In this specific instance i was looking for intersecting strings from two arrays.
Nevertheless, I'm always curious to see how people solve various problems, so if you're willing to share, please pass along a code snippet.
NSArray first, second; //assume they exist and contian your strings
NSSet firstSet = new NSSet(first);
NSSet secondSet = new NSSet(second);
NSSet intersectingsSet = firstSet.setByIntersettingSet(secondSet);
NSArray myIntersectedArray = intersectingsSet.allObjects();
TIA.

Are you looking for a substring of a string in an array? Or are you looking for the whole string? I have written a routine to find the substring of a string in an array, if that would help.

Thanks all...
it was a matter of upper/lowercase.
Well, can you insert a toLowerString() while creating the array? if not, you must iterate over the array and check each element after use toLowerCase().
for exaple:
NSArray first, second
for(int i = 0; i < first.count(); i++)
{
String elemFirst = (String)first.objectAtIndex(i);
for(int j = 0 ; j < second.count(); j++)
{
String elemSecond = (String)second.objectAtIndex(j);
if(elemFirst.equalsIgnoreCase(elemSecond))
{
//Do what you need to do
}
}
}

That and make sure you aren't using "contains(Object element)" as that is not the same as "contains
Object(Object object)". This bit me a couple times before I quit making that mistake - usually in the wee hours of the morning.

Yap. containsObject compares objects using equals(), so it should work for Strings. If you are not finding the string with this, it's because it's not on the array. :) Maybe you need to trim() some white spaces?
