How can I retrieve the UDID on iOS?

Question

I was wondering if it was possible to find out the UDID of the user\'s iPhone. Can someone shed some light?

Answer 1

In IOS5 and above, use this one to find UDID

NSString *uuidString = nil;
CFUUIDRef uuid = CFUUIDCreate(NULL);
if (uuid) {
    uuidString = (__bridge NSString *)CFUUIDCreateString(NULL, uuid);
    CFRelease(uuid);
}
NSLog(@"UDID: [%@]", uuidString);
