本文介绍了使用Objective-C获取iOS模拟器中应用程序沙盒路径的方法，并通过实例展示了如何访问Documents、Library、Caches等关键目录。

NSString *path = NSHomeDirectory();

上面的代码得到的是应用程序目录的路径，在该目录下有三个文件夹：Documents、Library、temp以及一个.app包！

该目录下就是应用程序的沙盒，应用程序只能访问该目录下的文件夹！！！

请参考下面的例子：

NSString *path1 = NSHomeDirectory();
NSLog(@"path1:%@", path1);

path1:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830

2、

NSString *path2 = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];


NSLog(@"path2:%@", path2);

path2:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Library/Caches

3、

NSString *path3 = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];

NSLog(@"path3:%@", path3);

path3:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Documents

4、

NSString *path4 = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];

NSLog(@"path4:%@", path4);

path4:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Documents

5、

NSString *path5 = [NSHomeDirectory() stringByAppendingPathComponent:@"Library"];

NSLog(@"path5:%@", path5);

path5:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/Library

6、

NSString *path6 = [NSHomeDirectory() stringByAppendingPathComponent:@"temp"];

NSLog(@"path6:%@", path6);

path6:/Users/xxx/Library/Application Support/iPhone Simulator/4.2/Applications/172DB70A-145B-4575-A31E-D501AC6EA830/temp
