如何引用盒子定理？

Question

我试图引用定理数

\documentclass{article} 
\usepackage{amsthm}
\usepackage[bookmarks=true]{hyperref}
\usepackage[many]{tcolorbox}
\newtcbtheorem[number within=section]{Theorem}{Theorem}{
  enhanced,breakable,
  sharp corners,
  attach boxed title to top left={
    yshifttext=-1mm
  },
  colback=white,
  colframe=blue!75!black,
  fonttitle=\bfseries,
  boxed title style={
    sharp corners,
    size=small,
    colback=blue!75!black,
    colframe=blue!75!black
  }
}{thm}

\begin{document}
\section{Section 1}

\subsection{Subsection 1}
\begin{Theorem}{First}{}\label{first}
test
\end{Theorem}

Here we refer Theorem \ref{first}
\begin{Theorem}{Second}{}\label{second}
test
\end{Theorem}
Here we refer Theorem \ref{second}
\end{document}

但我好像引用的是小节编号而不是定理编号。我该如何解决这个问题？

Answer 1

定义的正确语法是

\newtcbtheorem[init options]{Theorem box name}{Theorem title}{options}{prefix for label}

正确的用法是

\begin{foo}{title}{labelname}

当定理具有框名 foo 时。稍后，使用\ref{thm:labelname}，假设前缀为thm。:会自动添加，但可以使用选项 进行更改label separator。

话虽如此，标签是从tcbtheorem定理的第二个参数添加的。外面将使用指向 OP 中第一个小节的\label{foo}旧引用。\@currentlabel
