iOS开发 - 如何获取设备的总容量和可用容量 网络运营商 3g/wifi判断 手机型号

镔哥最近开发需获取手机容量，其实这你是一个很好的例子

//硬盘容量

- (float)getTotalDiskSpace

{

    float totalSpace;

    NSError * error;

    NSDictionary * infoDic = [[NSFileManagerdefaultManager] attributesOfFileSystemForPath:[selfgetHomeDirectory]error: &error];

    if (infoDic) {

        NSNumber * fileSystemSizeInBytes = [infoDicobjectForKey: NSFileSystemSize];

        totalSpace = [fileSystemSizeInBytes floatValue]/1024.0f/1024.0f/1024.0f;

        return totalSpace;

    } else {

        NSLog(@"Error Obtaining System Memory Info: Domain = %@, Code = %ld", [errordomain], (long)[errorcode]);

        return 0;

    } 

}

- (NSString *)getHomeDirectory

{

    NSString * homePath = NSHomeDirectory();

    return homePath;

}

/*

+ (NSNumber *)totalDiskSpace

{

    NSDictionary *fattributes = [[NSFileManagerdefaultManager] attributesOfFileSystemForPath:NSHomeDirectory()error:nil];

}

+ (NSNumber *)freeDiskSpace

{

    NSDictionary *fattributes = [[NSFileManagerdefaultManager] attributesOfFileSystemForPath:NSHomeDirectory()error:nil];

    return [fattributes objectForKey:NSFileSystemFreeSize];

}

//手机型号（这跟系统获取的不一样，这是获取iPhone5，4，6之类的）要导入

    NSLog(@"NOTE: Unknown device type: %@", deviceString);

    return deviceString;
