As NSObject is also a protocol you could probably also do

supporting that protocol and partly because the NSObject protocol
doesn't have some of the NSObject methods I often end up using.
Or you can define your protocol as extending the NSObject protocol.
e.g.
@protocol Foo <NSObject>
// Methods
@end
No, you can't, else the compiler will complains if you do not override
all NSObject protocol methods in classes that conform to the Foo
protocol.
