【中文标题】Swift SFSafariViewController 目前显示空白页【英文标题】：Swift SFSafariViewController present show blank page 【发布时间】：2020-05-07 21:53:42 【问题描述】：EDIT2 这是一个包含 2 个类的 MWC，其中只有 SFSafariViewController 用于打开嵌入的 url。我在屏幕上看到的是一个空白页 文件也在这里https://github.com/camillegallet/testSwiftSafariEmbeded
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:.
视图控制器
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)")
我在库中有这个旧函数
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
我用这些行调用这个函数
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页面，我在网络上没有找到正确的工作解决方案 我也测试过 让 url=URL(string: "http://www.google.com")
即使这样也行不通
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

【参考方案1】：这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
