How do you dismiss the GKTurnBasedMatchmakerViewController once a match is created? The available delegates seems to be only for when there is an error. There used to be one called didFind, but since its deprecated, I am struggling to figure out how to dismiss it once match is created or when player Taps on an existing match.
receivedTurnEventFor is the only follow up call and it has no reference to the match maker view controller.
I am loading GKTurnBasedMatchmakerViewController on an SKView via
let viewController = self.view?.window?.rootViewController
let vc = GKTurnBasedMatchmakerViewController(matchRequest: r)
vc.turnBasedMatchmakerDelegate = self
viewController?.present(vc, animated: true, completion: {
print("launched GKTurnBasedMatchmakerViewController")
})
Just add
self.presentedViewController?.dismiss(animated: true, completion: nil)
in player(_:receivedTurnEventFor:didBecomeActive:)

I am presenting a GKGameCenterViewController in an SKScene that inherits from the following protocol.
protocol GameCenter {}
extension GameCenter where Self: SKScene {
func goToLeaderboard() {
let vc = GKGameCenterViewController()
vc.gameCenterDelegate = GameViewController()
vc.viewState = .leaderboards
vc.leaderboardIdentifier = "leaderboard"
view?.window?.rootViewController?.present(vc, animated: true, completion: nil)
}
}
While the GKGameCenterViewController shows up perfect, when I try to dismiss by clicking the X in the top right corner, nothing happens. I assume this is because the reference to my original GameViewController has been deallocated. How can I get this dismissal to work?
According to Apple's Documentation:
Your delegate should dismiss the Game Center view controller. If your game paused any gameplay or other activities, it can restart those services in this method.
This means you need to implement the gameCenterViewControllerDidFinish method in your delegate and dismiss the gameCenterViewController yourself.
You should have something like this in your GameViewController()
func gameCenterViewControllerDidFinish(_ gameCenterViewController: GKGameCenterViewController) {
gameCenterViewController.dismiss(animated: true, completion: nil)
}
In order to present the GKGameCenterViewController on a SKScene, I needed to find the currently displayed UIViewController reference and set this as the delegate. Here is the code I used and it works:
protocol GameCenter {}
extension GameCenter where Self: SKScene {
func goToLeaderboard() {
var currentViewController:UIViewController=UIApplication.shared.keyWindow!.rootViewController!
let vc = GKGameCenterViewController()
vc.gameCenterDelegate = currentViewController as! GKGameCenterControllerDelegate
vc.viewState = .leaderboards
vc.leaderboardIdentifier = "leaderboard"
currentViewController.present(vc, animated: true, completion: nil)
}
}
I am presenting a view controller inside the ParentViewController:
let item = getCurrentItem()
let presentViewController = viewController as! TestViewController
presentViewController.id = item.id
presentViewController.dismissController { // my custom delegate to inform the parent vc
self.dismiss(animated: true, completion: nil) // presenting view controller is closing then viewWillAppear will be triggered
}
self.present(presentViewController, animated: true, completion: nil)
But when dismiss is called, the ParentViewController's global arrays and variables are back to their initial values.
class ParentViewController {
// MARK: - Stored Properties
private let refreshControl = UIRefreshControl()
private var items = [String:[Item]]()
private var screenLoaded: Bool = false
// MARK: - Controller Lifecycle
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
// after dismiss is called viewWillAppear gets hit but the "screenLoaded" is always false
if !screenLoaded {
screenLoaded = true
}
// items is initialised as well
}
private func openPopover() {
let item = getCurrentItem()
let presentViewController = viewController as! TestViewController
presentViewController.id = item.id
presentViewController.dismissController { // my custom delegate to inform the parent vc
self.dismiss(animated: true, completion: nil) // presenting view controller is closing then viewWillAppear will be triggered
}
self.present(presentViewController, animated: true, completion: nil)
}
}
How can I keep the parent view controller's original state after the dismiss is called?
After hours of digging Apple's documentations finally I found the following solution and it works for me. Hope it helps someone in the future.
[https://developer.apple.com/documentation/uikit/uimodalpresentationstyle/overcurrentcontext][1]
presentViewController.modalPresentationStyle = .overCurrentContext
Also, if there is a tabbar, the bottom of the child view controller will be under it if you set the presentation style to overCurrentContext. The workaround is to present the child view controller from the window's rootViewController.
sender.view.window?.rootViewController?.present(viewController, animated: true, completion: nil)
Now when the dismiss is called viewWillAppear is not triggered and I can keep the parent view controller's data and it's state.
My Scenario, I have three ViewControllers, those ViewControllers First, Second, Third. Here, First ViewController UIButton click to present model second ViewController and then Second ViewController UIButton click to present model Third ViewController. I need to Implement the Second ViewController button click to dismiss current ViewController after presenting Third ViewController because once I close Third ViewController I need to show First ViewController. How to Achieve this?
NOTE: I am having NavigationController for Third ViewController also I am using Storyboard.
Here's my code:
#IBAction func ClickThirdVC(_ sender: Any) {
if let VC_Third = self.storyboard?.instantiateViewController(withIdentifier: "thirdviewcontroller") as? ThirdvViewController {
weak var pvc = self.presentingViewController
VC_B.modalTransitionStyle = .crossDissolve
let navController = UINavigationController(rootViewController: VC_B)
self.dismiss(animated: true, completion: {
pvc?.present(navController, animated: true, completion: nil)
})
}
}
You can try to dismiss self after presenting the third UIViewController, in the completion handler of the present function .
secondVC?.present(navController, animated: true) {
self.dismiss(animated: false, completion: nil) //dismiss self after presenting the third.
