提问by YouSS
I have xcode 9.1 with swift 4 and i'm unable to authenticate using webview anymore. here is my code :
我有带有 swift 4 的 xcode 9.1，我无法再使用 webview 进行身份验证。这是我的代码：
import UIKit
protocol AuthViewControllerDelegate{
func getAccessToken(_ code: String)
}
class AuthViewController: UIViewController, NSURLConnectionDelegate {
@IBOutlet weak var navItem: UINavigationItem!
@IBOutlet weak var webView: UIWebView!
var delegate: AuthViewControllerDelegate?
override func viewDidLoad() {
super.viewDidLoad()
var link: "https://home.nest.com/login/oauth2?client_id=…"
if let encodeURL = link.URLEncodedString(), let url = URL(string: encodeURL) {
webView.loadRequest(URLRequest(url: url))
}
}
override var preferredStatusBarStyle : UIStatusBarStyle {
return .lightContent
}
@IBAction func CancelPressed(_ sender: UIBarButtonItem) {
self.dismiss(animated: true, completion: nil)
}
func webView(_ webView: UIWebView, shouldStartLoadWithRequest request: URLRequest, navigationType: UIWebViewNavigationType) -> Bool {
if let url = request.url?.absoluteString, url.contains("code=") {
if let code = getQueryStringParameter(url,param: "code"){
self.dismiss(animated: true, completion: { () -> Void in
UIApplication.shared.isNetworkActivityIndicatorVisible = false
self.delegate?.getAccessToken(code)
})
}
}
return true
}
func webViewDidStartLoad(_ webView: UIWebView){
UIApplication.shared.isNetworkActivityIndicatorVisible = true
}
func webViewDidFinishLoad(_ webView: UIWebView){
UIApplication.shared.isNetworkActivityIndicatorVisible = false
}
func getQueryStringParameter(_ url: String?, param: String) -> String? {
if let url = url, let urlComponents = URLComponents(string: url), let queryItems = (urlComponents.queryItems) {
return queryItems.filter({ (item) in item.name == param }).first?.value!
}
return nil
}
}
And here is the error i'm getting in the log :
这是我在日志中遇到的错误：

And i already have this into my .plist file :
我已经将它放入我的 .plist 文件中：
<dict>
<key>NSAllowsArbitraryLoads</key>
<true/>
</dict>
NB: The same code was working perfectly with swift 3.2
注意：相同的代码与 swift 3.2 完美配合

Check if your htpps://is right, had the same problem, fixed after changing url.
检查你htpps://是否正确，有同样的问题，更改 url 后修复。
