Facebook iOS SDK 3.0 - 会话未打开

Question

我正在使用最新的Facebook iOS SDK 3.0

我需要在登录过程中提供帮助:

首先,我在AppDelegate.h以下位置声明此属性:

@property (nonatomic, strong) FBSession *session;

在ViewController类中我得到这个在代码中使用它,如下所示:

AppDelegate *delegate = [[UIApplication sharedApplication]delegate];
[delegate.session someproperty];

我在ViewController中也有这个方法从以下方法调用viewDidLoad:

-(void)login
{
    AppDelegate *delegate = [[UIApplication sharedApplication]delegate];
    [delegate.session accessToken];
    NSLog(@"%d",delegate.session.isOpen);
    if (!delegate.session.isOpen)
    {
        delegate.session = [[FBSession alloc] init];
        if (delegate.session.state == FBSessionStateCreatedTokenLoaded)
        {
            [delegate.session openWithCompletionHandler:^(FBSession *session,
                                                      FBSessionState status,
                                                      NSError *error) 
            {
              NSLog(@"%d", delegate.session.isOpen); // First Line //////////////////
            }];
        }
        NSLog(@"%@", delegate.session.description);   // Second Line //////////////////
    }
 }

Facebook应用程序获得授权后,第一个NSLog打印零,第二个NSLog表明session状态FBSessionStateCreated不是FBSessionStateOpen？

这是第二个的输出NSLog:

2012-08-16 18:37:24.327 Facebook3[2418:f803] <FBSession: 0x6890ff0, state:    FBSessionStateCreated, loginHandler: 0x0, appID: 193716877424306, urlSchemeSuffix: , tokenCachingStrategy:<FBSessionTokenCachingStrategy: 0x6890f20>, expirationDate: (null), refreshDate: (null), attemptedRefreshDate: 0001-12-30 00:00:00 +0000, permissions:()>

我在这里失踪了什么.

注意:在https://developers.facebook.com的应用程序设置中,我将应用程序配置为:1-配置为iOS SSO:已启用2- iOS本机深层链接:已启用3- iOS捆绑ID:com.mycompany.appname

我将这个框架用于我的项目.它工作正常.这是我的相关代码

   -(IBAction)logIn:(id)sender;
{
    AppDelegate *appdelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    if (!FBSession.activeSession.isOpen) {
        [appdelegate sessionOpener];
    }
    else {
        [self loginHelp];
    }

而我的sessionOpener函数是;

    -(void) sessionOpener
{

    [FBSession sessionOpenWithPermissions:nil
                        completionHandler:^(FBSession *session,
                                            FBSessionState status,
                                            NSError *error) {
                            // session might now be open.
                            if (!error) {
                                [self.viewController loginHelp];
                            }
                        }];

     NSLog(@"%d", FBSession.activeSession.isOpen);
    NSLog(@"%@", FBSession.activeSession.description );
}

这个对我有用.可能对你有所帮助.

我的控制台打印是:
