I'm using UIDocumentPickerViewController for derives(likes Dropbox, google etc.).
let importMenu = UIDocumentPickerViewController(documentTypes: [String(kUTTypeContent),String(kUTTypeItem)], in: .import)
importMenu.delegate = self
importMenu.modalPresentationStyle = .formSheet
self.present(importMenu, animated: true, completion: nil)
But now i'm trying to customised UIDocumentPickerViewController. How can i add more option in menu like camera, gallery etc.
I can't use bellow code because UIDocumentMenuViewController is deprecated now.
func addOption(withTitle title: String,
image: UIImage?,
order: UIDocumentMenuOrder,
handler: #escaping () -> Void)
Is there any other way that i can customised UIDocumentPickerViewController and add more option in that.
Thanks

I am trying to open specific view controller on widgets click , but can not able to open it , i am able to open app using url schema but i want to open specific view controller how can i do this, here is code for open app using url schema :
#IBAction func open_app(_ sender: Any)
{ extensionContext?.open(URL(string: "open://")! ,
completionHandler: nil)
}
on button click i am opeing app sucessfully using url schema. but now i want to open specific view controller on that click how can i do this?
According to your requirement, I have created a sample to get this working correctly.
1. First of all in TodayViewController interface, create 3 different UIButtons and give their tag values to uniquely identify them.
Here I have given tags as: 1, 2, 3 to First, Second and Third UIButton.
2. Next you need to write the code to open your Containing App from Today Extension. In TodayViewController create an #IBAction for and connect it to all three UIButtons.
#IBAction func openAppController(_ sender: UIButton)
{
if let url = URL(string: "open://\(sender.tag)")
{
self.extensionContext?.open(url, completionHandler: nil)
}
}
In the above code, tag will be added to the url scheme to identify which UIViewController needs to be opened on UIButton press. So the url will look something like: open://1
3. In the Containing App's URL Types need to make an entry for URL Scheme, i.e
As evident from the above screenshot, there is no need to make entry for each url that you want to open from your extensions. URLs having same url scheme have only a single entry.
4. When the containing app is opened from extension, you can get the handle in AppDelegate’s application(_ : url: sourceApplication: annotation: ) method. Here, you can handle which controller to open i.e.
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool
{
if url.scheme == "open"
{
switch url.host
{
case "1":
//Open First View Controller
case "2":
//Open Second View Controller
case "3":
//Open Third View Controller
default:
break
}
}
return true
}
url.scheme identifies the scheme of URL i.e. open and url.host identifies the host component in the URL which is currently set to the UIButton's tag value which you can use to uniquely identify which UIButton is pressed and what to de next accordingly.
For more on Today Extensions, you can refer to: https://hackernoon.com/app-extensions-and-today-extensions-widget-in-ios-10-e2d9fd9957a8
Let me know if you still face any issues regarding this.
add a new scheme for your App
enter image description here
as Shown above image...
then, write a code below on IBAction of your Today Extension
#IBAction func btnFirstWidgetAction() {
let url: URL? = URL(string: "schemename://secondViewController")!
if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}
#IBAction func btnSecondWidgetAction() {
let url: URL? = URL(string: "schemename://secondViewController")!
if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}
#IBAction func btnThirdWidgetAction() {
let url: URL? = URL(string: "schemename://thirdViewController")!
if let appurl = url { self.extensionContext!.open(appurl, completionHandler: nil) }
}
than, add method application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) in AppDelegate file and write code to redirect in specific ViewController in this method.
//call when tap on Extension and get url that is set into a ToadyExtension swift file...
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
let urlPath : String = url.absoluteString
print(urlPath)
if self.isContainString(urlPath, subString: "firstViewController") {
//here go to firstViewController view controller
}
else if self.isContainString(urlPath, subString: "firstViewController") {
//here go to secondViewController view controller
}
else {
//here go to thirdViewController view controller
}
return true
}
this method used for check your string is contains as sub string that are given in widget button action. if contain than true otherwise false
func isContainString(_ string: String, subString: String) -> Bool {
if (string as NSString).range(of: subString).location != NSNotFound { return true }
else { return false }
}
In xCode 11 if you are using sceneDelegate, follow the same logic as described by Malik and Mahesh but use the following function in the SceneDelegate instead:
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
if let url = URLContexts.first?.url {
//Do stuff with the url
}
}
(instead of application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool)
In details:
First:
Add a url scheme in your project -> info -> url Types -> add url Scheme. Here you can get started by filling the 'URL Schemes" field only (with your app name for instance).
