Answer from AI
The main stages of an object's lifecycle in programming typically include:
- Creation (initialization) — the object is allocated in memory and initialized (constructor, setting initial values).
- Usage — the object performs its functionality, methods are called, properties are modified.
- Resource release — if the object uses external resources (files, network, memory), they are released.
- Destruction (deinitialization) — the object is removed from memory, for example, by a garbage collector or manually.
In iOS, for example, the lifecycle of a UIViewController includes methods viewDidLoad, viewWillAppear, viewDidAppear, viewWillDisappear, viewDidDisappear, and deinit, which reflect the stages of creation, display, and destruction of the object.
Understanding the lifecycle helps to properly manage resources and object states.
