I have a UIViewController that contains a UITabBar. I want to push a new UIViewController that covers the current context (so during the animation it shows the new UIViewController covering the UITabBar). How can I do this?
I have tried using the following to push the view but this is not pushed over the UITabBar.
let vc = ViewController2()
vc.modalPresentationStyle = .overFullScreen
navigationController?.pushViewController(vc, animated: true)
I also thought that maybe I could just hide the UITabBar on ViewController2's viewWillAppear and show it on its viewWilDisappear; however, this just makes the UITabBar appear halfway through the dismissal (it looks really bad if you slowly slide to dismiss the view).
In storyboard, go to the UIViewController you are going to push.
Go to attributes inspector and check "Hide Bottom Bar on Push"
This can also be done programmatically:
let vc = viewController1()
vc.hidesBottomBarWhenPushed = true
navigationController?.pushViewController(vc, animated: true)
Hope it helps!
You must use presentViewController, not push.

Can someone help me with this? :(
The navigation bar is not appearing. This is presented by a rootViewController.
You have not posted any code still guessing.
Just taking UINavigationController in storyboad doesn't means that it will appear by default.
You are just presenting view controller. You need to embed in navigation controller or give storyboard identifier to navigation controller and present that.
Example :
let yourviewController = self.storyboard?.instantiateViewController(withIdentifier: "yourVCIdentifer")
let nav = UINavigationController(rootViewController: yourviewController)
self.present(nav, animated: true, completion: nil)
I have navigationController embedded VC(Viewcontroller) in storyboard 1 which is connected to storyboard reference of storyboard 2.
Now, I have VC2 which is again NavController Embedded in storyboard 2.
I am performing the following code :
let storyboard = UIStoryboard(name: "Settings", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "setEdit") as? EditProfile
navigationController?.pushViewController(vc!, animated: true)
settings is storyboard 2, setEdit is ID from navigationController of the destination VC.
When I execute this code, It doesnt perform the presentation of new controller. Also, I have a custom segue class that transitions VCs from Right to Left.
when I use :
present(vc!, animated: true, completion: nil)
It just pushes the VC from bottom to top.
Now I am totally out of Ideas.
My query is:
How can I exactly implement custom segue from one storyboard to another, having navigation bar at the top.
When you use UINavigationController the transition is showed as you said from right to left (push), when you present a view controller modally the presentation style and the transition style are different. Now you cannot connect two navigation controllers, so I suggest to connect directly the controller in the settings storyboard without embedding it in another navigation controller. In settings storyboard you have to set your EditProfileVC as initial view controller and check its identifier and then you can push it from your first storyboard.
I am trying to display a fix navigation bar for my UiTableViewController, I have a first ViewController and when I click on it, this will open my UITableViewController Here is the code of the click :
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("MyTableViewController") as! MyTableViewController
vc.myObject = object // I pass some data
presentViewController(vc, animated: true, completion: nil)
the UItableView is correctly display but not navigation bar appear, if I add one, the navigation bar scroll with the table view and I don't want this behavior.
I tried this without success :
Go to the Editor menu, and click on the Embed In submenu, and choose
Navigation Controller
And tried to change some settings here :
Actually, in your case you want to show navigation and for navigation you have to push your view controller to a UINavigationController thats why the solution is :
let vc = storyboard.instantiateViewControllerWithIdentifier("MyTableViewController") as! MyTableViewController
vc.myObject = object // I pass some data
self.navigationController?.pushViewController(vc, animated: true)
presentViewController offers a mechanism to display a modal view controller; i.e., a view controller that will take full control of your UI by being superimposed on top of a parent controller & establish a parent child relation b/w presenting & presented view controllers.
where as
pushViewController offers a much more flexible navigation process where you can push & pop a new controller to UINavigationController, so to go back to the previous one, in a ordered way. Imagine that controllers in a navigation controller will just build a sequence from left to right like building a stack of view controllers stacking upon each other.
Do it this way:
let vc = storyboard.instantiateViewControllerWithIdentifier("MyTableViewController") as! MyTableViewController
vc.myObject = object // I pass some data
self.navigationController?.pushViewController(vc, animated: true)
I want to use a third-party library which implements a nice tabbar controller. But it does all the work programmatically, basically all it does is create two uiviewcontrollers and add them to a tabbarcontroller, and then instantiate an uinavigationcontroller with the tabbarcontroller. In the last step, it assigns the uinavigationcontroller to the rootviewcontroller of the window like the following:
self.window?.rootViewController = getNavigationController()
But I want to use this navigationcontroller in a place other than the rootviewcontroller of the window, say like I want to push from another view and goes to this navigationcontroller. How can I achieve that?
You can present it modally over your current navigation controller from your current viewcontroller
let vc = myNavigationControllerWithTabBarControllerInside() //change this to your navigation controller
self.navigationController.presentViewController(vc, animated: true, completion: nil)
Please verify, for your self.navigationController to not be nil. otherwise, use
self.presentViewController(vc, animated: true, completion: nil)
I have a view controller VC1 that is presented modally over full screen from some other VC0. In my storyboard I have a modal segue from VC1 to VC2 also presenting over full screen. When in my app I can plainly see VC2 over VC1 over VC0, because some parts of their views are transparent. Perfect.
However, I'm going to reuse VC2 many times so I don't want to have a segue to it for each controller in my storyboard, so I want to accomplish this same thing programmatically. However, when I call presentViewController:animated:completion in VC1 to present VC2, the view of VC1 disappears when the modal transition is complete. When VC2 is dismissed, the view of VC1 reappears when the transition animation is complete.
How can I get the same effect programmatically as when I'm using the storyboard segue?
let newView = self.storyboard!.instantiateViewControllerWithIdentifier("NewViewController") as! NewViewController
newView.modalPresentationStyle = UIModalPresentationStyle.OverFullScreen
self.presentViewController(newView, animated: true, completion: nil)
You can only present on a visible controller, which is usually the rootViewController. But when there is a modally-presented controller, it covers the root controller, so you can't use that. But you can present on the modal, which is accessed though rootViewController.prsentedViewController. Here's some code:
let rootVC = window?.rootViewController
let presentingVC = (rootVC?.presentedViewController ?? rootVC)
presentingVC?.present(myController, animated: true, completion: nil)
You don't need to change the modalPresentationStyle.
You need to set the modalPresentationStyle property of the presented controller to UIModalPresentationOverFullScreen. Set that property just before you call presentViewController:animated:completion.