}
I've created a popover inside my MainViewController when some button its touched using the UIPopoverPresentationController and set like it's delegate like it's showed in the WWDC 2014, in the following way :
MainViewController.swift
class MainViewController : UIViewController, UIPopoverPresentationControllerDelegate {
#IBAction func showPopover(sender: AnyObject) {
var popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("PopOverViewController") as UIViewController
popoverContent.modalPresentationStyle = UIModalPresentationStyle.Popover
var popover = popoverContent.popoverPresentationController
popoverContent.preferredContentSize = CGSizeMake(250, 419)
popover!.delegate = self
popover!.sourceView = self.view
popover!.sourceRect = CGRectMake(180,85,0,0)
self.presentViewController(popoverContent, animated: true, completion: nil)
}
}
The popover have a View inside it and when the View it's clicked with a Tap Gesture Recognizer I show LastViewController using a modal segue, the modal segue is created through the Interface Builder, not in code using an action to present the another LastViewController
Once the LastViewController is dismissed and I'm back in the MainViewController the popover remains open.
Inside the PopOverController I only have the default code nothing more.
LastViewController.swift
#IBAction func dismissVIew(sender: AnyObject) {
self.dismissViewControllerAnimated(true, completion: nil)
}
The above code is used to dismiss the LastViewController once the button inside is touched.
Storyboard
How can I dismiss the popover once the another LastViewController it's visible, or before the another LastViewController should be opened?
Thanks in advance
I have already answer same problem over here.
There scenario is different but solution is same
You have to write code for dismiss presented view controller on completion of current view controller.
Write below code on your dismissVIew method of LastViewController.swift
var tmpController :UIViewController! = self.presentingViewController;
self.dismissViewControllerAnimated(false, completion: {()->Void in
println("done");
tmpController.dismissViewControllerAnimated(false, completion: nil);
});

In your button action on the FinalViewController, have you tried:
#IBAction func dismissMe() {
//this should tell the popover to tell the main view controller to dismiss it.
self.presentingViewController!.presentingViewController!.dismissViewControllerAnimated(false, completion: nil)
}
here is how I would do it.
I usually use lazy initialization for the PopoverViewController and it's ContentViewController
lazy var popoverVC: UIPopoverController = {
let vc = UIPopoverController(contentViewController: self.contentVC)
vc.delegate = self
return vc
}()
lazy var contentVC: UIViewController = {
let vc = self.storyboard?.instantiateViewControllerWithIdentifier("ContentViewController") as UIViewController
vc.modalInPopover = true
return vc
}()
inside my contentViewController I hold a reference to the UIPopoverController.
var popoverVC: UIPopoverController!
then when I show the popover i just assign the popoverController to the contentViewController
#IBAction func showPopover(sender: UIButton) {
contentVC.popoverVC = self.popoverVC
let viewCenterRect = self.view.convertRect(self.view.bounds, toView: self.view)
popoverVC.presentPopoverFromRect(CGRectMake(CGRectGetMidX(viewCenterRect), CGRectGetMidY(viewCenterRect), 1, 1), inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.allZeros, animated: true)
}
finally I dismiss the Popover programmatically inside an #IBAction
#IBAction func dismissPopover(sender: AnyObject) {
popoverVC.dismissPopoverAnimated(true)
}
Inside the viewcontroller you can override viewWillAppear()
Inside of this block dimiss it
override public func viewWillAppear(animated: Bool)
{
super.viewWillAppear(animated)
_viewToDismiss.removeFromSuperView()
}
But the above code assumes you have a reference to the PopOver object, which I don't think is good practice based on how you described the problem.
Rather, why not have the viewcontroller that created the PopOver be responsible for destroying it. Put this in the class that listens for the button touch (which I also assumes creates the PopOver as well)
- (void)viewWillDisappear:(BOOL)animated
{
_popOver.removeFromSuperView()
}
The popover have a View inside it and when the View it's clicked with a Tap Gesture Recognizer I show another ViewController using a modal segue.
As far as I understand from what you say, you should be able to call dismissViewControllerAnimated(_:completion:) from the action associated to your tap gesture recogniser. This will dismiss the popover you presented calling:
self.presentViewController(popoverContent, animated: true, completion: nil)
You can call this method on the popover view controller itself, depending on what is more convenient for you:
The presenting view controller is responsible for dismissing the view controller it presented. If you call this method on the presented view controller itself, it automatically forwards the message to the presenting view controller.
Based on #Jageen answer
Swift 4.2
let tmpController :UIViewController! = self.presentingViewController;
self.dismiss(animated: false, completion: {()->Void in
print("done");
tmpController.dismiss(animated: false, completion: nil);
});
Usaly when you present a viewController from another viewController you do:
let vc : UIViewController = storyboard.instantiateViewControllerWithIdentifier("viewController") as UIViewController;
self.presentViewController(vc, animated: true, completion: nil);
I want to present a viewController from a SKScene. I haven't found any way of doing that.
This question might be a duplicate, but i have just found answers in objective C that doesn't make sense to me
Try the following in your scene class:
var currentViewController:UIViewController=UIApplication.sharedApplication().keyWindow.rootViewController!
currentViewController.presentViewController(viewController, animated: true, completion: nil)
I hope it helps.
