A convenience initializer can call a designated initializer in a superclass.
I think this statement is true. But it's actually wrong. I don't understand the reason.

Remember this rule:
A convenience initializer may not call anything outside of its own class, but it must ultimately call a designated initializer.
You may have a few convenience initializers calling other convenience initializers, but one of them must call the designated initializer.
This may sound confusing, but just remember that a convenience init may never call outside of its class.
Hope this helps
