I have a view controller hierarchy and the top-most controller is displayed as a modal and would like to know how to display the navigation bar when using
'UIViewController:presentViewController:viewControllerToPresent:animated:completion'
The docs for 'presentViewController:animated:completion:' note:
'On iPhone and iPod touch, the presented view is always full screen. On iPad, the presentation depends on the value in the modalPresentationStyle property.'
For 'modalPresentationStyle', the docs say:
The presentation style determines how a modally presented view controller is displayed onscreen. On iPhone and iPod touch, modal view controllers are always presented full-screen, but on iPad there are several different presentation options.
Is there way to ensure that the navigation bar is visible below the status bar once the view control displays itself? Should I interpret the doc as, you don't get any options of iPhone/iPod and only on iPad?
Previously, I was using 'UIViewController:presentModalViewController:animated'
which worked fine, but since iOS 5.0, the API has been deprecated so I'm switching over to the new one.
Visually, what I'm looking to do is have the new controller slide in from the bottom of the screen, just like the old API used to do.
[updating with code]:
// My root level view:
UIViewController *vc = [[RootViewController alloc]
initWithNibName:nil
bundle:[NSBundle mainBundle]];
navController = [[UINavigationController alloc] initWithRootViewController:vc];
....
// Within the RootViewController, Second view controller is created and added
// to the hierarchy. It is this view controller that is responsible for
// displaying the DetailView:
SecondTierViewController *t2controller = [[SecondTierViewController alloc]
initWithNibName:nil
bundle:[NSBundle mainBundle]];
[self.navigationController pushViewController:t2controller animated:YES];
// Created by SecondTierViewController
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;
[self.navigationController presentViewController:controller
animated:YES
completion:nil];
It is true that if you present a view controller modally on the iPhone, it will always be presented full screen no matter how you present it on the top view controller of a navigation controller or any other way around. But you can always show the navigation bar with the following workaround way:
Rather than presenting that view controller modally present a navigation controller modally with its root view controller set as the view controller you want:
MyViewController *myViewController = [[MyViewController alloc] initWithNibName:nil bundle:nil];
UINavigationController *navigationController =
[[UINavigationController alloc] initWithRootViewController:myViewController];
//now present this navigation controller modally
[self presentViewController:navigationController
animated:YES
completion:^{
}];
You should see a navigation bar when your view is presented modally.
Swift 5.*
Navigation:
guard let myVC = self.storyboard?.instantiateViewController(withIdentifier: "MyViewController") else { return }
let navController = UINavigationController(rootViewController: myVC)
self.navigationController?.present(navController, animated: true, completion: nil)
Going Back:
self.dismiss(animated: true, completion: nil)
Swift 2.0
Navigation:
let myVC = self.storyboard?.instantiateViewControllerWithIdentifier("MyViewController");
let navController = UINavigationController(rootViewController: myVC!)
self.navigationController?.presentViewController(navController, animated: true, completion: nil)
Going Back:
self.dismissViewControllerAnimated(true, completion: nil)
Can you use:
[self.navigationController pushViewController:controller animated:YES];
Going back (I think):
[self.navigationController popToRootViewControllerAnimated:YES];
I had the same problem on ios7. I called it in selector and it worked on both ios7 and ios8.
[self performSelector: @selector(showMainView) withObject: nil afterDelay: 0.0];
- (void) showMainView {
HomeViewController * homeview = [
[HomeViewController alloc] initWithNibName: @
"HomeViewController"
bundle: nil];
UINavigationController * navcont = [
[UINavigationController alloc] initWithRootViewController: homeview];
navcont.navigationBar.tintColor = [UIColor whiteColor];
navcont.navigationBar.barTintColor = App_Theme_Color;
[navcont.navigationBar
setTitleTextAttributes: @ {
NSForegroundColorAttributeName: [UIColor whiteColor]
}];
navcont.modalPresentationStyle = UIModalPresentationFullScreen;
navcont.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self.navigationController presentViewController: navcont animated: YES completion: ^ {
}];
}
All a [self.navigationController pushViewController:controller animated:YES];
does is animate a transition, and add it to the navigation controller stack, and some other cool navigation bar animation stuffs. If you don't care about the bar animation, then this code should work. The bar does appear on the new controller, and you get an interactive pop gesture!
//Make Controller
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
//Customize presentation
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;
//Present controller
[self presentViewController:controller
animated:YES
completion:nil];
//Add to navigation Controller
[self navigationController].viewControllers = [[self navigationController].viewControllers arrayByAddingObject:controller];
//You can't just [[self navigationController].viewControllers addObject:controller] because viewControllers are for some reason not a mutable array.
Edit: Sorry, presentViewController will fill the full screen. You will need to make a custom transition, with CGAffineTransform.translation or something, animate the controller with the transition, then add it to the navigationController's viewControllers.
Swift 3
let vc0 : ViewController1 = ViewController1()
let vc2: NavigationController1 = NavigationController1(rootViewController: vc0)
self.present(vc2, animated: true, completion: nil)
Swift version : This presents a ViewController which is embedded in a Navigation Controller.
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
// Identify the bundle by means of a class in that bundle.
let storyboard = UIStoryboard(name: "Storyboard", bundle: NSBundle(forClass: SettingsViewController.self))
// Instance of ViewController that is in the storyboard.
let settingViewController = storyboard.instantiateViewControllerWithIdentifier("SettingsVC")
let navController = UINavigationController(rootViewController: settingViewController)
presentViewController(navController, animated: true, completion: nil)
}
I use this code. It's working fine in iOS 8.
MyProfileEditViewController *myprofileEdit=[self.storyboard instantiateViewControllerWithIdentifier:@"myprofileeditSid"];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:myprofileEdit];
[self presentViewController:navigationController animated:YES completion:^{}];
One solution
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil
bundle:[NSBundle mainBundle]];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:controller];
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
navController.modalPresentationStyle = UIModalPresentationCurrentContext;
[self.navigationController presentViewController:navController
animated:YES
completion:nil];
If you didn't set the modalPresentationStyle property (like to UIModalPresentationFormSheet), the navigation bar will be displayed always. To ensure, always do
[[self.navigationController topViewController] presentViewController:vieController
animated:YES
completion:nil];
This will show the navigation bar always.
If you use NavigationController in Swift 2.x
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let targetViewController = storyboard.instantiateViewControllerWithIdentifier("targetViewControllerID") as? TargetViewController
self.navigationController?.pushViewController(targetViewController!, animated: true)
try this
let transition: CATransition = CATransition()
let timeFunc : CAMediaTimingFunction = CAMediaTimingFunction(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.duration = 1
transition.timingFunction = timeFunc
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
self.view.window!.layer.addAnimation(transition, forKey: kCATransition)
self.presentViewController(vc, animated:true, completion:nil)
Success story sharing
(void)presentViewController:(UIViewController *)viewControllerToPresent animated: (BOOL)flag completion:(void (^)(void))completion
'NSInvalidArgumentException', reason: 'Pushing a navigation controller is not supported'
). How can this work?
