You are mixing up Class name and Instance name. You also seem to have problems understanding the scope of an instance.

-1- change your instance name to lowercase initial - that is IBOutlet Year2010 *year2010;

-2- change your method names to lowercase initial - that is - (void)men:(double)speed

The compiler currently assumes that Men is a static class method, but you never defined it as such, hence the error.

[Year2010 Men:income];

From the code you've shown us, the Year2010 class doesn't have a method Men:. Why would you expect to be able to call it?

Maybe change the type of the variable Year2010 to Year2011?

Also, dear god, don't name your instances the same as your classes. This will be impossible to read and understand when you come back from lunch, let alone months from now.
