Question

I am new to IOS, I worked on windows, there we have a concept message passing, using which we can send any message to any instance and get the work done. Likewise is there any way here in IOS?

thanks in advance.

Feroz,
Objective – C by default supports message passing, i.e. when you do something like this

[self calculateSum];

here you are passing message calculateSum to self.

Then objective-c runtime calls the method calculateSum on self.
