使用Swift 3進行FB登錄沒有返回任何值，並且在成功登錄後不會返回用戶

Question

我正在使用iOS 10Swift 3來集成FB Login。我遵循了Facebook文檔中的所有步驟。現在的問題是，成功登錄後，它不會返回任何值，也不會讓用戶回到應用程序。

注意：在Swift 2中完全相同。

Answer 1

嗨我提出這個問題到facebook開發人員的支持，問題是我沒有實現iOS10的正確委託方法。你可以找到正確的委託執行here

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) 
} 
}

對我來說，「FBSDKApplicationDelegate」沒有最新的Facebook斯威夫特SDK版本v0.2.0工作

你可以在這裏找到我的v0.2.2實施：https://gist.github.com/mbecker/bdbd28cd11394085c01cf442aaa42c72

不要忘記設置鑰匙扣共享 項目目標 - >性能 - >鑰匙扣共享 - >切換開關ON

你可以按照這個 http://ashishkakkad.com/2015/05/facebook-login-swift-language-ios/

Answer 4

EVN：iOS的10時，Xcode 8.3.2，斯威夫特3，Facebook的SDK-迅速-0.2.0 和測試工作。

由於上面的答案被指定爲不建議使用的代碼，所以我更改了語法。

Answer 5

我已經經歷了Facebook和Twitter integration.I同樣的問題如下解決了它。

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) 
}
