Any problems with the following codes?
- (void) dealloc {
self.foo = nil;
}
Instead of
- (void) dealloc {
[_foo release];
_foo = nil;
}
There are two reasons not to do the former:
If a subclass has overridden the setter, the release might not actually happen.
Using the setter might trigger a KVO notification and the observer will receive a notification from an object that technically doesn’t exist.
On the other hand, if you use ARC, you don’t need to do any of that.
