  您可以使用ACAccountStore，如果用户没有社交框架，您也可以使用xamarin auth

  ACAccountStore accountStore = new ACAccountStore();
                      ACAccountType accountType = accountStore.FindAccountType(ACAccountType.Facebook);
  
                      AccountStoreOptions fbAccountStoreOptions = new AccountStoreOptions();
                      fbAccountStoreOptions.FacebookAppId = "333333";
                      fbAccountStoreOptions.SetPermissions(ACFacebookAudience.Everyone, new[] { "email", "user_birthday", "user_about_me","public_profile" });
  
                      Tuple<bool, NSError> requestResult = await accountStore.RequestAccessAsync(accountType, fbAccountStoreOptions);
  
                      if (requestResult.Item1)
                      {
                          ACAccount[] availableAccounts = accountStore.Accounts.Where(acco => acco.AccountType.Description == "Facebook").ToArray();
                          int fbAccountsCount = availableAccounts.Count();
  
                          if (fbAccountsCount < 1)
                          {
                              HandleFacebookAuthorizationUsingOAuthDialog();
                          }
                          else if (fbAccountsCount == 1)
                          {
                              HandleFacebookAuthorizationUsingACAccount(availableAccounts.First());
                          }}

                      fbAuthenticator.AllowCancel = true;
                      fbAuthenticator.Completed += FbAuthenticator_Completed;
                      fbAuthenticator.Error += FbAuthenticator_Error; ;
  
                      RootView.PresentViewController(fbAuthenticator.GetUI(), true, null);
                  }
                  catch (Exception ex)

                  params_.SetValueForKey(new NSString("id,name,birthday,gender"), new NSString("fields"));
  
                  SLRequest request = SLRequest.Create(SLServiceKind.Facebook, SLRequestMethod.Get, new NSUrl($"https://graph.facebook.com/me"), params_);

                  SLRequestResult response = await request.PerformRequestAsync();
  
                  NSHttpUrlResponse responseData = response.Arg2;
                  if (responseData.StatusCode == 200)
                  {
                      string jsonResponse = response.Arg1.ToString();
