自定义 beamer 主题上的条件导航栏

我正在尝试创建自定义 beamer 模板。但是，我无法让导航栏在 中正确运行title page。

如图所示，导航栏应该在的位置，但导航栏变成了白色。如何才能让它完全不可见，让背景填满整个框架？并同时保留其他幻灯片上的导航栏。

在此处输入图片描述

正如你所看到的，我尝试了几件事：

  • 重写\titlepage命令以自动重新定义该headline部分，但是没有作用。奖励：我真的很想要这些解决方案，因为它允许我删除footlines或其他需要从中删除的调整title page。但是，我无法控制声明的宏的扩展。
  • headline在示例中调用之前手动重置。但是，我更喜欢自动解决方案。
  • \ifnum\thepage>1\relax在标题上添加条件 ( ) 以在第一页上表现不同，但它也会从第一张幻灯片中删除导航栏。这是我得到的最接近的解决方案。

代码如下：

您尝试设置的条件可以通过以下方式实现\insertframenumber：

\ifnum\insertframenumber>1\relax%
<code for the naviagtion bar>
\fi
