    <p>Here's how I recommend doing it: </p> <p>Store lat/long in a dictionary and fire them off as strings bundled in a notification. Setup an observer in the application delegate and have the callback function store the lat/long in class properties of the application delegate and/or store them in the application defaults. </p> <p>In your class where you acquire the coordinates:</p> <pre><code>- (void)locationUpdate:(CLLocation *)location { NSString *locationString, *locLat, *locLong; locationString = [location description]; locLat = [NSString stringWithFormat:@"%lf", location.coordinate.latitude]; locLong = [NSString stringWithFormat:@"%lf", location.coordinate.longitude]; NSDictionary *locationDictionary = [NSDictionary dictionaryWithObjectsAndKeys:locationString, @"description", locLat, @"latitude", locLong, @"longitude", nil]; [[NSNotificationCenter defaultCenter] postNotificationName:@"updateSearchLocation" object:self userInfo:locationDictionary]; } </code></pre> <p>In your application delegate class:</p> <pre><code>- (void)applicationDidFinishLaunching:(UIApplication *)application { // Listen for search coordinates broadcast [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(setCoordinates:) name:@"updateSearchLocation" object:nil]; } - (void)setCoordinates:(id)sender { self.latitude = [[sender userInfo] objectForKey:@"latitude"]; self.longitude = [[sender userInfo] objectForKey:@"longitude"]; NSLog(@"location = %@", [[sender userInfo] objectForKey:@"description"]); } </code></pre> <p>Dont forget to setup the class properties in the application delegate header file as NSString. You can then access the coordinates by calling directly from the application delegate: </p> <pre><code>YourAppDelegateClassName *appDelegate = [[UIApplication sharedApplication] delegate]; NSLog(@"lat = %@, long = %@", appDelegate.latitude, appDelegate.longitude); </code></pre> <p>Or you can access them anywhere from the user defaults:</p> <pre><code>[[NSUserDefaults standardUserDefaults] objectForKey:@"latitude"]; [[NSUserDefaults standardUserDefaults] objectForKey:@"longitude"]; </code></pre> <p>I hope that helps.</p>

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.
