Beamer 添加对页脚的引用

Question

页面底部应如下所示。

但有些页面可以有多个引用。

正如您所看到的，参考字体大小和帧号字体大小并不相同，这非常好。

最后的参考应该与帧号对齐，因此两个底部应该在同一行。

有些框架没有参考。但在每个框架上保留四个“位置”作为参考。因此，在每个框架上始终保留四个“位置”空闲。

我根本不知道怎样才能实现这一目标。

由于您幸运地没有使用帧编号的脚注，因此您可以使用\footnotes \footcite（来自 biblatex）或类似工具来添加您的参考资料。

这是一个带有未编号脚注的简短示例：

\usetheme{Copenhagen}
\usecolortheme{beaver}

\setbeamertemplate{navigation symbols}{}

\setbeamertemplate{footline}{}
%insert frame numbering
\addtobeamertemplate{navigation symbols}{}{
    \usebeamerfont{footline}
    \usebeamercolor[fg]{footline}
    \hspace{1em}
    \large \insertframenumber/\inserttotalframenumber
}
%no frame number on the title frame
\AtBeginSection[]{
