1.0 Events in iOS

There are a variety of events that occur during the user's use of the app, and the events in iOS can be divided into 3 major types: Uikit recognizes three types of input events:

Touch events Accelerometer Event/Motion Event Remote control Events

Uiresponder-Responder Object Concept:

Not all objects in iOS can handle events, only objects that inherit Uiresponder can receive and handle events.

Members:

UIApplication, Uiviewcontroller, and UIView inherit from Uiresponder, so they are both responder objects that can receive and handle events

Internal methods of Uiresponder:
