I'm not sure whether I've interpreted your question correctly, but if b is an object instance of the B class, and methodB is a method of the B class, you can call methodB via:

[b methodB];

I am assuming by "function", you actually mean "method"...?

Alloc and init an instance of this class and call your method. Class "functions" are called methods.

BController *myBController = [[BController alloc] init]; // alloc and init Controller B
[myBController MethodB]; // Call your class method
[myBController release]; // release your instance object

Any questions? Just comment.
