Is there a sure-fire way to know when it is necessary to call super in an
override?
Sample code shows that calling super is necessary for methods such as
-(id)init
- (void)windowControllerDidLoadNib
but not for
(NSData *)dataOfType
(BOOL)readFromData
How can you know for sure?

Is there a sure-fire way, no. It’s usually fairly clear however. Normally you
call super if you override a method unless it tells you not to in the
documentation or you are clearly trying to make something NOT do what the
superclass did. I suppose my handwaving rule is if a method ‘does’

Checking the docs is best, but sometimes the compiler will warn you if you fail
to call super, if the method was tagged with NS_REQUIRES_SUPER.
