Grabbing a specific element of an array in Objective-C

I'm splitting a string by ';', but want to specifically grab the first and second element.

I know with PHP it's just simply $array[0], just can't find anything for this for Objective-C

NSArray *tempArray = [returnString componentsSeparatedByString:@";"];

So here I have assigned my array, how can I go about getting the first and second element?
