recipe 1.10. Managing Memory with the iOS SDK

1.10.1. Problem

You want to allocate, deallocate, and use autorelase objects in Objective-C without causing memory leaks.

1.10.2. Solution

Each object allocated in the Objective-C runtime has a retain count. The retain count can be thought of as the number of references that have been made to the current object. Once the retain count is zero, the object will be deallocated.
