Objective-C passing methods as parameters

Question

How do you pass one method as a parameter to another method? I\'m doing this across classes.

Class A:

+ (void)theBigFunction:(?)func{
    // run the func

Another option is to look at blocks. It allows you to pass a block of code (a closure) around.

Here's a good write up on blocks:

Here's the apple docs:
