The title pretty much says it all. I have a ViewController which I present like this:
let communityVC = self.storyboard?.instantiateViewController(withIdentifier: "CommunityVC") as! CommunityViewController
communityVC.hero.modalAnimationType = .zoomSlide(direction: .right)
let addButtonHeroID = "addWishButtonID"
self.addButton.heroID = addButtonHeroID
communityVC.homeButton.heroID = addButtonHeroID
self.present(communityVC, animated: true, completion: nil)
The thing is that insice comunityVC I would like to push another ViewController. Is that somehow possible? I couldnt really find a Swift solution that is working.
You need to present communityVC after embedding the UINavigationController, then you can push the view controller inside communityVC, so you can push ViewController by using navigationController?.pushViewController(vc, animated: true) from communityV
let communityVC = self.storyboard?.instantiateViewController(withIdentifier: "CommunityVC") as! CommunityViewController
let navController = UINavigationController(rootViewController: communityVC)
communityVC.hero.modalAnimationType = .zoomSlide(direction: .right)
let addButtonHeroID = "addWishButtonID"
self.addButton.heroID = addButtonHeroID
communityVC.homeButton.heroID = addButtonHeroID
self.present(navController, animated: true, completion: nil)

How to present UIViewController() inside of UINavigationController ? My controller presenting not fullscreen. I want my app to look like this enter image description here, but it is end up like this enter image description here
I making app without Storyboard(Programmatically)
let customVC = UIViewController()
customVC.view.backgroundColor = .green
customVC.modalPresentationStyle = .fullScreen
let navVC = UINavigationController(rootViewController: customVC)
self.present(navVC, animated: true, completion: nil)
let customVC = DestinationController()
let navVC = UINavigationController(rootViewController: customVC)
// this line overFullScreen
navVC.modalPresentationStyle = .overFullScreen
// for more style
navVC.modalTransitionStyle = .crossDissolve
self.present(navVC, animated: true, completion: nil)
your class where you want to go or present
class DestinationController:UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .red
}
}
From my onboarding viewcontroller i need to transition to my tabBarController which is also a navigationController and i want to make it as a root viewcontroller afterwards.
#objc func willGoToMain(sender: UIButton!) {
let tabBarController = TabBarController()
let navigationController = UINavigationController(rootViewController: tabBarController)
navigationController.isNavigationBarHidden = true
self.present(tabBarController, animated: true, completion: nil)
}
Thread 1: "Application tried to present modally a view controller <MyStarterProject.TabBarController: 0x7f9bd8011400> that has a parent view controller <UINavigationController: 0x7f9bd7022800>
I like to transition it like a modal presentation or cross dissolve. not just to appeared as a rootviewcontroller all of a sudden.
Here's what i'm trying to do and this solves my problem.
#objc func willGoToMain(sender: UIButton!) {
guard let window = UIApplication.shared.keyWindow else {
return
}
let tabbarController = TabBarController()
let navigationController = UINavigationController(rootViewController: tabbarController)
navigationController.isNavigationBarHidden = true
window.rootViewController = navigationController
window.makeKeyAndVisible()
let options: UIView.AnimationOptions = .transitionCrossDissolve
let duration: TimeInterval = 0.3
UIView.transition(with: window, duration: duration, options: options, animations: {}, completion:
{ completed in
// maybe do something on completion here
})
}
Change this:
self.present(tabBarController, animated: true, completion: nil)
with this:
self.present(navigationController, animated: true, completion: nil)
Please try this one.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let mainTabBarController = storyboard.instantiateViewController(identifier: "MainTabBarController")
mainTabBarController.modalPresentationStyle = .fullScreen
self.present(mainTabBarController, animated: true, completion: nil)

I am trying to present NavigationController and select second tab in the completion block. My code is:
let chatViewController = UITabBarController()
let navigationController = UINavigationController(rootViewController: chatViewController)
present(navigationController, animated: true, completion: {
self.visibleViewController = navigationController
self.visibleViewController?.tabBarController?.selectedIndex = 1
})
Second attempt:
let chatViewController = UITabBarController()
let navigationController = UINavigationController(rootViewController: chatViewController)
navigationController.tabBarController?.selectedIndex = 1
present(navigationController, animated: true, completion: {
self.visibleViewController = navigationController
})
In both cases tabBarController is nil. How can I switch to different tab?
You are trying to access UITabBarController of UINavigationController, but you need to access the very first controller from UINavigationController and from there you need to make your UITabBar selected like this way:
func showTabBarControllerr() {
let chatViewController = UITabBarController()
//Note: Make sure you have already added the Controllers in Tabbarcontroller
chatViewController.viewControllers = [DemoOne(), DemoTwo()]
let navigationController = UINavigationController(rootViewController: chatViewController)
present(navigationController, animated: true, completion: {
if let tabBarController = navigationController.viewControllers.first as? UITabBarController {
tabBarController.selectedIndex = 1
}
})
}
Let me know this helps or not!
Instead of calling
present(navigationController, animated: true, completion: { })
in viewDidLoad, try to call it in viewWillAppear or viewDidAppear
Try this (Swift 5):
Set an identifier to your UITabBarController in the Storyboard, something like MainTabBar
Into a function or IBAction, use this code:
let tbc = storyboard?.instantiateViewController(withIdentifier: "MainTabBar") as! UITabBarController
tbc.selectedIndex = 1 // This is the index of your controller
present(tbc, animated: false, completion: nil)
I'm trying to present a view controller and dismiss my current modal view. I saw the answers on StackOverflow, but I don't understand it.
self.dismissViewControllerAnimated(true, completion: {
let vc = self.storyboard?.instantiateViewControllerWithIdentifier("myViewController")
self.presentViewController(vc!, animated: true, completion: nil)
})
Could anyone please tell me, how to do it simply? Thanks
Check your main controller in stack and pop all other view controllers and then present new View Controller.
if let controllers = self.navigationController?.viewControllers {
for vc in controllers {
// Check if the view controller is of MainViewController type
if let myVC = vc as? MainViewController {
self.navigationController?.popToViewController(myVC, animated: false)
}
}
}
Push view controller :
let secondVC = self.storyboard?.instantiateViewController(withIdentifier: "secondVC") as! SecondViewController
self.navigationController?.pushViewController(secondVC, animated: true)
or Present View Controller :
let next = self.storyboard?.instantiateViewController(withIdentifier: "secondVC") as! SecondViewController
self.present(next as UIViewController, animated: true, completion: nil)
You can use this code to Present viewcontroller.
let yourVC = UIStoryboard(name: storyBord, bundle: nil).instantiateViewController(withIdentifier:ID) as! yourViewController
let navController = UINavigationController(rootViewController: yourVC)
self.present(navController, animated: true, completion: {
})
And for dissmissing use this in your presented viewController
self.dismiss(animated: true, completion: {
})
I use this function to push a new viewController:
func goToPasscodeSetupVC() {
let storyboard = UIStoryboard(name: "PassCode", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "passcodeSetupVC") as! PasscodeSetupVC
self.navigationController?.pushViewController(viewController, animated: true)
}
But, when I am on the new viewController, I want to dismiss the previous one so that I could't reach it with a swipe gesture.
You can use this to disable swipe back gesture.
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = false
You can try setViewControllers instead of pushViewController
let storyboard = UIStoryboard(name: "PassCode", bundle: nil)
let viewController = storyboard.instantiateViewController(withIdentifier: "passcodeSetupVC") as! PasscodeSetupVC
self.navigationController?.setViewControllers([viewController], animated: true)
