title: TableView date section titles
body: <p>My app is something like a log book. I keep an evidence of events that happen in a day. Basically, I have an Entity (displayed on a tableview)  with a "date" attribute. When I save a new event, the current date is stored, using [NSDate date]. How do I get to organize the tableview so all the events will be sorted by day and displayed as such? Any hints will be appreciated!</p>
