    <p>I know this subject has been discussed several times, but I cannot figure out what is causing this error message. I've been stuck here for a couple weeks now and its driving me crazy. The first part of the method sets up a match for 2-4 players. Once a match is found, it tries to add 3 and 4 players within a certain limit. Right now, the limit is just set to 3 seconds, but I envision it being much larger once it is ready for release.</p> <p>I know this is a memory error somewhere in the matchmakerViewController code. When I comment out the code changing the scene, I still get the error. Can you show me what I've done wrong and how to fix it?</p> <pre><code>-(void)matchmakerViewController:(GKMatchmakerViewController *)viewController didFindMatch:(GKMatch *)match { NSLog(@"IN matchmakerViewController!");

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.
