You will have to reference that class. Go to the .h file and type above @interface of MyClassTwo...

@class MyClassOne

And you create and object for MyClassOne inside the @interface of MyClassTwo and set that as a property and synthesize it

Now in the @implementation of MyClassTwo, you should be able to the access the properties of MyClassOne with the object of MyClassOne.

You would normally create model, an NSObject to hold the 'state' of your data and this can then be used by all of your controllers to render. The model will have properties for teams, players etc.
