Difference between release and dealloc in objective-c

Question

When deallocing a refrence I\'ve seen release and dealloc being used for example

-(void)dealloc
{
  [foo release];
  [nar dealloc];         


        

Answer 1

The dealloc statement in your example is called when the object's retain count becomes zero (through an object sending it a release message).

As it is no longer needed, it cleans itself up by sending a release message to the objects that it is holding on to.
