For as active as iPhone application development community is, achieving success in iTunes has been an elusive affair for those who participate in this vertical. The two main obstacles presented to anyone who wants to create an iPhone applications are: one, finding resources/developers with the right skill set; and two, marketing the application after the application has been submitted.

The NSArray is a huge workhorse that we use quite frequently without even thinking about it. The NSArray class isn’t just your ordinary array. Not only does it provide random access, but it also dynamically re-sizes when you add new objects to it. While I won’t go over every method in NSArray (there are quite a few), I will discuss some of the more important ones that are most commonly used. Let’s take a closer look at this class.
