当 beamer 模板中的标题为空时进行垂直对齐

当 beamer 模板中的标题为空时进行垂直对齐

我正在使用 Beamer 的自定义模板。除其他事项外，我完全重写了标题模板。但是，当我使用没有标题的框架时，垂直对齐方式与其他带标题的幻灯片不同。令人惊讶的是，无论标题是一行还是两行，它都能很好地工作……这很难解释，但在下面的例子中很容易看出。请注意第三张幻灯片中的错误垂直对齐方式。有趣的部分在第 68 行。知道这里发生了什么吗？

如果在第三帧中删除{}（表示标题为空），您将看到相同的垂直对齐问题。这对我来说意味着需要提供输入。在这种情况下，{}或\empty或\phantom{text}就可以解决问题。

\begin{frame}{{}} or \begin{frame}{\empty} or \begin{frame}{\phantom{a}}
