I did this. -(void)viewWillDisappear:(BOOL)animated{ [super viewWillDisappear:animated]; [self.view setAlpha:0]; } Do not forget re set alpha when come back. – (void) viewWillAppear:(BOOL)animated{ [super viewWillAppear:animated]; [self.view setAlpha:1]; }
Once you know it, it’s fairly simple: self.navigationController.navigationBar.tintColor = [UIColor blueColor]; self.navigationController.navigationBar.alpha = 0.7f; self.navigationController.navigationBar.translucent = YES; The translucent property seems only to determine wether the main view should be visible under the navigation bar, and resizes the view appropiately.
Another option that I wrote: ECSlidingViewController It has support for orientation changes like Facebook and sliding to the left like Path. Video demo: http://vimeo.com/35959384 Code: https://github.com/edgecase/ECSlidingViewController
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
Since the destination view controller is actually the navigation controller, try accessing the root view like so: UINavigationController *navController = [segue destinationViewController]; ShowItemsTableViewController *SITViewController = (ShowItemsTableViewController *)([navController viewControllers][0]); [SITViewController setItems:[self itemsFromCoreData]];
I know this is an old question but this IS possible, despite of what the “right” answer says. Since this was the first result when I was looking for this I decided to elaborate: This is how you do it: You need to add a property to the View Controller from where you want to … Read more
Use the tabBarController:shouldSelectViewController: method of the UITabBarControllerDelegate protocol. – (BOOL)tabBarController:(UITabBarController *)tabBarController shouldSelectViewController:(UIViewController *)viewController { return viewController != tabBarController.selectedViewController; } Don’t forget to set the delegate of the tab bar controller to the object that actually implements this delegate method.
UPDATE 8/3/20: I posted this in 2016. A number of people have stated this no longer works so please use at your own risk. I am not working in iOS at the moment so I do not have an update handy. Best of luck! Here is one way to do it: override func viewDidAppear(_ animated: … Read more
I know this is old but for anyone else who might be facing similar problems. Here is the approach I used. First I register a UINavigationControllerDelegate to my navigation controller. The delegate needs to implement. Objective-C – (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated Swift func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) So the implementation would … Read more
