Today a question came to my mind, which method for accessing NSArray elements is more efficient, objectEnumerator or objectAtIndex?
This is pretty easy to test yourself. Just iterate over a large array (100,000 elements might be sufficient depending on the speed of your computer) using both approaches printing the time before and after the iterations.
With a particularly large array, I was concerned about this eons ago. I found that using an Enumeration was somewhat slower, but for smaller arrays, the difference was insignificant in the grand scheme of things. But things may have changed now, so a quick test might be worthwhile.
