.title! {
    case "First":
        self.webView.load(URLRequest(url: url1))
    case "Second":
        self.webView.load(URLRequest(url: url2))
    default:
        self.webView.load(URLRequest(url: url3))
    }
}

If you are not using two different scenes, you need to use combination of UIViewController + UIToolbar. Add your two UIBarButtonItem(s) to your toolbar. Set their action to the desired url and you are done.

You can override method handleNavBackButton() to get callback on back button.

override func handleNavBackButton() {
  if webViewData.canGoBack {
    webViewData.goBack()
  } else {
    _ = self.navigationController?.popViewController(animated: true)
  }
}

Please let me know if it works for you :)
