MacOSX开发object-c获取UUID、SerialNumber方法

各种找，整理出来，备用

UUID：

- (NSString *)getUUID
{
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;
}

SerialNumber：
-(NSString *) getHardwareSerialNumber
{
NSString * ret = nil;
io_service_t platformExpert ;
platformExpert = IOServiceGetMatchingService(kIOMasterPortDefault, IOServiceMatching("IOPlatformExpertDevice")) ;

if (platformExpert) {
CFTypeRef uuidNumberAsCFString = IORegistryEntryCreateCFProperty(platformExpert, CFSTR("IOPlatformSerialNumber"), kCFAllocatorDefault, 0) ;
if (uuidNumberAsCFString) {
ret = CFBridgingRelease(uuidNumberAsCFString);
CFRelease(uuidNumberAsCFString); uuidNumberAsCFString = NULL;
}
IOObjectRelease(platformExpert); platformExpert = 0;
}

return ret;
}
