How to get UDID of iOS Device Programmatically in iOS 7

Question

i am using the below code to display the UDID of the device. But its displaying the null value

i.e. 2014-05-12 11:56:06.896 LoginScreen[195:60b] deviceUDID: (null)

NSUUID *deviceId;
deviceId = [UIDevice currentDevice].identifierForVendor;
NSLog(@"deviceUDID: %@",deviceID);

Sorry to all of you. I made a silly mistake

Here NSUUID instance is deviceId and i am printing deviceID in NSLog :)

Now it is working for me. Thanks to everyone

A side note: this would be UUID and not UDID: [http://nshipster.com/uuid-udid-unique-identifier/]. — Rok Jarc, May 12 '14 at 06:52

In order to get UUID of the device you can use the following line of code

[[[UIDevice currentDevice] identifierForVendor] UUIDString];

But you have to check whether the app is running on simulator or on device.

hope this helps you.

Apple has hidden the UDID from all public APIs, starting with iOS 7. Any UDID that begins with FFFF is a fake ID.

so you mean to say that there is a no way to get UDID of the device in iOS 7 above – Brijesh Singh May 12 '14 at 06:50
yes but you can use advertising identifier instead of UDID – Gajendra Rawat May 12 '14 at 06:55
OP is asking about `identifierForVendor` - which should be available. `advertisingIdentifier` can be opted out by user via settings. – Rok Jarc May 12 '14 at 06:56

Objective-C :

NSString *strUUIDValue = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    NSLog(@"strUUIDValue : %@", strUUIDValue);

Swift 2 :

let UUIDValue = UIDevice.currentDevice().identifierForVendor!.UUIDString
        print("UUID: \(UUIDValue)")

NSString *string = [[[UIDevice currentDevice] identifierForVendor] UUIDString]; 
string = [string stringByReplacingOccurrencesOfString:@"-" withString:@""]; 
string = [NSString stringWithFormat:@"%@%@",@"FFFFFFFF",string];

Try this

NSUUID *deviceId;
#if TARGET_IPHONE_SIMULATOR
deviceId = [NSUUID initWithUUIDString:@"UUID-STRING-VALUE"];
#else
deviceId = [UIDevice currentDevice].identifierForVendor;
#endif

OR

   NSString *uuid = nil;
   CFUUIDRef theUUID = CFUUIDCreate(kCFAllocatorDefault);
   if (theUUID) {
    uuid = NSMakeCollectable(CFUUIDCreateString(kCFAllocatorDefault, theUUID));
   [uuid autorelease];
   CFRelease(theUUID);
  }
