How to represent NSUUID as a string?

How can I convert a NSUUID to NSString?

NSString *url = [self mysql_process:ESTIMOTE_PROXIMITY_UUID];

- (NSString*)mysql_process:(NSUUID *)beacon_id
{

    NSString *strURL = [NSString stringWithFormat:@"http://path_to_php_file/mysql.php?id=%@", beacon_id];
    NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];

    return strResult;

}

When I try to NSLog the URL im getting a pointer, which shows me my NSUUID, ESTIMOTE_PROXIMITY_UUID in this case.

swift 3 version

Ex:

let uuidStringValue = "12345678-1111-2222-3333-4567891012B4"

let proximityUUID = NSUUID(uuidString: uuidStringValue)

   NSString *url = [self mysql_process:ESTIMOTE_PROXIMITY_UUID];

- (NSString*)mysql_process:(NSUUID *)beacon_id  {

    **NSString *strDeviceUUID = [beacon_id UUIDString];** // Converts NSUUID to UUIDString format

    NSLog(@"beacon_id : %@ strDeviceUUID : %@ ", beacon_id,strDeviceUUID);

    NSString *strURL = [NSString stringWithFormat:@"http://path_to_php_file/mysql.php?id=%@", strDeviceUUID];
    NSData *dataURL = [NSData dataWithContentsOfURL:[NSURL URLWithString:strURL]];
    NSString *strResult = [[NSString alloc] initWithData:dataURL encoding:NSUTF8StringEncoding];

    return strResult;
}

This function is present in NSUUID.h file of Foundation frameworks.

/* Return a string description of the UUID, such as "E621E1F8-C36C-495A-93FC-0C247A3E6E5F" */
- (NSString *) UUIDString;

If you want NSString from NSUUID. Use UUIDString of NSUUID...

    NSUUID *uuidStringRef = [[UIDevice currentDevice] identifierForVendor];
    NSString *stringRef = [uuidStringRef UUIDString];//you can replace uuidStringRef with your ESTIMOTE_PROXIMITY_UUID

Hope it helps you...!

NSUUID has a method: -(NSString*)UUIDString;. So:

NSString *uuidString = [yourNSUUID UUIDString]
