Objective-C does not support Multiple Inheritance.

Typically, you work around this by using protocols when you want to program to an interface.

@interface SomeClass : NSViewController < SomeProtocol >
@end

Another option is composition:

@interface SomeClass : NSObject
{
@private
  NSViewController * viewController;
  NSTableViewController * tableViewController;
}
@end
