Question

I’m looking at using openUDID inside my app for registration purposes.

However its still using the UDID number apple issues and so I was just reading though the .m file and came across this:

// One day, this may no longer be allowed in iOS. When that is, just comment this line out.
    //
#if TARGET_OS_IPHONE    
    if([UIDevice instancesRespondToSelector:@selector(uniqueIdentifier)]){
        _openUDID = [[UIDevice currentDevice] uniqueIdentifier];
    }

#endif

    // Take this opportunity to give the simulator a proper UDID (i.e. nullify UDID and create an OpenUDID)
    //
#if TARGET_IPHONE_SIMULATOR
    _openUDID = nil;
#endif

    // Next we try to use an alternative method which uses the host name, process ID, and a time stamp
    // We then hash it with md5 to get 32 bytes, and then add 4 extra random bytes
    // Collision is possible of course, but unlikely and suitable for most industry needs (e.g.. aggregate tracking)
    //

However I’m not sure exactly what line to comment out so that it used the alternative method which uses the host name, process ID, and a time stamp

Answer 1

You would comment out the 3 lines of code in the TARGET_OS_IPHONE block
