我正在使用 Swift 3.0 集成 Facebook SDK 4.15.1。

我已经按照链接中提到的所有步骤进行操作 Getting started with iOS ，我可以使用 Safari 浏览器登录 Facebook 并进行授权，但之后控件不会返回到我的应用程序，并显示一个空白页面。但是当我按下完成按钮时，委托(delegate)方法 didCompleteWith result: 被调用并出现错误 OAuthException。此外，我的应用程序中从未调用过 OpenURL 方法。我还彻底验证了我的属性列表文件和应用程序 ID，包标识符或应用程序 ID 没有错误。

< ios="" 9.0="">

感谢任何帮助。

下面是我在 Swift 3.0 中登录和获取访问 token 的代码，

AppDelegate.swift
    import UIKit
    import CoreData
    import FBSDKCoreKit
    import FBSDKLoginKit
    import FBSDKShareKit

    @UIApplicationMain
    class AppDelegate: UIResponder, UIApplicationDelegate, GIDSignInDelegate  {

   var window: UIWindow? 
   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {   
            FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)   
            return true
        }

    func application(application: UIApplication,
                     openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
        return FBSDKApplicationDelegate.sharedInstance().application(application, open: url as URL!, sourceApplication: sourceApplication, annotation: annotation)    
    }

    func applicationDidBecomeActive(_ application: UIApplication) {
        FBSDKAppEvents.activateApp()
    }

ViewController.swift

import UIKit
import FBSDKLoginKit
import FBSDKCoreKit

class ViewController: UIViewController, GIDSignInUIDelegate, FBSDKLoginButtonDelegate  {
    public func loginButtonDidLogOut(_ loginButton: FBSDKLoginButton!) {
     }

        let loginView : FBSDKLoginButton = FBSDKLoginButton()
        self.view.addSubview(loginView)
        loginView.center = self.view.center
        loginView.readPermissions = ["public_profile", "email", "user_friends"]
        loginView.delegate = self    
}
func loginButton(_ loginButton: FBSDKLoginButton!, didCompleteWith result: FBSDKLoginManagerLoginResult!, error: Error!) {
    if error == nil {
        print("Success")

        let graphRequest : FBSDKGraphRequest = FBSDKGraphRequest(graphPath: "me", parameters: ["fields":"id,interested_in,gender,birthday,email,age_range,name,picture.width(480).height(480)"])
        graphRequest.start(completionHandler: { (connection, result, error) -> Void in

            if ((error) != nil)
            {
                print("Error: \(error)")
            }
            else
            {
                print("fetched user: \(result)")
            }
        })
    }else{
        print("Failure")
    }
}

最佳答案

我已通过在属性列表中添加以下传输安全 key 解决了这个问题。

<key>NSAppTransportSecurity</key>
<dict>
    <key>NSExceptionDomains</key>
    <dict>
        <key>facebook.com</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
        <key>fbcdn.net</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
        <key>akamaihd.net</key>
        <dict>
            <key>NSIncludesSubdomains</key>
            <true/>
            <key>NSExceptionRequiresForwardSecrecy</key>
            <false/>
        </dict>
    </dict>
</dict>
