The UDID is always returning zero data from keychain in IOS?

I had an application in which I am saving [[[UIDevice currentDevice] identifierForVendor] UUIDString] on keychain like this:

NSString *bundleId = [[[NSBundle mainBundle] infoDictionary] objectForKey:@"CFBundleIdentifier"];

NSString *strApplicationUUID;



if(![keychainItem objectForKey:(__bridge id)(kSecValueData)]){
        NSString *idfa = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
          NSLog(@"bundleId %@",idfa);
        [keychainItem setObject:idfa forKey:(__bridge id)(kSecValueData)];
        NSLog(@"saving item %@", [keychainItem objectForKey:(__bridge id)(kSecValueData)]);
         strApplicationUUID=[keychainItem objectForKey:(__bridge id)(kSecValueData)];
   }else{
        NSLog(@"saved item is %@", [keychainItem objectForKey:(__bridge id)(kSecValueData)]);

    strApplicationUUID=[keychainItem objectForKey:(__bridge id)(kSecValueData)];
    }

// NSString *strApplicationUUIDstr = [[NSString alloc] initWithData:[keychainItem objectForKey:(__bridge id)(kSecValueData)]
                                                 //encoding:NSUTF8StringEncoding];

NSLog(@"%@",strApplicationUUIDstr);
NSLog(@"%@",strApplicationUUID);

return strApplicationUUID;

But it is giving me always zero data.its not saving for the first time also ,can anybody help me on this?

Your App may be rejected due to Apple prevent use UDID:-

May it Help you:

-(NSString *)getUniqueDeviceIdentifierAsString
{

 NSString *appName=[[[NSBundle mainBundle] infoDictionary] objectForKey:(NSString*)kCFBundleNameKey];

 NSString *strApplicationUUID = [SSKeychain passwordForService:appName account:@"incoding"];
 if (strApplicationUUID == nil)
 {
    strApplicationUUID  = [[[UIDevice currentDevice] identifierForVendor] UUIDString];
    [SSKeychain setPassword:strApplicationUUID forService:appName account:@"incoding"];
 }

 return strApplicationUUID;
}
