如何发出命令来显示自定义标题页？

我听从了这个问题的建议\makeatletter 和 \makeatother 起什么作用？尝试制作一个显示自定义标题页的自定义命令，但它不起作用。

./article.tex:17: You can't use `\spacefactor' in vertical mode.\@ ->\spacefactor
                  \@m
l.17 \makecustomtitle

Sorry, but I'm not programmed to handle this case;
I'll just pretend that you didn't ask for it.
If you're in the wrong mode, you might be able to
return to the right one by typing `I}' or `I$' or `I\par'.
./article.tex:17: Missing $ inserted.<inserted text>
                $
l.17 \makecustomtitle

I've inserted a begin-math/end-math symbol since I think
you left one out. Proceed, with fingers crossed.
./example.tex:17: You can't use `\spacefactor' in math mode.\@ ->\spacefactor
                  \@m
l.17 \makecustomtitle

l.17 \makecustomtitle

以下是简化的代码：

\documentclass[12pt]{article}

\newcommand{\makecustomtitle}{
\begin{titlepage}
  \makeatletter

  \@title by \@author

  \makeatother
\end{titlepage}
}

\begin{document}
\title{Please, be my title}
\author{Andres Riofrio}

\makecustomtitle

Take on me.

\end{document}

您需要将\makeatletter和\makeatother移到 之外\newcommand。

\makeatletter
\newcommand{\makecustomtitle}{%
  \begin{titlepage}
    \@title by \@author
  \end{titlepage}
}
\makeatother

区别在于，在上述设置中，类别代码在定义时发生更改；而在您的设置中，它们试图在使用时发生更改。
