Oh, I forgot to add - specifically you can either override -
[UIViewController didReceiveMemoryWarning] or listen for the (this is
from memory, so verify it with the docs)
UIApplicationDidReceiveMemoryWarningNotification notification if you
need to do something in other than a view controller.

The proper way to manage large objects that can be easily reloaded
as needed is to make sure and respond to memory warnings. The exact
amount of memory available to your application depends on both the
device (which could vary greatly in terms of hardware resources) and
other processes running in the background (like MobileMail, for
instance). Luckily for you, the OS handles determining when you're
running low on memory and sends notifications to that affect (as
well as doing other things).

I'm writing an app for the iPhone, but I need to be mindful how
much virtual memory there is available to the app when it runs, so
I can manage allocing and deallocing some large arrays. I'm
guessing that the OS runs in a small amount (100MB?) of flash
memory compared to the 16GB or 32GB of general storage memory?
Also, is there a system call I can invoke from within my app to
determine how large it is getting?
