Absolutely not. Write your code to work with any order. In this case,
what you should do is write your data source to nil out the table's
reference to it when it goes away:
- (void)dealloc {
[tableView setDataSource:nil];
[super dealloc];
}
What prevents the tableview from being dealloced before the
datasource? In that case the datasource is messaging a stale pointer.
I think that something higher up in the ownership graph needs to
manage this, like the window controller.
