从按钮执行 Unix 命令 - XCode Objective - C

Question

您好，我在从按钮执行 Unix 命令时遇到问题。

这是我目前所拥有的：

如果有人可以提供帮助，那就太好了。基本上我正在做的是插入一个文件，设置目标然后程序将解压缩该文件。我有一个打开的对话框来选择一个 pup 文件，然后是一个保存对话框来选择保存目标。然后我有一个解压按钮，它目前什么都不做。解压按钮需要参数。如果有人可以提供帮助，那就太好了。

我是 Objective-C 的新手，我试图找到尽可能多的信息，但我似乎无法让它发挥作用。这是我正在使用的 unix 应用程序。

您可能需要添加文件名和目标目录作为命令参数：

[pupunpack setArguments:[NSArray arrayWithObjects:tVarFilename, tvarDirectory, nil]];
