objective-c - Does "alloc" methods produce an instance ?

Question

When I write:

MyClass *obj = [[MyClass alloc]init];

I can split in 2 parts:

• [MyClass alloc] --->> produce something

• [theProduct init];

So alloc is a Class methods and being init an instance method i suppose that it must be called on an instance...in this case the result of [MyClass alloc]. I'm really confused about that.

Are my conjectures correct?

Answer 1

+alloc allocates and zeroes the memory for an instance of a class. This instance is uninitialized—it's not ready to be used as an object until you initialize it with -init or related.
