You also could filter your array with a NSPredicate, like this:

NSArray *items = [names filteredArrayUsingPredicate:[NSPredicate predicateWithFormat:@"self contains[cd] %@",searchText]];

You are doing it right. What is the problem? You can also do it like:

for (NSString *sTemp in names)
    {
        NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch];
        if (titleResultsRange.location != NSNotFound)
            [Items addObject:sTemp];
    }
