I got a 3d touch function in my app delegate for the shortcutitems and it has to instantiate a viewcontroller when 3d touch item clicked from the iphone.
Here is the code:
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "com.kevinvugts.addStuf" {
let sb = UIStoryboard(name: "Main", bundle: nil)
let exerciseVC = sb.instantiateViewController(withIdentifier: "exerciseVC") as! exerciseVC
let root = UIApplication.shared.keyWindow?.rootViewController
root?.present(exerciseVC, animated: false, completion: { () -> Void in
completionHandler(true)
})
}
}
This code results in this warning/error:
Warning: Attempt to present <ActiveRest.exerciseVC: 0x131d39320> on <ActiveRest.ViewController: 0x131d0e470> whose view is not in the window hierarchy!
Has this anything to do with delay?
Thanks for any help!
Kind Regards.
view is not in the window hierarchy that means your view of your viewcontroller is not loaded in memory still. so you are unable to present viewcontroller on it. you should have to present viewcontroller from viewDidAppear of your viewcontroller (I mean from your rootviewController).
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "com.kevinvugts.addStuf" {
let sb = UIStoryboard(name: "Main", bundle: nil)
let exerciseVC = sb.instantiateViewController(withIdentifier: "exerciseVC") as! exerciseVC
window?.rootViewController?.addChildViewController(exerciseVC)
}
}
I made this change and everything works fine.

I'm developing an app that can receive Firebase's Dynamic Link. What I want is when a user click a Dynamic Link, the app redirects it to a certain UIViewController. So I have a code that looks like this on my AppDelegate.swift file:
#available(iOS 9.0, *)
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any]) -> Bool {
//return GIDSignIn.sharedInstance().handle(url)
return application(app, open: url, sourceApplication: options[UIApplication.OpenURLOptionsKey.sourceApplication] as? String, annotation: "")
}
func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
// On progress
if let dynamicLink = DynamicLinks.dynamicLinks().dynamicLink(fromCustomSchemeURL: url) {
print("open url = open dynamic link activity")
print("url = \(dynamicLink)")
let destinationVC = UIStoryboard(name: "DynamicLink", bundle: nil).instantiateViewController(withIdentifier: "DynamicLinkView") as? DynamicLinkVC
self.window?.rootViewController?.navigationController?.pushViewController(destinationVC!, animated: true)
} else {
print("open url = none")
}
return GIDSignIn.sharedInstance().handle(url)
}
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
// On progress
let handled = DynamicLinks.dynamicLinks().handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
print("dynamic link = \(dynamiclink)")
}
if handled {
let destinationVC = UIStoryboard(name: "DynamicLink", bundle: nil).instantiateViewController(withIdentifier: "DynamicLinkView") as? DynamicLinkVC
self.window?.rootViewController?.navigationController?.pushViewController(destinationVC!, animated: true)
}
return handled
}
So what happened when I click the link the app opens up immediately but it doesn't redirects to the desired UIViewController that I wanted (in this case destinationVC). It directly went to the login page as usual. But in the debug area, the link appears like this =
dynamic link = Optional(https://xxxx], match type: unique, minimumAppVersion: N/A, match message: (null)>)
Unfortunately I couldn't record the log messages when the app is not built by Xcode.
I'm very confused by this, what's wrong with my code? I'm new to iOS development so I'm not sure where did I do wrong. If you need more information feel free to ask and I will provide it to you. Any help would be appreciated. Thank you.
If your rest-of-code is working fine, and you are just facing issue while navigating to another view controller, then this solution will work for you.
If you want to open particular ViewController, while clicking on dynamic link, then update your code written within restorationHandler, below updated code will help you to redirect/navigate to particular View Controller
func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: #escaping ([UIUserActivityRestoring]?) -> Void) -> Bool {
// On progress
let handled = DynamicLinks.dynamicLinks().handleUniversalLink(userActivity.webpageURL!) { (dynamiclink, error) in
print("dynamic link = \(dynamiclink)")
}
if handled {
let mainStoryboardIpad : UIStoryboard = UIStoryboard(name: "DynamicLink", bundle: nil)
if let initialViewController : UIViewController = (mainStoryboardIpad.instantiateViewController(withIdentifier: "DynamicLinkView") as? DynamicLinkVC) {
self.window = UIWindow(frame: UIScreen.main.bounds)
self.window?.rootViewController = initialViewController
self.window?.makeKeyAndVisible()
}
return handled
}
Hope this will resolve your issue.
