    1. COThis answer is exactly what I have been looking for. One question: In Apple's reference example code (http://developer.apple.com/library/ios/ipad/#samplecode/MultipleDetailViews/Listings/Classes_RootViewController_m.html), they handle the UiSplitviewcontroller delegate in the root view controller. You handle it in the detailed controller instead. Is there a reason for one way or the other?

    2. COThe controller that becomes delegate is up to you. If you feel that the `detailViewController` is going to *command* the `rootViewController` that is completely fine :). Although in that case you probably want to rename you variables to something that fits your design (e.g. `listViewController` and `mainViewController` for `rootViewController` and `detailedViewController` respectively)

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
