FBLoginView没有收到用户的电子邮件

Question

当我这样做时：

- (void) viewDidLoad {
  [_fbLoginView setReadPermissions:@[@"public_profile", @"email"]];
  [_fbLoginView setDelegate:self];
}

- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView
                            user:(id<FBGraphUser>)user {
  self.profilePictureView.profileID = user.id;
  self.nameLabel.text = user.name;
}

我得到：

(lldb) po user
{
    "first_name" = Name;
    gender = female;
    id = 1459547723244130;
    "last_name" = Surname;
    link = "https://www.facebook.com/app_scoped_user_id/1459547723244130/";
    locale = "en_US";
    name = "Name Surname";
    timezone = 1;
    "updated_time" = "2014-06-30T08:07:59+0000";
    verified = 1;
}

即使我收到通知，申请人需要我的电子邮件地址。
