Advanced cache - what happens to deleted posts?


in the chapter, we check to see if the new call to the forum returns new posts. we then have ListViewController add them in with row animation.

I tested by adding a new post. It did add to the table with animation, but when I went to delete my post. It still shows up in the Nerdfeed application. The cached version has the post. When clicking on it, I of course get an error that the link is invalid.

why was this scenario not accounted for? it seem when we get item delta, we should really be getting a list of the differences, both positive and negative


A great deal of these applications have some rough edges to be ironed out if they were production code. We didn’t think people would like having to spend time crossing every t and dotting every i in a tutorial application - it’d be better spent learning new concepts.
