我正在处理一份 beamer 文档，其中有很多示例。我编写了几个宏，这些宏会自动添加带有“示例 #”的框架标题，并将这些框架添加到目录中以方便导航。但是，这些“示例 #”没有超链接到目录中的各自框架，但如果我在文档的其他地方引用它们，它们就会正确链接。这是我的 MWE 代码：
\documentclass[10pt,
hyperref={
%bookmarks=true,
linktocpage=true,
linktoc=all,
implicit=true,
%hypertexnames=false,
%debug
final=true
%
},
handout
]{beamer}
\usepackage[spanish.noindentfirst,shorthands=off]{babel}
\accentedoperators
\decimalpoint
\usepackage[utf8]{inputenc}
\useoutertheme{infolines}
\usecolortheme{spruce}
\setbeamertemplate{headline}{
\leavevmode\hbox{
\begin{beamercolorbox}
[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,right]{section in head/foot}%
\usebeamerfont{section in head/foot}\inserttitle: ~\insertsubtitle\hspace*{2ex}
\end{beamercolorbox}%
\begin{beamercolorbox}
[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,left]{subsection in head/foot}%
\usebeamerfont{subsection in head/foot}\hspace*{2ex}\insertsectionhead
\end{beamercolorbox}}%
\vskip0pt}
\setbeamertemplate{footline}{}
\mode<handout>{\setbeamertemplate{footline}[frame number]}
\setbeamertemplate{blocks}[rounded]
\setbeamertemplate{itemize item}{\color{mygreen}$\blacktriangleright$}
\setbeamertemplate{enumerate item}[circle]
\setbeamercolor{local structure}{fg=mygreen}
\setbeamertemplate{theorems}[numbered]
\def\subsubsectionname{Example}
\newcounter{ejc}
\newcommand{\ExFr}[1][\empty]{
\refstepcounter{ejc}
\phantomsection
\label{#1}
\frametitle{Example ~\theejc}
\addcontentsline{toc}{subsection}{\quad Example ~\theejc\\}}
\newcommand{\ExFrC}{
\frametitle{Example ~\theejc}}
\resetcounteronoverlays{ejc}
\usepackage[most]{tcolorbox}
\colorlet{mygreen}{green!16!gray}
\title{A}
\subtitle{B}
\date{}
\setcounter{ejc}{16}
\begin{document}
\frame[plain]{\titlepage}
\section*{Contents}
\begin{frame}<beamer:0>%On handout only
\begin{columns}[t]
\begin{column}{.5\textwidth}\tableofcontents[sections={2-}]\end{column}
\begin{column}{.5\textwidth}
%\tableofcontents[sections={2-4}]
\end{column}
\end{columns}
\end{frame}
\section{Math}
\begin{frame}
\ExFr[arbpar]%
$1+1=2$
\end{frame}
\begin{frame}
\ExFrC
Also $1+2=3$.
\end{frame}
\begin{frame}
Wow.
\end{frame}
\begin{frame}
\ExFr
Remember example \ref{arbpar}.
\end{frame}
\end{document}
所以最后\ref提供了指向相应框架的可点击超链接，但我无法让 toc 执行此操作。如您所见，我一直在尝试各种选项，但似乎都不起作用。任何帮助都非常感谢！

你可以在将练习添加到目录中时添加链接，如下所示：
\documentclass[10pt,handout]{beamer}
\usepackage[spanish.noindentfirst,shorthands=off]{babel}
\accentedoperators
\decimalpoint
\usepackage[utf8]{inputenc}
\useoutertheme{infolines}
\usecolortheme{spruce}
\setbeamertemplate{headline}{
\leavevmode\hbox{
\begin{beamercolorbox}
[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,right]{section in head/foot}%
\usebeamerfont{section in head/foot}\inserttitle: ~\insertsubtitle\hspace*{2ex}
\end{beamercolorbox}%
\begin{beamercolorbox}
[wd=.5\paperwidth,ht=2.65ex,dp=1.5ex,left]{subsection in head/foot}%
\usebeamerfont{subsection in head/foot}\hspace*{2ex}\insertsectionhead
\end{beamercolorbox}}%
\vskip0pt}
\setbeamertemplate{footline}{}
\mode<handout>{\setbeamertemplate{footline}[frame number]}
\setbeamertemplate{blocks}[rounded]
\setbeamertemplate{itemize item}{\color{mygreen}$\blacktriangleright$}
\setbeamertemplate{enumerate item}[circle]
\setbeamercolor{local structure}{fg=mygreen}
\setbeamertemplate{theorems}[numbered]
\def\subsubsectionname{Example}
\newcounter{ejc}
\newcommand{\ExFr}[1][\empty]{
\refstepcounter{ejc}
\phantomsection
\label{exercise-\theejc}
\label{#1}
\addtocontents{toc}{\quad\hyperlink{exercise-\theejc}{Example ~\theejc}\\}
