That document describes the scenario where you destroy your data objects, not where you destroy the data source yourself. The call to setDataSource: is sufficient, as it can no longer query you after that point. In general, you always need to clear any weak references to your objects when they are deallocated. This is most well known for the weak references you get from NSNotificationCenter, but it applies to other weak references such as delegate and data source references as well. For those you can often get away with not clearing them if they end up getting deallocated at the same time, but as people are discovering here, in some situations you can't count on that.
