问题描述

我有一个文件夹，里面只有几个文件.我该如何在不使用任何UI类的情况下获取这些文件?

I have a folder and inside that, few files. How can i get that files without using any UI classes?

下面给出的小例子将使问题更加清楚:

The small eg given below will make question more clearer:

假设在我的主文件夹中有一个文件夹Printers，在其中有三个文件夹Printer1，Printer2，Printer3.现在，每个子文件夹中都有xml文件，例如printer1文件夹中的printer1.xml，printer2文件夹中的printer2.xml，printer3文件夹中的printer3.xml.我必须浏览这些文件夹，并将打印机3.xml的路径存储在变量(类型为NSString)中.

Suppose in my home folder, there is a folder Printers, inside that there are three folders Printer1, Printer2, Printer3. Now inside each subfolder there is xml file like printer1.xml inside printer1 folder, printer2.xml inside printer2 folder, printer3.xml inside printer3 folder. I have to browse through the folders and store the path to printer3.xml in a variable (of type NSString).

请向我建议这样做的方法.
