ios - 如何从我的 native ios 应用程序中登录 Twitter 帐户

Question

我正在使用 Fabric SDK 登录 Twitter 帐户，因为我登录了，所以在我的 viewDidLoad 方法中执行以下代码

- (void)viewDidLoad
{
       [super viewDidLoad];

    TWTRLogInButton *loginButton = [TWTRLogInButton buttonWithLogInCompletion:^(TWTRSession *session,NSError *error){

        if (session) {
//            mysession =session;
            NSLog(@"signed in as %@", [session userName]);
        } else {
            NSLog(@"error: %@", error );
        }

    }];
    loginButton.center = self.view.center;
    [self.view addSubview:loginButton]; 
}


//and i use one UIButton for logOut ,And code for logout is as like

(IBAction)tweet:(id)sender
{
  [[Twitter sharedInstance] logOut];
}

但是这段代码对我不起作用，请建议我一个正确的方法

这是 Foundation 框架中 NSCookie 的问题，我借助以下代码解决了这个问题

NSURL *url = [NSURL URLWithString:@"https://api.twitter.com"];

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookiesForURL:url];
for (NSHTTPCookie *cookie in cookies)
{
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
}
