.m and .h

If I understood this correctly, you declare something like functions in the .m file. In the .h file you actually specify what that function is supposed to do.

Am I getting this correctly? If I am, could you please give me a more thorough explanation?

You have that backwards, and a little too vague.

The .h file is where you declare the "public" facing parts of the class (Both methods and properties). These are the parts that another class would be able to access.

The .m is where you actually write the methods, and is also where you would declare any "private" interface.
