EDIT2这里是一个MWC，包含2个类，只有SFSafariViewController用于打开一个嵌入的url。我在屏幕上得到的是一个空白的页面文件也在这里 https:/github.comcamillegallettestSwiftSafariEmbed。
AppDelegate
import UIKit
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
func applicationWillResignActive(_ application: UIApplication) {
// Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
// Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game.
}
func applicationDidEnterBackground(_ application: UIApplication) {
// Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
// If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}
func applicationWillEnterForeground(_ application: UIApplication) {
// Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}
func applicationDidBecomeActive(_ application: UIApplication) {
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
func applicationWillTerminate(_ application: UIApplication) {
// Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

查看控制器
import UIKit
import WebKit
import SafariServices
class ViewController: UIViewController {
@IBOutlet weak var KronosWebsite: WKWebView!
override func loadView() {
KronosWebsite = WKWebView()
self.view = KronosWebsite
}
override func viewDidLoad() {
super.viewDidLoad()
openGoogle()
}
func openGoogle(){
let url2=URL(string: "http://www.google.com")
let web = SFSafariViewController(url: url2!)
let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
if var topController = keyWindow?.rootViewController {
while let presentedViewController = topController.presentedViewController {
topController = presentedViewController
}
do{
topController.present(web, animated: true, completion: nil)
}catch let error {
DispatchQueue.main.async {
print("ERROR \(error)")
}
}
}
}
}
我在一个库里有一个老函数
public func authorizeSafariEmbedded(from controller: UIViewController, at url: URL) throws -> SFSafariViewController {
safariViewDelegate = OAuth2SFViewControllerDelegate(authorizer: self)
let web = SFSafariViewController(url: url)
web.title = oauth2.authConfig.ui.title
web.delegate = safariViewDelegate as! OAuth2SFViewControllerDelegate
if #available(iOS 10.0, *), let barTint = oauth2.authConfig.ui.barTintColor {
web.preferredBarTintColor = barTint
}
if #available(iOS 10.0, *), let tint = oauth2.authConfig.ui.controlTintColor {
web.preferredControlTintColor = tint
}
web.modalPresentationStyle = oauth2.authConfig.ui.modalPresentationStyle
willPresent(viewController: web, in: nil)
controller.present(web, animated: true, completion: nil)
return web
}
我调用这个函数的时候有这样几行字
let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first
if var topController = keyWindow?.rootViewController {
while let presentedViewController = topController.presentedViewController {
topController = presentedViewController
}
do{
let web = try authorizer.authorizeSafariEmbedded(from: topController,at: url!)
}catch let error {
DispatchQueue.main.async {
print("ERROR \(error)")
}
}
}
但是我一直有一个空白的页面，我在网上没有找到一个正确的工作方案我也测试过用let url=URL(string: "http:/www.google.com")
这也不行
public func authorizeSafariEmbedded(from controller: UIViewController, at url: URL) throws -> SFSafariViewController {
let web = SFSafariViewController(url: url)
web.title = oauth2.authConfig.ui.title
controller.present(web, animated: true, completion: nil)
return web
}

下面是我为使它工作所做的工作。
import UIKit
import WebKit
import SafariServices
class ViewController: UIViewController {
var safariVC = SFSafariViewController(url: URL(string: "https://apple.com")!)
@IBOutlet weak var KronosWebsite: WKWebView!
override func loadView() {
KronosWebsite = WKWebView()
self.view = KronosWebsite
}
func addViewControllerAsChildViewController() {
addChild(safariVC)
self.view.addSubview(safariVC.view)
safariVC.didMove(toParent: self)
self.setUpConstraints()
}
override func viewDidLoad() {
super.viewDidLoad()
addViewControllerAsChildViewController()
}
func setUpConstraints() {
self.safariVC.view.translatesAutoresizingMaskIntoConstraints = false
self.safariVC.view.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor, constant: 30).isActive = true
self.safariVC.view.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor, constant: -30).isActive = true
self.safariVC.view.leadingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.leadingAnchor, constant: 30).isActive = true
self.safariVC.view.trailingAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.trailingAnchor, constant: -30).isActive = true
}
}
