Swift 3 WebView
所以我刚刚更新到新的Xcode8和Swift3但现在我的networking视图不起作用。 这是我使用的代码：
UIWebView.loadRequest(webView)(NSURLRequest(URL: NSURL(string: "http://hardwirestudios.com")!))
现在给我这两个错误：
“NSURL”不能隐式转换为“URL”。 你的意思是使用“as”来明确转换吗？ – “NSURLRequest”不能隐式转换为“URLRequest”; 你的意思是用“as”来明确转换吗？
对于这种确切的情况，重新input你的行：
yourWebView.loadRequest(URLRequest(url: URL(string: "http://hardwirestudios.com")!))
…并将您的yourWebViewvariables重命名为一个，您实际使用。
在Swift 3.0中，几乎所有的NS都被丢弃，所以使用URL和URLRequest 。
WebView示例：
使用StoryBoard
ViewController.swift
import UIKit class ViewController: UIViewController, UIWebViewDelegate { @IBOutlet weak var webView: UIWebView! override func viewDidLoad() { super.viewDidLoad() webView.delegate = self if let url = URL(string: "http://apple.com") { let request = URLRequest(url: url) webView.loadRequest(request) } } }
Main.storyboard

结果
编程
import UIKit class ViewController: UIViewController, UIWebViewDelegate { var webView: UIWebView! override func viewDidLoad() { super.viewDidLoad() webView = UIWebView(frame: UIScreen.main.bounds) webView.delegate = self view.addSubview(webView) if let url = URL(string: "http://apple.com") { let request = URLRequest(url: url) webView.loadRequest(request) } } }

WKWebView示例
类WebView：UIViewController {
@IBOutlet var myWebView: UIWebView! var urlValue = "" override func viewDidLoad() { super.viewDidLoad() if let url = URL (string: urlValue){ let requestObj = URLRequest(url: url) _ = myWebView.loadRequest(requestObj) } }
}
