Swift 3 WebView

Question

So I just updated to the new Xcode8 and Swift3 but now my web view does not work. Here is the code I used:

UIWebView.loadRequest(webVie         


        

Answer 1

A dynamic webview class with loading :

class WebViewController : UIViewController, UIWebViewDelegate {

var url : String!
var webView : UIWebView!
var loadingView : UIActivityIndicatorView!

override func viewDidLoad() {


    let x = Int(UIScreen.main.bounds.width / 2 - 25)
    loadingView = UIActivityIndicatorView(frame : CGRect(x: x, y: 100, width: 50, height: 50))
    loadingView.activityIndicatorViewStyle = .gray

    webView = UIWebView(frame: UIScreen.main.bounds)
    webView.delegate = self
    view.addSubview(webView)
    if let url = URL(string: url) {
        let request = URLRequest(url: url)
        webView.loadRequest(request)
    }else{

        self.navigationController?.popViewController(animated: true)
    }

    view.addSubview(loadingView)
    loadingView.startAnimating()
}

func webViewDidFinishLoad(_ webView: UIWebView) {

    loadingView.removeFromSuperview()
}

static func initController() -> WebViewController {

    let vc = WebViewController()
    return vc
}   
}

///// use it

 let webvc = WebViewController.initController()
 webvc.url = "http://apple.com"
 self.navigationController?.pushViewController(webvc, animated: true)
