Response to: Final code problem
The final projects also has some warnings that can be very easily fixed. (I remember the warnings were around in the last version too): IAWindowController.m needs: #import "MyDocument.h" and in IAWindowController.h this needs to be added: - (void)setImageToDraw:(NSImage *)image;

Showing messages 1 through 1 of 1.

• warnings can mean runtime errors later

  ie. that the compiler tried to guess what you meant which might not be correct during execution.
  
  These warnings don't show up on a second compile (after a clean).
  
  So, one should do a clean before a candidate final compile to catch them all if you want to be safe.
