Memory management is the process of keeping track of objects in your applications and “freeing” objects that you no longer want to keep around (otherwise nasty memory leaks can occur). On the Mac, you can optionally allow Objective C to deal with the memory management on your behalf, but as an iPhone developer, it’s a necessary chore – Apple considers automatic memory management to be too performance intensive. We’ve collected together several of the most useful iPhone memory management related resources we could find and linked them below.
They’re not all iPhone specific and they range from ultra simple to reasonably complex.. so dive in: Memory Management from Wikipedia - What is memory management? If you’re asking yourself that question (despite the explanation above) check out this solid introduction to the general concepts from Wikipedia.

My goal is to write a blog entry for each day of the class, so we'll see how that goes. See here for a list of each day's blog entries.

App Icon and Default Image After getting the initial iPhone app up and running we added an icon for the application which is what displays on the iPhone "desktop" and added a default image, the purpose of which is to "fool" the user into thinking the application launched immediately without delay.

And if you want a sexily awesome looking UI view, like the view of the Surf Report app (see right or free on AppStore ) that was released on the AppStore recently, then the WebKit is just the best thing since the electric bread slicer for speed of development.
Holy grail of iPhone development? Well, that’s what we thought. This article is about good and bad things. Its probably wonderfully useful stuff to know. Negatives So first the downsides. When the WebKit is first loaded into memory, and we try to do this behind the scenes as soon as we get control of our app from the OS, it can take a good few seconds for your WebKit object to be available. . - (void)webViewDidFinishLoad:(UIWebView *)webView You’re running an interpreter (JavaScript runtime) on top of a device with a small CPU and small memory.
