How to represent NSUUID as a string? - ios

Question

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.

Answer 1

NSUUID has a method: -(NSString*)UUIDString;.
So:
NSString *uuidString = [yourNSUUID UUIDString]

Answer 2

swift 3 version
Ex:
let uuidStringValue = "12345678-1111-2222-3333-4567891012B4"
let proximityUUID = NSUUID(uuidString: uuidStringValue)

Answer 3

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...!

Answer 4

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;
