使用Swift 3的FBlogin不会返回任何值，并且在成功login后不会返回用户到应用程序

我正在使用iOS 10 Swift 3来集成FB Login 。 我遵循了Facebook文档中的所有步骤。 现在的问题是，成功login后，它不会返回任何值，也不会让用户回到应用程序。

注意：在Swift 2完全一样。

Answer 1

嗨，我提出这个问题的Facebook开发人员的支持，问题是，我没有实现iOS10的正确的委托方法。 你可以在这里find正确的委托实现

 import UIKit import CoreData @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? public func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool { // Override point for customization after application launch. return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions) } public func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { return FBSDKApplicationDelegate.sharedInstance().application( app, open: url as URL!, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation] ) } public func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool { return FBSDKApplicationDelegate.sharedInstance().application( application, open: url as URL!, sourceApplication: sourceApplication, annotation: annotation) } }

对于我来说，“FBSDKApplicationDelegate”不适用于最新的Facebook Swift SDK版本v0.2.0

你可以在这里find我的v0.2.2的实现： https ：//gist.github.com/mbecker/bdbd28cd11394085c01cf442aaa42c72

Answer 4

Evn：iOS 10，XCode 8.3.2，Swift 3，facebook-sdk-swift-0.2.0testing和工作。

由于上面的答案被指定为不推荐的代码，所以我改变了语法。

Answer 5

我经历了与Facebook和Twitter整合相同的问题。我已经解决了如下。

 func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool { let appname:String = options.first?.value as! String print(appname) if appname == "com.facebook.Facebook" { return FBSDKApplicationDelegate.sharedInstance().application( app, open: url as URL!, sourceApplication: options[UIApplicationOpenURLOptionsKey.sourceApplication] as! String, annotation: options[UIApplicationOpenURLOptionsKey.annotation] ) } return Twitter.sharedInstance().application(app, open: url, options: options) }
