tikz-uml 在序列图中删除对象

我希望有人能帮助我。我用 tikz-uml 创建了一个对象。我想删除它，但我不知道该怎么做。我想要一个同步箭头，就像 create 上的箭头一样，然后在对象的生命线上有一个“x”。此示例代码应以 b 生命线上的“x”上的 delete 结尾。

\documentclass[a4paper, fontsize=12pt]{scrartcl}
\usepackage{ifthen}
\usepackage{xstring}
\usepackage{pgfkeys}
\usepackage{pgfopts}
\usepackage{tikz-uml}

\begin{document}
\begin{tikzpicture}
\begin{umlseqdiag}
\umlobject[class=A]{a}
\umlcreatecall [ class=B] {a}{b}
\begin{umlcall}
[op={function()},dt=6, type=synchron, return={return}]{a}{b}
\end{umlcall}
\begin{umlcall}
[op={delete}, dt=4, type=synchron, ]{a}{b}
\end{umlcall}
\end{umlseqdiag}
\end{tikzpicture}
\end{document}

希望对你有帮助。将修改后的代码粘贴到文件“tikz-uml.sty”的最后一行中。

            }
    \end{pgfonlayer}
}

现在您可以按如下方式调用所需的解决方案：

\begin{umlcallKill}[dt=3,op={functionName()}]{instanceNameSrc}{instanceNameDes}
\end{umlcallKill}

重要的是，您只输入“dt=”和“op={}”，但必须指定它们。自调用不起作用。然后您将得到以下内容：

示例代码：

\documentclass[border=1]{standalone}
\usepackage[english]{babel}
\usepackage{tikz-uml}
\begin{document}
    \begin{tikzpicture}[framed]
        \tikzumlset{fill object = white, fill call = gray!20} 
        \begin{umlseqdiag}
            % class instances
            \umlobject[class=A]{a}
            \umlobject[class=B]{b}
            
            \begin{umlcallKill}[dt=3,op={functionName()}]{a}{b}
            \end{umlcallKill}
            
        \end{umlseqdiag}
    \end{tikzpicture}   
\end{document}
