本文介绍了NSArray *NSSearchPathForDirectoriesInDomains函数的使用方法，详细解释了directory和domainMask参数，并列举了一些常用的directory类型，如NSLibraryDirectory、NSDeveloperDirectory等。

NSArray *NSSearchPathForDirectoriesInDomains(

NSSearchPathDirectory directory,

NSSearchPathDomainMask domainMask,

BOOL expandTilde);

参数

directory 类型有很多，说几个常用的

NSLibraryDirectory, // various documentation, support, and configuration files, resources (Library)
NSDeveloperDirectory, // developer resources (Developer) DEPRECATED - there is no one single Developer directory.
NSUserDirectory, // user home directories (Users)
NSDocumentationDirectory, // documentation (Documentation)
NSDocumentDirectory, // documents (Documents)

NSCachesDirectory // location of discardable cache files (Library/Caches)


domainMask

NSUserDomainMask , // user's home directory --- place to install user's personal items (~)
NSLocalDomainMask , // local to the current machine --- place to install items available to everyone on this machine (/Library)

IOS中的沙盒机制（SandBox）是一种安全体系，它规定了应用程序只能在为该应用创建的文件夹内读取文件，不可以访问其他地方的内容。所有的非代码文件都保存在这个地方，比如图片、声音、属性列表和文本文件等。 1.每个应用程序都在自己的沙盒内 2.不能随意跨越自己的沙盒去访问别的应用程序沙盒的内容 3.应用程序向外请求或接收数据都需要经过权限认证   查看模拟器的沙盒文件夹在Mac电脑上的存...
