UIWebView用来在App内嵌入Web页面。如下代码装入Apple.com官方首页在App内。
import UIKit class Page: UIViewController{ var c : UIWebView! override func viewDidLoad() { super.viewDidLoad() c = UIWebView() c.frame = super.view.frame view.addSubview(c) c.frame.origin.y += 20 let url = URL(string:"http://apple.com") let ro = URLRequest(url:url!) c.loadRequest(ro) } } @UIApplicationMain class AppDelegate: UIResponder,UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication,didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { self.window = UIWindow(frame: UIScreen.main.bounds) self.window!.rootViewController = Page() self.window?.makeKeyAndVisible() return true } }
关键代码在于:
let url = URL(string:"http://apple.com") let ro = URLRequest(url:url!) c.loadRequest(ro)
构建URL对象和URLRequest请求对象,然后使用WebView的方法loadRequest发起请求,即可加载页面在WebView内。
