当我点击登录Facebook按钮时,它正在打开safari浏览器并立即关闭.控制台上出现错误.

App委托方法:

func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
    print("###### URL : ")
    print(url)
    print("###### App : ")
    print(app)
    print(options["UIApplicationOpenURLOptionsSourceApplicationKey"])
    return FBSDKApplicationDelegate.sharedInstance().application(app, openURL: url,  sourceApplication: options["UIApplicationOpenURLOptionsSourceApplicationKey"] as! String,
            annotation: nil)
}

我已经将iPhone 6 plus更新到iOS 9测试版,并试图执行Facebook登录,但每次使用Facebook登录表单呈现UIWebView.

我有Facebook sdk

FB_IOS_SDK_VERSION_STRING @"3.24.0"
FB_IOS_SDK_TARGET_PLATFORM_VERSION @"v2.2"

我正在使用以下方法来执行Facebook登录

    NSArray *permissions = @[@"email",@"user_birthday",@"public_profile"];


     FBSessionStateHandler completionHandler = ^(FBSession *session, FBSessionState status, NSError *error) {
         [self sessionStateChanged:session state:status error:error];
     };

     if ([FBSession activeSession].state == FBSessionStateCreatedTokenLoaded) {
     // we have a cached token, so open the session
         [[FBSession activeSession]openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
                                 fromViewController:nil
                                  completionHandler:completionHandler];
     } else {

     [self clearAllUserInfo];
    [[NSURLCache sharedURLCache] removeAllCachedResponses];

     // create a new facebook session
     FBSession *fbSession = [[FBSession alloc] initWithPermissions:permissions];
     [FBSession setActiveSession:fbSession];
     [fbSession openWithBehavior:FBSessionLoginBehaviorUseSystemAccountIfPresent
              fromViewController:nil
               completionHandler:completionHandler];
     }

我在plist文件下面进行了以下设置

    <key>LSApplicationQueriesSchemes</key>
    <array> …

我遇到了新的FBSDK问题.每当我尝试调用登录方法logInWithReadPermissions时,我收到以下错误消息:

错误:"canOpenUrl:url失败"fbauth2://"错误:"(null)"

我在dev.facebook上的ios9 tuto(https://developers.facebook.com/docs/ios/ios9)后面有我的配置.plist文件.所以,我得到了NSAppTransportSecurity字典和LSApplicationQueriesSchemes数组(上面有字符串"fbauth2")

你知道如何解决这个错误吗？

我通过Cocoapods安装了Facebook的Swift SDK:

pod 'FacebookCore', :git => "https://github.com/facebook/facebook-sdk-swift"
pod 'FacebookLogin', :git => "https://github.com/facebook/facebook-sdk-swift"

我已经按照Facebook的Swift SDK(https://developers.facebook.com/docs/swift/login)的登录说明进行操作,但无法使其正常工作.

在我的视图控制器中,我有以下内容:

@objc fileprivate func facebookSignIn() {
    let loginManager = LoginManager()
    print("LOGIN MANAGER: \(loginManager)")
    loginManager.logIn([ .publicProfile, .email ], viewController: self) { loginResult in
        print("LOGIN RESULT! \(loginResult)")
        switch loginResult {
        case .failed(let error):
            print("FACEBOOK LOGIN FAILED: \(error)")
        case .cancelled:
            print("User cancelled login.")
        case .success(let grantedPermissions, let declinedPermissions, let accessToken):
            print("Logged in!")
            print("GRANTED PERMISSIONS: \(grantedPermissions)")
            print("DECLINED PERMISSIONS: \(declinedPermissions)")
            print("ACCESS TOKEN \(accessToken)")
        }
    }
}

"登录经理:等等" 单击按钮打开时打印.我可以通过Facebook登录,然后网页视图变为空白,没有任何反应.该应用程序显示在我的Facebook应用程序中,因此已经进行了一些授权,但是如果我在Web视图中单击"完成"按钮,则回调的结果是.cancelled …
