    1. COIt could be anywhere in the init code of the view controllers you create there too, that's potentially quite a bit of code to check :) Maybe somebody has a good idea to systematically home in on the problem, I'd be interested in that as well

    2. COdid you use ARC? the "- (void)applicationDidFinishLaunching:(UIApplication *)application " Method is deprecated please use: "- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:"(NSDictionary *)launchOptions

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.
