How to hide footer (or footline) in a particular slide in Beamer?

I am preparing a presentation in Beamer. I have done a开发者_运维知识库 few customizations to the template I am using. Now I want to hide the footline on the title slide. I also want to hide it on a few other slides. How do I achieve that?

Thanks!

If you want a purely plain slide, you give the [plain] option to the frame.

The plain option is the perfect solution if you want to hide both the headline and the footline. If there are slides for which you only want to hide the footline - but keep the headline - you can temporarily redefine it like in the following example:

\documentclass{beamer}

\setbeamertemplate{footline}[frame number]


\begin{document}

\begin{frame}
normal frame
\end{frame}

\begingroup
\setbeamertemplate{footline}{}
\begin{frame}
without footline
\end{frame}
\endgroup

\begin{frame}
normal frame
\end{frame}

\end{document}
