    <p>When my app launches, I check for reachability because I need an immediate internet connection. My problem, though, is that it appears there's no immediate confirmation for the <code>NetworkStatus</code>, which means right after the Reachability is setup, I check whether there's a connection, and it returns that there isn't, regardless of whether I am in fact on WiFi/3G, or have turned the radio off.</p> <p>I can confirm that I am in fact getting an Internet connection, because instantly after applicationDidFinishLaunching, there's a notification which then logs "ReachableViaWiFi"..</p> <p>What am I doing wrong? Why is it not confirming a valid Internet connection right away?</p> <pre><code>- (void)applicationDidFinishLaunching:(UIApplication *)application { NetworkStatus netStatus = [hostReach currentReachabilityStatus]; if (netStatus == NotReachable) { ErrorViewController *errorViewController = [[ErrorViewController alloc] initWithNibName:@"ErrorView" bundle:[NSBundle mainBundle]]; [tabBarController.view removeFromSuperview]; [window addSubview:[errorViewController view]]; return; } } -(void)setupReachability { [[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(reachabilityChanged:) name:kReachabilityChangedNotification object: nil]; hostReach = [[Reachability reachabilityWithHostName:@"www.google.com"] retain]; [hostReach startNotifier]; } -(void)reachabilityChanged:(NSNotification *)notification { Reachability* curReach = [notification object]; NSParameterAssert([curReach isKindOfClass: [Reachability class]]); NetworkStatus netStatus = [curReach currentReachabilityStatus]; BOOL connectionRequired = [curReach connectionRequired]; switch (netStatus) { case NotReachable: { [[NSUserDefaults standardUserDefaults] setInteger:kNOTREACHABLE forKey:kREACHABILITYSTATUS]; NSLog(@"NotReachable"); connectionRequired = NO; break; } case ReachableViaWWAN: { [[NSUserDefaults standardUserDefaults] setInteger:kREACHABLEVIAWWAN forKey:kREACHABILITYSTATUS]; NSLog(@"ReachableViaWWAN"); break; } case ReachableViaWiFi: { [[NSUserDefaults standardUserDefaults] setInteger:kNOTREACHABLE forKey:kREACHABILITYSTATUS]; NSLog(@"ReachableViaWiFi"); break; } } } </code></pre>

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.
