If it's an issue with circular inclusion, try using @class A or B or C in place of an include.

To elucidate on user441669's (spiffy id!) answer, in your interface file (.h), you should generally declare classes only with @class. Then you #import them in your implementation (.m) file. More info in this SO Q/A.
