With the NSFileManager, you can have informations about the filesystem
using :
- (NSDictionary *)fileSystemAttributesAtPath:(NSString *)path

it gives you a dictionary with the following informations :
- NSFileSystemSize
- NSFileSystemFreeSize

Can't you get the space used on a disk with these informations ?

you can also look at POSIX APIs (man statfs) :
int statfs(const char *path, struct statfs *buf);
int fstatfs(int fd, struct statfs *buf);

or maybe look at darwin's sources to see how they implemented 'df'
