[Reading Notes] iOS-Automatically releases the pool and Reading Notes ios-

When you use classes in the Foundation framework for more program processing, you need a more flexible memory management mechanism, that is, to use the memory release pool. The memory release Pool provides an object container. Every time an object sends an aotuorelease message, the reference count of the object does not actually change. Instead, it adds a record to the memory release pool, which meets the object requirements. Only when the memory release pool sends a drain or release message, that is, the objects in the pool will be notified before the pool is destroyed. Only when all the release messages are sent Will the reference count be actually reduced by 1.
