The autorelease pool in main() is used as a catchall ... to ensure that
objects not created in other pools last for the lifetime of the program.

The autorelease pools are not normally used directly, instead the
-autorelease method (which all objects inherit from NSObject) is
generally called.  This method adds the receiver to the newest
autorelease pool in the executing thread.

May methods create and destroy autorelease pools, so that any
temporary objects they create are destroyed before they return.

You can do the same in your own code.
