Saving PlayerPrefs in iOS.?

On the PlayerPrefs page from the Reference Docs, it mentions where PlayerPrefs are stored on MacOSX, Windows and web players, but not iOS.

So I am wondering, when using playerPrefs in iOS, what is the basic technique? For instance, is doing something like this the way to go?

function endRound()
{
enemiesKilled = enemiesKilled;
PlayerPrefs.setInt(enemiesKiled);
}

I know my coding is rough but is referencing and storing the saved items done just in any old script?

Yes, it works the same in every platform.

Right thanks.
