    <p>I had both a map controller object and a location manager object instantiated in my app delegate.</p> <pre><code>mapController = [[[MapController alloc] initWithFrame:CGRectMake(0, 0, 0, 0)] retain]; [self restartLocationManager]; </code></pre> <p>However, the location manager purpose property is not set until the location manager is instantiated in this code:</p> <pre><code>- (void) restartLocationManager { if (locationManager) [locationManager release]; locationManager = [[[CLLocationManager alloc] init] retain]; locationManager.purpose = NSLocalizedString(@"Location Service Purpose", nil); locationManager.distanceFilter = kCLDistanceFilterNone; locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; [locationManager startUpdatingLocation]; } </code></pre> <p>So this was a clue that something in the initialization of the map was triggering the first alert. </p> <p>Because I declined to turn location services on in the first alert, the map controller initialized and saw a need to show the alert. The map controller initialization is this (it is part of a singleton, and needs some cleanup in that regard, but ignoring that...):</p> <pre><code>- (id) initWithFrame:(CGRect)aFrame { @synchronized(self) { if (!theMap) { if (!self) self = [super init]; theMap = [[[MKMapView alloc] initWithFrame:aFrame] retain]; theMap.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; theMap.showsUserLocation = YES; theMap.delegate = self; } return self; } </code></pre> <p>Stepping through the code, I saw the second alert show up when the <code>showUserLocation</code> line was executed. I'll have to do a little more testing to narrow it down exactly, but I think I'm on the right track now. </p>

    1. COI'm having a similar problem, but I can't for the life of me figure out what's triggering the alert. I don't turn on significant change monitoring unless location services have been authorized for the app. Any tips for me? Honestly, the alert seems quite random.

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.
