With the front end in the past, it’s time to talk about the back end of developing for the iPhone. More specifically, the API system that many websites are implementing to make developing applications for their sites easier and easier every day. Twitter, Facebook, Flickr, Google Analytics, and many other sites now have them and have been using them for a while to benefit everyone.

This week I am going to talk about what it is like after you get your apps out there and into the world. This is truly where the real fun begins. First, there is the initial excitement of people out there enjoying something you have spent many hours on. It is great to see something you put your heart into during its development actually make it out into the real world. Then, you realize that although it can feel great, your job isn’t done.

This week I will be discussing some resources where you can find information if you want to get started or need help with developing for the iPhone. There are many places that can be found for this type of thing, and Apple provides developers with a plentiful amount of resources such as guides and what not. However, some are better than others.

This week I wanted to talk about some of the Twitter and Facebook APIs available for the iPhone SDK. API stands for application programming interface, and it allows developers outside of the company to access certain functions and data that Twitter and Facebook make available. For example, developers can access Twitter tweets through an API, but they don’t have direct access to them. In other words, their access is limited, in a way. However, the guys at both Twitter and Facebook have created some great APIs to help get started with developing applications for their web apps on the iPhone.
