我在我的应用程序的用户的Facebook墙上发布了一些故事。它的工作正常,但我想知道是否有其他用户想在我的应用程序与其他Facebook帐户登录他怎么能做到这一点。我的意思是我如何注销现有的用户并允许其他用户登录。我在AppDelegate的代码是:如何在您的应用的Facebook上登录其他用户?

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  
     [self.window addSubview:navigationController.view]; 
     [self.window makeKeyAndVisible]; 
     facebook = [[Facebook alloc] initWithAppId:@"app_id"]; 

     NSArray* permissions = [[NSArray arrayWithObjects: 
         @"publish_stream", nil] retain]; 

     [facebook authorize:permissions delegate:self]; 
    return YES; 
} 

    - (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url { 

     return [facebook handleOpenURL:url]; 
    } 

和我DetailViewController代码:

AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate]; 

    SBJSON *jsonWriter = [[SBJSON new] autorelease]; 
    NSDictionary* attachment = [NSDictionary dictionaryWithObjectsAndKeys: 
         [sTitle stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""], @"name", 
         [sSummary stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""], @"description", 
         [sLink stringByReplacingOccurrencesOfString:@"\"" withString:@"\\\""], @"href", nil]; 
     NSString *attachmentStr = [jsonWriter stringWithObject:attachment]; 
     NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: 
          @"XXX", @"api_key", 
          @"Share on Facebook", @"user_message_prompt", 
          attachmentStr, @"attachment", 
          nil]; 

    [appDelegate.facebook dialog:@"stream.publish" andParams:params andDelegate:self]; 

一旦应用程序被安装,它要求为Facebook用户名和密码。然后它仅向该用户发布故事。如果我想在我的应用程序中更改用户,那该怎么办?我应该在哪里写

[facebook logout:self];
