objective c - mutually referencial .h files? -


I'm sure that I'm really feeling dumb when I remember how to do it, but here It is:

I have two classes A and B is B. A type of B, B is a type of B. It is not uncommon. The problem is that B.H. Import and vice versa. However, one of these should be first, and when this happens, the other uses fail to compile.

I know that there is really a dumb / easy way to do this, and I do not remember it, and today my google-fu is weak ...

In Objective-C, you can declare a class using @ class classname . Before you use it in A, then you use @class A and @class B before using it in B.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
