Objective-C's autorelease mechanism is related to managing the lifecycle of objects without the need to manually call release immediately after use. When an object is created using methods that return an object with a +1 retain count, it can be added to an autorelease pool by calling autorelease. This means the object will be automatically released later when the pool is drained.

An autorelease pool is a stack that collects objects marked for automatic release. Typically, the pool is created and drained in event loops or at specific points in the program.

Example:

NSObject *obj = [[NSObject alloc] init];
[obj autorelease];
// obj will be automatically released when the current autorelease pool is drained

This simplifies memory management, allowing temporary objects to live long enough to be used, without requiring the programmer to explicitly call release everywhere.
