我正在尝试使用 opaline 样式在章节标题中添加引文（是的，我知道有些人认为这是一个坏主意，但我们现在先不讨论这个问题）。如果我输入
\section{Section Heading \citep{...}}
一切都很好。但是如果我把
\section{Section Heading \textcolor{...}{\cite{...}}}
然后我收到一个错误：
...
Argument of \
@gobble has an extra }.
<inserted text>
\par
l.1 ... \textcolor{Magenta!50}{\citep{Li:2013uq}}}
我也试过
\section{Section Heading} \section{Section Heading \textcolor{...}{\cite{...}}
在这种情况下，它会将引用移至下一页的开头。
有什么办法可以做到我想做的事吗，还是徒劳无功？
更新：根据要求，我正在添加 MWE。

您需要\protect以下命令\textcolor：
\documentclass[table,xcolor=pdftex,dvipsnames]{beamer}
\usetheme{Madrid}
\usecolortheme{whale}
\usepackage[square]{natbib}
\begin{document}
\title{Presentation Title}
\author{Author}
\institute{Institution}
\date{}
\frame{\titlepage}
\section*{Outline}
\begin{frame}
\frametitle{Outline}
\tableofcontents
\end{frame}
\section{Section 1}
\section{Section 2 \citep{ov11}} %This works
\frame{
\frametitle{A Sample Frame}}
\section{Section 3 \protect\textcolor{Magenta}{\citep{ov11}}} %This gives error
\bibliographystyle{apalike-url}
\begin{thebibliography}{}
\bibitem[{\"O}zsu and Valduriez, 2011]{ov11}
{\"O}zsu, M.~T. and Valduriez, P. (2011).
\newblock {\em Principles of Distributed Database Systems}.
\newblock Springer, 3rd edition.
