This sounds like such a basic thing that I'm sure I'm missing something but I can't see it.
I have a method in an implementation (it got there because for the first time in my life I used an Extract Superclass refactoring to pull out a bunch of methods and properties)
- (UIButton*) buttonFor:(SEL)btnAction normal:(NSString*)imgNormal selected:(NSString*)imgSelected highlighted:(NSString*)imgHighlighted disabled:(NSString*)imgDisabled
I want that method in the interface because it's now used by two subclasses.
The Pull Up refactoring lets you pull a method up to a parent class or interface but not from implementation to interface.
The Move method won't let me select it - warning that the destination must be a different class.
I realise it's a one line copy and paste but it feels like a natural complement to having refactored a lot of code, to be able to go through and just click on declarations to move them between the implementation and interface.
