Question on Quiz

I tried to fill in the blanks on this quiz and it keeps giving me errors... What is wrong here?

Fill in the convenience constructor below for the class Song, which calls a designated initializer named: initWithSinger: (NSString*) singer

  • ( id ) ____________ : (NSString*) singer {return [[ ________ alloc] initWithSinger: _________];}

I tried these... initWithSinger, self, singer

A convenience constructor starts with the name of the class which in this case is Song. So your answer would be songWithSinger.
