    <p>I am new to objective-c and I am currently working on an iOS App. I have a Button i call SettingsButton, that is inside a custom UIView Object. When I press on this Button the Touch Up Inside handler of the FileOwner "ViewController.m" is called, which later shall push a ViewController on the NavigationController. But the Application crashes with SIGABRT or EXC_BAD_ACCESS. This is occurring since I inserted the code with the NavigationController in AppDelegate.m Any ideas?</p> <p><strong>AppDelegate.m:</strong></p> <pre><code>- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. UIViewController *vc; if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { vc = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil]; } else { vc = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil]; } UINavigationController* navController = [[UINavigationController alloc] initWithRootViewController:vc]; navController.navigationBarHidden = true; [self.window addSubview:navController.view]; [self.window makeKeyAndVisible]; return YES; } </code></pre> <p><strong>ViewController.m:</strong></p> <pre><code>- (IBAction)SettingsPressed:(id)sender { NSLog(@"SettingsPressed!"); } </code></pre> <p>To make clear: My intention is only to change view when pressing the SettingsButton and having a Back-Button to return back. But the App already crashes with empty Eventhandler.</p> <p><strong>Errormessage</strong> when sigabrt occurs:</p> <pre><code>Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString SettingsPressed:]: unrecognized selector sent to instance 0x7a06fc0' </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.
