我在书籍环境中逐章制作练习，使用 tcolorbox 最新版本中的文档。在此版本中，标签是自动生成的（使用命令label={exercise@\thetcbcounter}）。我想像在以前的版本中一样，使用与命令相同的方式制作自己的标签，label={exe:#2}, 其中#2是我想要定义的标签的名称。我该怎么做？
我在文档中给出了一个包含数据的文件示例，并使用命令
The solution of the exercise \ref{[email protected]} is in the page \pageref{[email protected]}
所以我想分别通过标签[email protected]和来调用标签（在 .aux 文件中找到！）和。[email protected]exercise:mylabelsolution:mylabel

Compute the derivative of the following function:

The derivative is:
\begin{align*}
f’(x) &= \left( \sin((\sin x)^2) \right)’

使用 XeLatex 编译后得到：
答案1
以下代码为 添加了强制参数。此强制参数是将添加到和 的exercise标签。exercise:...solution:...
此标签的引入意味着更改tcolorbox中的label、after upper和record选项定义。以前的也已更改为。exercise#1#2
在solution框中没有新的参数，但是title和有所变化phantomlabel。

结果和辅助文件不会改变，只有aux文件中的内容会显示新的标签语法和值。
