Applications for mobile platform are increasingly becoming an important market sector for all kinds of service providers. With the growing popularity of the iPhone and Apple’s well designed SDK, there are plenty of iPhone development project offerings even in this slow economic scenario. At Summa, we recently had a great experience developing a sleek iPhone application with a large user base. The purpose of this blog is to put together conceptual information along with project experiences around the important aspects of Objective-C’s memory management that would be helpful as one begins to delve deep into iPhone development.
