【代码笔记】iOS-获得当前硬盘空间

一，代码。

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    NSFileManager *fm = [NSFileManager defaultManager];
    NSDictionary *fattributes = [fm attributesOfFileSystemForPath:NSHomeDirectory() error:nil];

    NSLog(@"容量%lldG",[[fattributes objectForKey:NSFileSystemSize] longLongValue]/1000000000);
    NSLog(@"可用%lldG",[[fattributes objectForKey:NSFileSystemFreeSize] longLongValue]/1000000000);

}
