I am wondering the correct/recommended technique to make a NSMutableArray out of a NSArray.

How about -mutableCopy?

which gives you a retained object, and then there is +[NSMutableArray arrayWithArray:], which gives you a temporary object.

I see online that there are ways to do this, but am not
sure what is the best way.

So I use either, depending on whether I want retained or temporary. I suspect that it probably doesn't make it damned bit of difference because all this "mutable" and "copy" fluff gets optimized away under the hood anyhow.
