Principle of OC message sending and forwarding mechanism

Objective-C (OC) is an object-oriented programming language with unique mechanisms in message passing and method invocation. In OC, objects call methods through messages instead of calling functions directly like traditional programming languages. This article will deeply explore the principles of OC’s message sending and forwarding mechanism, including its basic concepts, implementation process, code examples, and […]
