Question

我有一个Cocoa应用程序，允许用户通过在NSTextBox等UI项目中输入命令来执行shell命令（就像使用终端一样）。应用程序允许有一些预定的参数，这些参数将转换为应用程序内的某些字符。

该应用程序还允许多线程，其中可以同时运行一些命令。

我现在面临的挑战是让用户输入命令，因为它在终端中具有所有空格等。我很难分解用户输入的NSArray元素是要被提供给NSTask的参数。例如，存在一些在其间具有空间的路径或参数，例如， / users / Application Support / testFolder /或 'test - b'

我现在正在做的是我有固定数量的NSTextBoxes，每个NSTextBox只允许1个参数。另一个问题是，如果某个命令的参数数量少于我的总NSTextBox，我必须给参数赋予“”，因此，命令可能无法正确执行。我想让用户更加灵活地按原样输入。然后，我的应用程序能够处理字符并使用NSTask运行用户输入的命令。
