iOS开发之cocoa获取Mac设备硬件信息（序列号、UUID））

由于最近开发一款Mac软件，需要获取Mac电脑的一些硬件信息，做唯一设备认证。网上资料不多，但最终还是找到了一些，这里做下汇总记录。这里主要写了，获取设备序列号、UUID、硬盘序列号。设备序列号也就是用做苹果官方查询认证的序列号。获取硬盘序列号代码暂时无从考证正确性。但是设备序列号、UUID，亲测都是准确的。获取设备硬件信息，其实iOS/Mac OS下有个IOKit.framework框架。

///1.获取设备的UUID，这里记录两种方法

//方法一
- (NSString *) get_platform_uuid {
    io_registry_entry_t ioRegistryRoot = IORegistryEntryFromPath(kIOMasterPortDefault, "IOService:/");
    CFStringRef uuidCf = (CFStringRef) IORegistryEntryCreateCFProperty(ioRegistryRoot, CFSTR(kIOPlatformUUIDKey), kCFAllocatorDefault, 0);
    IOObjectRelease(ioRegistryRoot);
    NSString * uuid = (__bridge NSString *)uuidCf;
    CFRelease(uuidCf);
    return uuid;
}

//方法2，代码执行终端命令获取
- (NSString *)GetHardwareUUID
{
    NSTask *task;
    task = [[NSTask alloc] init];
    [task setLaunchPath: @"/usr/sbin/ioreg"];
    
    //ioreg -rd1 -c IOPlatformExpertDevice | grep -E '(UUID)'
    
    
    NSArray *arguments;
    arguments = [NSArray arrayWithObjects: @"-rd1", @"-c",@"IOPlatformExpertDevice",nil];
    [task setArguments: arguments];
    
    NSPipe *pipe;
    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];
    
    NSFileHandle *file;
    file = [pipe fileHandleForReading];
    
    [task launch];
    
    NSData *data;
    data = [file readDataToEndOfFile];
    
    NSString *string;
    string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
    
    //NSLog (@"grep returned:n%@", string);
    
    NSString *key = @"IOPlatformUUID";
    NSRange range = [string rangeOfString:key];
    
    NSInteger location = range.location + [key length] + 5;
    NSInteger length = 32 + 4;
    range.location = location;
    range.length = length;
    
    NSString *UUID = [string substringWithRange:range];
    
    
    UUID = [UUID stringByReplacingOccurrencesOfString:@"-" withString:@""];
    NSLog(@"UIID:%@",UUID);
    
    return UUID;
}

///2.获取mac设备序列号，同样贴出两种获取方式

方式1
NSString * GetHardwareSerialNumber()
{
    NSString * ret = nil;
    io_service_t platformExpert ;
    platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice")) ;
    
    if (platformExpert)    {
        CFTypeRef uuidNumberAsCFString ;
        uuidNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, CFSTR("IOPlatformSerialNumber"), kCFAllocatorDefault, 0) ;
        if (uuidNumberAsCFString)    {
            ret = [(__bridge NSString *)(CFStringRef)uuidNumberAsCFString copy];
            CFRelease(uuidNumberAsCFString); uuidNumberAsCFString = NULL;
        }
        IOObjectRelease(platformExpert); platformExpert = 0;
    }
    
    return ret;
}

///方式2

    NSTask *task;

    pipe = [NSPipe pipe];
    [task setStandardOutput: pipe];
    
    NSFileHandle *file;
    file = [pipe fileHandleForReading];
    
    [task launch];

    data = [file readDataToEndOfFile];
    
    NSString *string;
    string = [[NSString alloc] initWithData: data encoding: NSUTF8StringEncoding];
    
    //NSLog (@"grep returned:n%@", string);
    
    NSString *key = @"IOPlatformSerialNumber";
    NSRange range = [string rangeOfString:key];
    
    NSInteger location = range.location + [key length] + 5;
    NSInteger length = 32 + 4;
    range.location = location;
    range.length = length;
    
    NSString *SerialNumber = [string substringWithRange:range];
    
    
    SerialNumber = [SerialNumber stringByReplacingOccurrencesOfString:@"-" withString:@""];
//    NSLog(@"SerialNumber:%@",SerialNumber);
    
    return SerialNumber;
}
