一款使用简单但功能强大的文件操作类库

项目介绍：

简单实用的iOS文件工具类

HYFileManager一个基于NSFileManager的文件操作类，它提供一系列的静态方法，只用少量的代码，来处理经常需要处理的文件操作，使得工作更加方便快捷。

要求

iOS >= 5.0
ARC环境

特性

沙盒日常操作目录集合，简单语法即可获取目录路径；
遍历文件夹，包含两种方式，深遍历和浅遍历；
获取文件属性，包含单个属性获取方法和所有属性获取方法；
创建文件(夹)，创建文件夹，文件，可以根据所需，是否需要覆盖，是否需要默认内容来创建；
删除文件(夹)，提供两个静态方法来快速实现清空Caches和tmp文件夹内容；
复制、移动文件(夹)，可以选择是否需要覆盖来对文件(夹)进行复制和移动；
根据目录路径来获取文件名和文件扩展类型；
判断文件(夹)是否存在、文件(夹)判空、判断路径是否为文件或者文件夹、已经判断目录是否可读可写；
获取文件(夹)的大小，提供两种返回方式，NSNumber和NSString，方便开发使用；
写入文件内容，支持基本数据类型、NSData、UIImage和NSCoding类型。

查看 HYFileManager.h，获取方法详细介绍。

安装

CocoaPods:

pod 'FCFileManager'

下载HYFileManager:

下载HYFileManager，将HYFileManager拖动到你的使用工程中即可。

使用实例
