    <p>I have the following code in my <code>AppDelegate</code>:</p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @class PersonalDiarySystemViewController; @interface PersonalDiarySystemAppDelegate : NSObject &lt;UIApplicationDelegate&gt; { UIWindow *window; PersonalDiarySystemViewController *viewController; UINavigationController *navigationController; } @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet PersonalDiarySystemViewController *viewController; @property (nonatomic, retain) UINavigationController *navigationController; @end #import "PersonalDiarySystemAppDelegate.h" #import "PersonalDiarySystemViewController.h" @implementation PersonalDiarySystemAppDelegate @synthesize window; @synthesize viewController; @synthesize navigationController; #pragma mark - #pragma mark Application lifecycle - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. // Set the view controller as the window's root view controller and display. self.window.rootViewController = self.viewController; navigationController = [[UINavigationController alloc] initWithRootViewController:self.window.rootViewController]; navigationController.navigationBar.tintColor = [UIColor colorWithRed:217.0/255 green:33.0/255 blue:0 alpha:1]; navigationController.navigationBarHidden = YES; [self.window addSubview:navigationController.view]; [self.window makeKeyAndVisible]; return YES; } </code></pre> <p>My rootviewcontroller tries to load another viewcontroller into the navigation controllers stack in its <code>viewDidLoad</code> method but for some reason the view is not getting pushed:</p> <pre><code>-(void) viewDidLoad{ lvc = [[LoginViewController alloc] init]; //lvc.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; [lvc setDelegate:self]; //[self presentModalViewController:lvc animated:YES]; [self.navigationController pushViewController:lvc animated:YES]; } </code></pre> <p>I'm getting no errors so not sure whats going on...using <code>presentModalViewController</code> works...so really am confused!!</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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
