Do not use getters and setters in -init. You should be accessing the ivars directly.

While we're on this topic, I think a more important problem with the above is the assumption that [super init] either returns nil or the current value of self.


It should of course be

  if ((self = [super init])) {
    // Initialise
  }
  return self;

or some equivalent construct.

Kind regards,

Alastair.
