Is oneway supported in iOS4?

Question

Looking at this article: http://www.galloway.me.uk/tutorials/singleton-classes/

I have implemented a singleton, my question is the oneway (not using ARC) is it supported in iOS 4.0?

Answer 1

Yes it is available, oneway is an objective c keyword, it does not relate to a given iOS SDK

Answer 2

This is a design pattern which will remain unchanged as and when technology changes. So you can use it easily.

Answer 3

Yes , oneway keyword is a compiler hint.
