When should use the "[super dealloc];"? Could anyone list all of case.


Whenever you have overridden -dealloc. Simple as that.

When do you override dealloc? When there are instance member variables (ivars) that must be released when your object is deallocated. While these will usually be also allocated at init time, there's no reason that there should be exact symmetry, so looking for it as a "rule" is misguided.
