Why not use will/didChangeValueForKey?


- (NSImage*)myImage
{
  if ( myImage == nil )
  {
    [self willChangeValueForKey:@"myImage"];
    myImage = [[self fetchImageFromDisk] copy];
    [self didChangeValueForKey:@"myImage"];
  }  
  return myImage;
}

Any code that acts on the image can be put into a third method used by the setter and getter.
