删除第一张和最后一张幻灯片中的小框架

Question

基本上，我需要删除第一张幻灯片和最后一张幻灯片中的小框架（各部分所在的位置），这可能吗？这是我的 MWE：

\documentclass{beamer}
\usetheme{Warsaw}
    \setbeamertemplate{footline}[page number]
    \setbeamercovered{invisible}
    \setbeamertemplate{navigation symbols}{}
\usecolortheme{dolphin}
\useoutertheme[footline=empty,subsection=false]{miniframes}

\usepackage{graphicx}

\title{The Simpsons}
\author{Krusty the Clown\\(this first slide must not have the miniframes!!)}
\date{\today}

\begin{document}

% Main slide
\begin{frame}
   \titlepage
\end{frame}

\section{Second slide, yeah!!}
\begin{frame}
    This slide must have the miniframe, the first one must not!
\end{frame}

\section{Third slide, yeah!!}
\begin{frame}
    This slide must also have the miniframe (and so forth), the first one must not!
\end{frame}

% Last slide
\begin{frame}
    Thank you for your attention\\(this slide must not have the miniframes!!)
\end{frame}

\end{document}

谢谢您的提示，

找到了，只需在每个幻灯片/框架环境中使用 [plain] 即可：

...
% Main slide
\begin{frame}[plain]
   \titlepage
\end{frame}
...
...
% Last slide
\begin{frame}[plain]
    Thank you for your attention\\(this slide must not have the miniframes!!)
\end{frame}
