I create a view controller vc in storyboard and place a View1 on it and add all constraint to it. Now I want to add a vc as a subview. I use this code :
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("LeftMenuListIdentifier")
self.view.addSubview(vc.view)
vc controller's add as subview to my current controller but it does not show any subview of vc controller'view means View1.
If I push vc controller to my current view controller then it shows View1.
self.navigationController?.pushViewController(vc, animated: true)
Please suggest what should I do . I want to add a view controller from storyboard as a subview.
Kindly Follow below steps for resolve your issue.
First Create UIViewController object.
after that Add object as a childviewcontroller as Like ( self.addChildViewController("Your Controller Object"))
After that add controller on self.view as add subview.( `self.view.addSubview("Your Controller Object"))
i think it will working
you don't need to push your vc, just add it to current viewcontroller using addChildViewController(vc);, this link may help you

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.
How to dismiss any View Controller without using Storyboard ? and do I have to use UINavigationController to achieve this ? if not how then ?
if someone is still struggling to dissmiss on swipe (left,right,bottom,top)
i came across a very elegant and decent cocapod panslip
with a very simple usage
just call this method in viewDidLoad()
For viewController embedded in navigation Controller
let viewControllerVC = self.navigationController
viewControllerVC!.ps.enable(slipDirection: .leftToRight){
//anything you want to do after dissming
}
For Simple View Controller
let viewControllerVC = self
viewControllerVC!.ps.enable(slipDirection: .leftToRight){
//anything you want to do after dissming
}
For TableView embedded in View Controller
let viewControllerVC = self.YourTableview.parentContainerViewController()
viewControllerVC!.ps.enable(slipDirection: .leftToRight){
//anything you want to do after dissminn
}
The way to dismiss a view controller is to call a dismiss method on the presenting view controller. If you presented your child controller from a parent by calling self.present(_:animated:) then you can call self.dismiss(animated:). If you used a navigationController and called navigationController.push(_:animated:) then you need to tell the navigation controller to dismiss with navigationController.popViewController(animated:)
Method names might not be exact, but you should be able to figure it our with autocomplete.
If you want to swipe right is not a dismiss, but I think that what you want it to embed the UIViewController inside a UINavigationController.
For example:
if let vc = UIStoryboard(name: "YourStoryboard", bundle: nil).instantiateViewController(withIdentifier: "YourViewController") as? YourViewController {
let navigation = UINavigationController(rootViewController: vc)
navigationController?.pushViewController(vc, animated: true)
}
I have ViewController created using StoryBoards and I set it's class to be MyViewController.
MyViewController is class that inherits from UIViewController and have some UI elements. One of this elements is UIButton. I can programmatically add actions to this button as addTarget.
I want to to change view in NavigationController when button is clicked
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let newViewController = storyboard.instantiateViewController(withIdentifier: "newViewComtroller")
navigationController.pushViewController(newViewController, animated: true)
But nothing happens - why?
Check in your storyboard if your view controller has an embeded Navigation Controller. If not, you can click in your view controller, go to "Editor" on XCode's menu, "Embed in", and choose "Navigation Controller". After that, your view controller will be associated with a navigation controller, and you should be able to use the method "pushViewController" properly.
When I start the app my initial view is MainViewController.
Then on button click I move to AnotherViewController.
performSegueWithIdentifier("myFirstSegue", sender: self)
On AnotherViewController I have a button that should return me back to MainViewController but I don't want to instantiate new but to use existing instance.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
var story = storyboard.instantiateViewControllerWithIdentifier("MainViewController") as! ViewController
let navigationController = UINavigationController(rootViewController: story)
self.showViewController(navigationController, sender: nil)
With this code I create new so I lost data that I stored on that view.
How can I get existing instance and just move to it?
UPDATE
To explain issue better if on first view I have UISwitch and move to another ViewController and then get back to first I want to UISwitch stay same not "reset".
if you are using a navigation controller, doing this will pop to your previous controller. navigationController.popViewControllerAnimated(true)
you can use this one
self.dismissViewControllerAnimated(false, completion: nil);
Navigation controller maintains the stack of viewcontrollers. just pop your viewcontroller and you will be back to your previous view controller.
navigationController.popViewControllerAnimated(true)
or use unwind segue from storyboard.
What are Unwind segues for and how do you use them?
I was wondering if i could make some sort of a segue between these 2 views in a Xib file.
the main View is loaded into a scrollview in the storyboard.
.
(so if ik click Bewerken(edit) i would get pushed to the view controller on the right)
Thanks!
I would suggest changing this to a Container View inside the storyboard instead of a separated Xib. You can add and position/size UIContainerView as a subview and add a"Storyboard Embed Segue to attach another ViewController. This is what it will look like in IB/Storyboard:
During runtime, the blue UIView (or the embedded UIViewController if you like) will be embedded in the hosting UIView as a subview:
If you change your implementation to this, you are in the beautiful segue world where you can just drag-and-drop segues :)
You could do 2 things:
1 - Wrap the main view in a Navigation Controller so you can do the following:
#IBAction func loadEditController(sender:UIButton){
let editController = RegisterController(nibName:"RegisterXIB", bundle:nil)
navigationController?.pushViewController(editController, animated: true)
}
2 - Present the Edit Controller over the current context and animate it yourself
#IBAction func loadEditController(sender:UIButton){
let editController = RegisterController(nibName:"RegisterXIB", bundle:nil)
editController.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
presentViewController(editController, animated: false, completion: nil)
//Move it offscreen and the animate it here
}
