Unique identifier for an iPhone app

Question

For an iPhone app that submits images to a server I need somehow to tie all the images from a particular phone together. With every submit I\'d like to send some unique pho

Answer 1

I had success with such code:

- (NSString *)stringUniqueID {
    NSString *  result;
    CFUUIDRef   uuid;
    CFStringRef uuidStr;
    uuid = CFUUIDCreate(NULL);
    assert(uuid != NULL);
    uuidStr = CFUUIDCreateString(NULL, uuid);
    assert(uuidStr != NULL);
    result = [NSString stringWithFormat:@"%@", uuidStr];
    assert(result != nil);
    NSLog(@"UNIQUE ID %@", result);
    CFRelease(uuidStr);
    CFRelease(uuid);
    return result;
}
