!foo vs foo == nil


  • Subject: !foo vs foo == nil
  • From: Torsten Curdt <email@hidden>

This question has come up during the last CocoaHeads and no one was really able to give a definite answer.
Do both expressions really mean the same thing (as nil is not null)?


 if (!foo) {
 ...
 }

 if (foo == nil) {
 ...
 }

cheers
