A while back, we were discussing memory management and how that works when developing for the iPhone. This time, I will be talking about frameworks, which contain code that can make programming something easier, but isn’t necessarily needed in every program.

After discussing iPhone file types last week, we can move on to memory management. On the current version of the iPhone, there is only 128MB of RAM, which is far lower than the usual 2+GB we see on desktop and laptop Macs. iPhone developers must keep this in mind when they are designing their games and writing their code in order to reduce the number of crashes and give the user a great experience with their app.

Now that we’ve got beta testing out of the way, we can discuss the different file types found in XCode. When starting a new project, XCode allows developers to choose from a variety of different starting points for their applications. For iPhone developing, some of the options include Navigation Controller projects or Tab Bar Controller projects. These aren’t file types per se, but they do affect what files you start with.

A while back I wrote about my initial experience with the iPhone SDK and developing on that platform. It’s been a while since then, and I’ve learned a lot. In that time, I had finished my first app, and it came time for me to get some beta testers to make sure it worked on more than just my iPhone 3G. The Ad Hoc distribution process is certainly not as easy as it could be, but I think once you figure it out, it’s easy to crank out apps for beta testers.

With all of the frameworks and APIs Apple has made available for developing for the iPhone, most developers were easily able to catch on and quickly develop highly successful apps in a short amount of time. However, it seems as if Apple has made it so easy that even a nine year old can develop for the iPhone. Now if that’s not a great PR story, I don’t know what is. If you’ve seen or even downloaded the Doodle Kids application from the App Store, then you should know that it was developed by Lim Ding Wen from Singapore.

In a move that will please millions of people, and is surely a response to the launch of Google’s completely open Android platform, Apple has lifted the Non Disclosure Agreement it had previously placed upon every single iPhone developer. iPhone developers worldwide were up in arms in the months proceeding the launch of the App more »
