I have navigationBar with this side menu
I and I want add Button when I pressed go to root view controller
I tried using all of this
presentingViewController!.dismissViewControllerAnimated(true, completion: nil)
self.navigationController!.popToRootViewControllerAnimated(false)
let viewControllers: [UIViewController] = self.navigationController!.viewControllers as [UIViewController];
self.navigationController!.popToViewController(viewControllers[viewControllers.count ], animated: true);
please if anyone can try download the example and tell me what the wrong and what I should do
this is my main storybord
I want to pop this viewcontrller or any numbers of viewControllrs above it using sideMenu class
side menuclass is table, so I use this method didSelectRowAtIndexPath
some cell if user press it, it should pop all views above main views
this way work well with push, but pop No

I have a button on a view controller and by clicking that button a view controller appears as a popup. That popup has a tableview and whenever I click on the tableview row I want it to navigate to different view controller. But I think it is not as simple as using this code.
let vc = storyboard?instantiateViewController(identifier: "controller") as! Controller
self.navigationController.pushViewController(popupView, animated: true, completion: nil)
Is there a way to open a view controller from popup view?
It's easier to show you a drawing and then explain.
Dashboard Storyboard
I have 2 separate UIViewControllers (i've included just one in the drawing, the other is irrelevant) embedded in container view called ContainerViewController.
Post Storyboard
NewPostViewController shows a UIButton that presents TextPostViewController. As you can see, all of them are embedded in UINavigationControllers. Now, once the completion block of the new post is being called, I have to present the ContainerViewController and it needs to handle it's own logic. The problem is that it's embedded in UINavigationController and once I present it, the UITaBbar is hidden.
I tried to do this:
self.performSegue(withIdentifier: "TextPostToNavContainerVC", sender: nil)
The transition is successful but I'm losing the UITabBar, even though in the DashboardViewController and the ContainerViewController I called:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
tabBarController?.tabBar.isHidden = false
}
What am I doing wrong or is there are better way to do that?
You should instantiate the tab bar controller. not the view controller.
Imagine you're putting a initial view controller ahead of your tab bar controller. Making your tab bar not being pushed
If I undestand it correctly.
You are doing this
Segue connect to a view controller
But you should actually do this Segue connected to a tab bar controller
You can try to add it as a child to control it's frame like this
let textPost = self.storyboard?.instantiateViewController(withIdentifier: "containerID") as! TextPostToNavContainerVC
textPost.view.frame = CGRect(x:20,y:0,width:self.view.frame.width,height:self.view.frame.height-50)
self.view.addSubview(nvc.view)
self.addChildViewController(textPost)
textPost.didMove(toParentViewController: self)
Im building an app in swift for macOS, and I have a button on my initial view controller that I want to display a different view controller. I ctrl dragged from that button to the new view controller, and all of the segue options display the new view controller as a new window, rather that replacing the initial view. How can I make this button transition view controllers similar to how it works in iOS apps?
You can first make your segue to the 2nd view controller and then create an IBAction from your button where you call
self.dismiss(animated: true, completion: {})
within it. By doing this your initial view controller will no longer exist.
More detailed:
Segue from your button to the second view controller (ctrl drag)
Make an IBAction by ctrl drag from your button to the view controllers code
Put this into your IBAction:
self.dismiss(animated: true, completion: {})
Now it should look something like this:
#IBAction func dismissView(_ sender: Any) {
self.dismiss(animated: true, completion: {})
}
By clicking on your button your application go to the next view controller and the initial view controller will be dismissed.
I have a bit of an odd problem. Note that everything is done programmatically, so please no storyboard suggestions. Here's the setup:
I have a Master-Detail view layout, where the Detail view is a map. The Master-view's table is filled with cells that represent annotation points on the map. When you tap on a cell, it focuses on that annotation on the map and opens a custom annotation view using a popover. Likewise, when you tap the annotation itself, the same popover opens. So far, so good.
Now, inside the popover and inside each cell there is an a button which, when pressed, should open a new view that fills the whole screen. The view would have information specific to its corresponding annotation.
Here is how I am trying to do it:
Class that has the map (MyDetailViewController)
public func openNewViewController(){
self.presentViewController(NewViewController(), animated: true, completion: nil)
}
Function call for cell button and popover button
func btnPressed(sender: AnyObject){
var dvc = MyDetailViewController()
dvc.openNewViewController()
}
When either button gets tapped, I get the same error:
Warning: Attempt to present NewViewController on DetailViewController whose view is not in the window hierarchy!
So, what does it mean that DetailViewController is not in the window hierarchy..? It must be since I see it, no?
Any idea how to fix this issue? Thanks in advance!
Your function openNewViewController() is doing nothing!
See the code
self.presentViewController(openNewViewController()) , animated : true , completion: nil)
is pointing to itself.
Instead try this :
public func openNewViewController(){
var newController = UIViewController() // or any other view you wish to instantiate
self.presentViewController(newController, animated: true, completion: nil)
}
I created a project with six View over to the View menu that has a cancel button. if you are in one of the View from 2 to 6 and I open the menu, and then I press cancels hypothetically I return to View 1, how can I change the code so as to leave the current view? Also insert the code ....
#IBAction func unwindToMainViewController (sender: UIStoryboardSegue){
self.dismissViewControllerAnimated(true, completion: nil)
}
Thanks for aid.
UINavigationController has a popToRootViewControllerAnimated method to roll back to the root view controller.
If your view 1 is also the root view controller, and you are using a navigation controller, then you can use the following line of code:
self.navigationController?.popToRootViewControllerAnimated(true)
