That could also be dangerous. What if the parser sets up its own
autorelease pool while walking the XML document? You could have a
situation like this:
- (void) parse {
[self doSomething];
while (notDone) {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
[delegate callbackMethod];
[pool drain];
}
[self doSomethingMore];
}
What you're suggesting would put the parser into the inner autorelease pool!
I still maintain that it's never safe to release/autorelease an object
from inside one of it's delegate calls. If it works at all, you're
implicitly relying on an implementation detail that's subject to
change.
