Answer / Reshu Agarwal
Autorelease pools in iOS are used to manage memory for objects that are created and released asynchronously. When an object is sent the 'autorelease' message, it is added to the nearest autorelease pool. The Objective-C runtime will then automatically release these objects at certain points during the run loop, ensuring that memory is properly managed.
