You should have one designated initializer which is called by all other

thank you for your details.
It is true that I am confused about the initializers.
Which initializer should I call from my initWithCoder method?
I can not call [super initWithCoder] because NSDocument does not have

If the C strings are being read in from a file, you can use the
stringWithContentsOfFile:usedEncoding:error: or
initWithContentsOfFile:usedEncoding:error: methods which will
try to guess the encoding and return the string and the encoding
it used back to you. But even these methods are just

That’s weird; usually it’s the C/ObjC compiler that warns about deprecation,
