How to write code using ARC feature of Objective C so that it can work on prior version of iOS?

As per my knowledge ARC is available from iOS SDK version 5. So if you are writing an Objective C code using ARC syntax/features...how does one ensure that it works on the prior version of iOS ?

Well... #ifdefs, lots of #ifdefs.

For example, from twitter-text-objc:

...
#if !__has_feature(objc_arc)
    [entity autorelease];
#endif
    return entity;
}

Here's an answer you may find relevant.
