Then drag in a Container View object into each banner view controller and embed your child view controllers in each banner view controller. Finally in BannerViewController.m replace the … Read more
Suppose, we’re in FirstViewController //Obj-C – (void) presentSecondVC { SecondViewController *vc = [[SecondViewController alloc] init]; [self addChildViewController:vc]; [self didMoveToParentViewController:vc]; } //Swift func presentSecondVC() { let vc = SecondViewController.init() self.addChildViewController(vc) self.didMove(toParentViewController: vc) } Some of you may need to write above method like this, //Obj-C – (void) presentSecondVC { SecondViewController *vc = [[SecondViewController alloc] init]; vc.view.frame … Read more
It sounds like you may be performing the segue in -viewWillAppear: thus generating two -viewWillAppear: messages without 2 corresponding -viewDidAppear messages. Try performing the segue in -viewDidAppear.
Actually it is pretty easy to do. You just need to connect navigation isNavigationBarHidden property with status bar. Objective-C – (BOOL)prefersStatusBarHidden { return self.navigationController.isNavigationBarHidden; } Swift <= 2.3 override func prefersStatusBarHidden() -> Bool { return navigationController?.navigationBarHidden ?? false } Swift 3.0 override var prefersStatusBarHidden: Bool { return navigationController?.isNavigationBarHidden ?? false } And be sure you … Read more

Here’s what the navigation bar looks like before you show the search: And here’s what it looks like afterwards: The two replicant views and the extra UILabel are the problem. I don’t know what they’re doing … Read more
You can create a NSMutableArray from the navigationController’s array of viewcontrollers and insert new viewController before the current one. Then set the viewControllers array without animation and pop back. UIViewController *newVC = …; NSMutableArray *vcs = [NSMutableArray arrayWithArray:self.navigationController.viewControllers]; [vcs insertObject:newVC atIndex:[vcs count]-1]; [self.navigationController setViewControllers:vcs animated:NO]; [self.navigationController popViewControllerAnimated:YES];
Put this code in the view controller you want to hide the navigation bar for. – (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.navigationController setNavigationBarHidden:YES animated:animated]; } And you may also want to stick this in there, depending on your needs: – (void) viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [self.navigationController setNavigationBarHidden:NO animated:animated]; }
iOS 5 introduced two new methods to handle exactly this type of situation. What you’re looking for is -[UIViewController isMovingToParentViewController]. From the docs: isMovingToParentViewController Returns a Boolean value that indicates that the view controller is in the process of being added to a parent. – (BOOL)isMovingToParentViewController Return Value YES if the view controller is appearing … Read more
You can set the property barPosition to UIBarPositionTopAttached another way! Add a delegate to your UINavigationBar. Implement -positionForBar: in the delegate class: – (UIBarPosition)positionForBar:(id<UIBarPositioning>)bar { return UIBarPositionTopAttached; } Your navigation bar’s top must also be anchored to the Top Layout Guide.
Like rmaddy said in the comments you are trying to push a navigation controller. Navigation controllers should be presented (via presentViewController or they can be added as a childViewController) and ViewControllers should be pushed.
