我無法在ios中獲取Facebook用戶信息

我是新手，我使用下面的代碼進行手機編程，我正在從Facebook獲取信息。但問題是，如果點擊按鈕，它會去Facebook應用程序問Facebook的用戶名和密碼後，它顯示相同的view.But在這裏我提取用戶信息，但IAM無法獲取information.Its後開放Facebook頁面回到相同的頁面。再次點擊也重複同樣的事情。可以任何一個告訴如何解決這個問題。我無法在ios中獲取Facebook用戶信息

FBLoginView *fbLoginview = [[FBLoginView alloc] initWithPermissions:[NSArray arrayWithObject:@"publish_actions"]]; 

    //loginview.frame = CGRectOffset(loginview.frame, 2, 2); 
    // loginview.frame = loginWithFbButton.frame; 

    fbLoginview.frame = CGRectMake(30, 10, 200, 30); 
    for (id obj in fbLoginview.subviews) 
    { 
     if ([obj isKindOfClass:[UIButton class]]) 
     { 
      loginWithFbButton = obj; 
      loginWithFbButton.frame = CGRectMake(0, 0, 200, 30); 

      // UIImage *loginImage = [UIImage imageNamed:@"YourImg.png"]; 
      [loginWithFbButton setBackgroundColor:[UIColor colorWithRed:69.0/255.0 green:115.0/255.0 blue:185.0/255.0 alpha:1]];

      CAGradientLayer *gradient1 = [CAGradientLayer layer]; 
      gradient1.frame = loginWithFbButton.bounds;

     } 

     if ([obj isKindOfClass:[UILabel class]]) 
     { 
      UILabel * loginLabel = obj; 
      loginLabel.text = nil; 
      loginLabel.textAlignment = NSTextAlignmentCenter; 
      loginLabel.frame = CGRectMake(0, 0, 271, 26); 
     } 
    } 

    // fbLoginview.delegate = self; 

    [loginTempview3 addSubview:fbLoginview];

Facebook的代碼在哪裏？ –

對於獲取用戶信息使用Facebook圖形API

請看看這個https://developers.facebook.com/docs/ios/ios-sdk-tutorial/

請確保您有實現Facebook的委託方法，

fbLoginview.delegate = self;

而實現此方法獲取用戶信息

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView 
          user:(id<FBGraphUser>)user { 
    // here we use helper properties of FBGraphUser to dot-through to first_name and 
    // id properties of the json response from the server; alternatively we could use 


    NSLog(@"user :%@",user); 
}

感謝您提供重播我將盡力.. –

也許這不是你的問題！沒有人能夠在Facebook上發佈，評論或發表評論。這可能是原因...也許它在一個小時內運行良好！