I am trying to get the 3d touch quick action to work, I have this code below.
I do get a print saying it was pressed but it doesn't go to the view controller I want.
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "LiveFeed" {
print("Tony: We got to live view")
guard let navVC = window?.rootViewController as? UINavigationController else { return }
let storyBoard: UIStoryboard = UIStoryboard(name: "LiveFeed", bundle: nil)
if #available(iOS 11.0, *) {
let composeViewController = storyBoard.instantiateViewController(withIdentifier: "LiveFeedMain") as! LiveFeedMain
navVC.pushViewController(composeViewController, animated: false)
} else {
// Fallback on earlier versions
}
}
}
I have this in the appDelegate
I am trying to add 3D touch quick action in my app. I have two viewContollers embedded in navigationContoller. When the user press on the 3D action, it should take them to the add events viewController. But i am getting this error
could not cast value of type 'Morning_Star_2.AddEventsViewController' (0x1000a2260) to 'UINavigationController' (0x1a79cd360).
2017-05-02 02:51:36.220324-0400 Morning Star 2[3731:895126] Could not cast value of type 'Morning_Star_2.AddEventsViewController' (0x1000a2260) to 'UINavigationController' (0x1a79cd360).
Here is my code
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "com.krp.addEvent" {
let sb = UIStoryboard(name: "Main", bundle: nil)
let addEventVC = sb.instantiateViewController(withIdentifier: "addEventVC") as! UINavigationController
self.window?.rootViewController?.present(addEventVC, animated: true, completion: nil)
}
}
I tried changing as! UINavigationController to as! AddEventsViewController. It works, but then it won't show the navigation bar on the top on my add viewController as it normally would if you open the app normally.
Here is my main.storyboard
You shouldn't cast AddEventsViewController to UINavigationController, because it isn't UINavigationController, is just subclass of UIViewController. But as I see, your rootViewController is. So you need to cast it to UINavigationController, and then push your AddEventsViewController, instead present, and you will see NavigationBar
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "com.krp.addEvent" {
let sb = UIStoryboard(name: "Main", bundle: nil)
let addEventVC = sb.instantiateViewController(withIdentifier: "addEventVC") as! AddEventsViewController
if let navigationController = window?.rootViewController as? UINavigationController {
navigationController.pushViewController(addEventVC, animated: true)
}
}
}
I implemented 3D touch before making changes to my UI, which all i did was embedded my viewControllers into navigation controller. After those changes, my quick add 3D shortcut crashes the app every time i try to launch it using 3D touch. If I launch the app regularly, the app works just fine.
Here is my main.storyboard
Here is my appDelegate code:
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "com.krp.addEvent" {
let sb = UIStoryboard(name: "Main", bundle: nil)
let addEventVC = sb.instantiateViewController(withIdentifier: "addEventVC") as! ViewController
let root = UIApplication.shared.keyWindow?.rootViewController
root?.present(addEventVC, animated: false, completion: { () -> Void in completionHandler(true)})
}
}
I have a 3D Force Touch Action that I set up in my Info.plist. Now I want that when the 3D Action is running it presents a view controller that I gave a Storyboard ID and I need to do this in the AppDelegate.
I used the performActionForShortCutItem function.
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if let tabVC = self.window?.rootViewController as? UITabBarController {
if shortcutItem.type == "Hausaufgaben" {
tabVC.selectedIndex = 1
tabVC.performSegue(withIdentifier: "gotoHausaufgaben", sender: nil)
}
}
}
func application(_ application: UIApplication, performActionFor shortcutItem: UIApplicationShortcutItem, completionHandler: #escaping (Bool) -> Void) {
if shortcutItem.type == "Hausaufgaben" {
self.window = UIWindow(frame: UIScreen.main.bounds)
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let initialViewController = storyboard.instantiateViewController(withIdentifier: "YOUR PAGE Identifier")
self.window?.rootViewController = initialViewController
self.window?.makeKeyAndVisible()
}
}
