Ios Facebook SDK:不正确的登录行为。“在会话状态下推送safari登录窗口”；开放式；

情境：
个人登录FBApp，但未登录系统FB帐户

我所做的：
我询问

readPermissions

和

publishPermissions

。之后，我发送个人身份（id、姓名、用户名、个人资料、图片和url）请求

行为：
一切正常，facebook ios sdk进入fb应用程序两次（每次请求-读取和发布），然后奇迹出现。 我请求提供个人身份，并查看facebook窗口，建议下载iPhone的fb应用程序（fb应用程序已经在上面了！），然后让我登录网站。我认为这是一个safari登录出现

代码：

/*login here*/
            if([_facebookSession state] == FBSessionStateCreated){
                [FBSession openActiveSessionWithReadPermissions:readPermissions allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                    if (error || status == FBSessionStateClosedLoginFailed){
                        [_facebookSession openWithBehavior:FBSessionLoginBehaviorWithNoFallbackToWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                            if (error || status == FBSessionStateClosedLoginFailed){
                                LoginFailedBlock(YES);
                            }

视图控制器：

self.loginview = [[FBLoginView alloc] init];
self.loginview.frame = CGRectMake(-500, -500, 0, 0);
[self.view addSubview:self.loginview];
self.loginview.delegate = self;
[loginview setReadPermissions:@[@"basic_info",@"email"]];
[loginview setDelegate:self];

 -(IBAction)loginWithFB:(id)sender{
    for(id object in self.loginview.subviews){
        if([[object class] isSubclassOfClass:[UIButton class]]){
            UIButton* button = (UIButton*)object;
            [button sendActionsForControlEvents:UIControlEventTouchUpInside];
        }
    }
}

在appdelegate中：

- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation {

    // Call FBAppCall's handleOpenURL:sourceApplication to handle Facebook app responses
    BOOL wasHandled = [FBAppCall handleOpenURL:url sourceApplication:sourceApplication];

    // You can add your app-specific url handling code here if needed

    return wasHandled;
}

然后，请在developer.facebook.com中注册您的应用程序，并使用您的bundle id。最后，您将获得一个id，并在plist文件中进行配置
