Memory management in iOS is handled by the automatic reference counting (ARC) system. ARC manages the lifecycle of objects, automatically releasing them when they are no longer needed to free up memory.
1. Retain Count: Each object has a retain count, which keeps track of how many other objects refer to it.
2. Autorelease Pool: When an autorelease object is created, its retain count is incremented, and it's added to the current autorelease pool.
3. Release: When an object is sent the release message, its retain count is decremented by one.
4. Retain: If another object takes a reference to the original object, its retain count is incremented.
