objective c interface inheritance

The @interface in Objective-C has nothing to do with Java interfaces.
It simply declares a public interface of a class, its public API. (And member variables, as you have already observed.) Java-style interfaces are called protocols in Objective-C and are declared using the @protocol directive.

Can we use inheritance in interface?

Java allows multiple inheritance using interfaces.
Interfaces could only define abstract methods, that is, methods without any implementation.

Does Objective-C have multiple inheritance?

In keeping with its clean and simple design, Objective C does not support multiple inheritance, though features have been developed to replace some of the functionality provided by multiple inheritance (see run-time section below).
The root of the Objective C class hierarchy is the Object class.

Which inheritance is not supported by Objective-C?

Because multiple inheritance is not supported by Objective-C, inheritance hierarchies can only be implemented in Objective-C using single inheritance._{14 jui. 2023}
