    <p>I have an MKMapView, and I'm trying to set the map, so that when you first load the application it goes to a user set location, and if the user hasn't set one, to a default one. The problem is that it always seems to go to 0 latitude, 0 longitude. </p> <pre><code>-(void) viewDidLoad { [worldView setShowsUserLocation:YES]; double longitude = [[NSUserDefaults standardUserDefaults] doubleForKey:WhereamiNewLongPrefKey]; double latitude = [[NSUserDefaults standardUserDefaults] doubleForKey:WhereamiNewLatPrefKey]; CLLocationCoordinate2D savedLoc = CLLocationCoordinate2DMake(latitude, longitude); MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance(savedLoc, 250, 250); NSLog(@"latitude :%f", region.center.latitude); NSLog(@"longitude :%f", region.center.longitude); [worldView setRegion:region animated:YES]; } </code></pre> <p>I've tried setting <code>setShowUserLocation</code> to <code>NO</code>, but that doesn't work. I know it's reading the correct region, because the <code>NSLog</code> is outputing the default latitude, but the map insists on going to somewhere in China...</p> <p>I've also tried setting the region in <code>mapView:didUpdateUserLocation:</code>, but still the same result.</p> <p>What am I doing wrong?</p> <p>EDIT: I added the <code>NSLog</code> to output the longitude as well. The output is:</p> <pre><code>2012-11-14 09:50:30.699 Whereami[34256:13d03] latitude :20.516700 2012-11-14 09:50:30.699 Whereami[34256:13d03] longitude :99.900000 </code></pre>

    1. COChange the NSLog to print out both latitude and longitude and tell us what it prints. It's possible that your longitude is wrong. Is it positive? That would mean it is in the eastern hemisphere.

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.
