A Practical Tools Of File Operations

HYFileManager is a simple tool of iOS file operations base on NSFileManager. It offers a range of static methods, only a small amount of code to handle file operations often need to deal with, making work easier and faster.

中文说明

Requirements

• iOS >= 5.0
• ARC enabled

Features

• operate sandbox directory, use a simple syntax can be operated sandbox directory;
• traverse folder, based on deep values, and access the list of subdirectories;
• Get the file attributes, Including a list of all the attributes or a single attribute;
• Create a file, including the creation of folders, you can also choose whether content or overwrite parameters;
• Delete file, including deleted folder, two new static methods, you can clear the caches and tmp folders
• Copy and move file, including folder, you can easily move and copy the file;
• Get the filename and extension type;
• Determine whether a file exists, whether the file is empty, and whether the file is readable and writable;
• Get file size，include folder size, and provide two ways to return;
• Write to the file contents, support for basic data types, NSData, UIImage and NSCoding.

See HYFileManager.h, and get detailed methodology description.

Installation

Manual install:

Copy HYFileManager.h and HYFileManager.m to your project.
