Ios 未使用Facebook SDK在Facebook中对用户进行签名

我正在尝试从服务器检索数据。当json请求成功时，服务器应该返回用户的基本信息

我的问题是，当我将此代码删除到.plist文件时：

<key>CFBundleURLTypes</key>
<array>
<dict>
    <key>CFBundleURLSchemes</key>
    <array>
        <string>fb***</string>
    </array>
</dict>
</array>

这将显示要弹出的登录视图：

以及我需要正确获取的所有数据。但我想要的是在浏览器中登录，然后返回应用程序。。因此，我在.plist文件中包含了上面的代码

以下是我获取值的代码：

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user {
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];

if ([[NSUserDefaults standardUserDefaults] valueForKey:FB_DISPLAY_NAME_TEXT] !=nil) {}else{
    NSLog(@"@@wew: %@", [[NSUserDefaults standardUserDefaults] valueForKey:FB_DISPLAY_NAME_TEXT]);
    [webService getDataFromURL:[NSString stringWithFormat:@"%@%@", ROOT_SERVER_URL, FB_URL_LOGIN]];
}

---

这段代码在登录弹出时获取我需要的数据。我需要用户先登录，所以我把请求放在那里。我的代码中有问题吗？

首先将openurl代码放在appdelegate.m文件中

然后使用以下代码登录facebook：

 NSArray *permissions = [NSArray arrayWithObjects:@"email", @"public_profile", @"user_friends",nil];

                              if (!error) {

                                  hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
                                  hud.labelText = @"Loading...";
                                  hud.dimBackground = NO;

谢谢你。很抱歉反应太晚，我很难修复我的应用程序。
