POHow can i handle UIInterfaceOrientationPortraitUpsideDown for UINavigationController in iPhone iOS6
text
Body
copied!<p>I know that: By default, an app and a view controller’s supported interface orientations are set to UIInterfaceOrientationMaskAll for the iPad idiom and UIInterfaceOrientationMaskAllButUpsideDown for the iPhone idiom. So when I created a new project with Single View Application template, to perform all orientation in iPhone i add two method below to ViewController.m. And it work!</p> <pre><code>- (NSUInteger)supportedInterfaceOrientations{ return UIInterfaceOrientationMaskAll; } - (BOOL)shouldAutorotate { return YES; } </code></pre> <p>Then i changed some codes in method below of AppDelegate.m to change the root view of application from UIViewController to UINavigationController</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. if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) { self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil]; } else { self.viewController = [[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil]; } if(myNavigationController == nil) myNavigationController = [[UINavigationController alloc]initWithRootViewController:self.viewController]; self.window.rootViewController = self.myNavigationController; [self.window makeKeyAndVisible]; return YES; } </code></pre> <p>After that, i can't handle the UIInterfaceOrientationPortraitUpsideDown in iPhone iOS6 simulator. How can i resolve that? I tried to search a bit of code in older topic but it still not work. </p>
