"Reading notes" ios-automatic release Pool

When you use the classes in the foundation framework to do more processing work, you need a more resilient memory management mechanism, that is, to use a memory-free pool. The memory-free pool provides an object container, and each time an object sends a AOTUORELEASE message, the object's reference count does not really change, but instead adds a record to the memory release pool, which is the requirement for the object. Until the memory release pool sends a drain or release message, the object in the pool is notified when the pool is destroyed, and all release messages are sent to actually reduce the reference count by 1.