Second:
In your extension, use the following function (called by a button for instance):
let urlString = "MyAppName://host/path"
if let url = URL(string: urlString)
{
self?.extensionContext?.open(url, completionHandler: nil)
}
Third:
Implement your logic in Scene Delegate with:
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
if let url = URLContexts.first?.url {
//Do stuff with the url
}
}
Swift5
Step1: select project>info>url types>add url scheme
step2: go to the button action method and use this code
let tag = 1
if let url = URL(string: "open://\(tag)")
{
self.extensionContext?.open(url, completionHandler: nil)
}
step 3: welcome you get the control of your host app, jus add this in app delegate method
func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool
{
if url.scheme == "open"
{
switch url.host
{
case "1":
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "ViewController") as! ViewController
self.window?.rootViewController = vc
self.window?.makeKeyAndVisible()
default:
break
}
}
return true
}
Congrats! you open the controller.
I have a Table View Controller as a tab. In it, there's a button that takes you to a Facebook profile:
func didTapFacebook() {
let url = URL(string: "http://www.facebook.com/" + myFacebookId)
if UIApplication.shared.canOpenURL(url!) {
UIApplication.shared.open(url!, options: [:], completionHandler: nil)
}
}
Works fine every time you press the button.
From another tab, there's a button that presents modally a navigation controller with Table View Controller as its root:
func segueToTable(_ sender: UIViewController, tvc: MyTableViewController, completion: #escaping ((_ done: Bool) -> Void)) {
let nc = MyNavigationController(rootViewController: tvc)
sender.present(nc, animated: true, completion: {
completion(true)
})
}
…
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let tvc = storyboard.instantiateViewController(withIdentifier: "TVC") as! MyTableViewController
segueToTable(self, tvc: tvc, completion: { done in
print(“segue complete”)
})
Now once you tap the same button to go to Facebook profile (or Twitter button, basically anything that causes the app to go to background), this warning occurs (there is no keyboard displayed on the screen at this time):
Cannot snapshot view (>) with afterScreenUpdates:NO, because the view is not in a window. Use afterScreenUpdates:YES.
Returning to the app and pressing the button again causes this warning to appear (and every attempt after that):
Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates.
I realize this is related to snapshotting a view that automatically occurs prior to entering the background. It appears for some reason it doesn't like doing that within a view that was presented modally. I've tried a variety of things based on other posts but cannot get the warnings to go away.
Any help is appreciated.
The navigation controller is not the initial view controller. It is being instantiated in the initial VC and supplied with a root controller, the second VC. When I call present view controller function I cannot change the way in which this new VC in being presented, it always appears from the bottom. I did not find how to make it come from right to left. I tried to change who gets the call to modalPresentaionStyle from the second VC to the nav con and back but no change.
Code listing below. Thank you for your help.
#objc fileprivate func showRegisterScreen() {
let registerAccountVC = RegisterAccountVC()
let navigationController = UINavigationController(rootViewController: registerAccountVC)
navigationController.modalPresentationStyle = .pageSheet
present(navigationController, animated: true, completion: nil)
}
This will add a custom animation from right to left.
let transition = CATransition.init()
transition.duration = 0.4
transition.timingFunction = CAMediaTimingFunction.init(name: kCAMediaTimingFunctionEaseInEaseOut)
transition.type = kCATransitionPush
transition.subtype = kCATransitionFromRight
view.window?.layer.add(transition, forKey: nil)
present(navigationController, animated: false, completion: nil)
I have 2 view controllers on my storyboard: viewController1(it input point) and viewController2. After loading the application i want to automatic presenting viewController2 after viewController1.
How i can do that?
if you want to go to second viewcontroller you can add this code to you viewDidLoad method:
let secondViewController = self.storyboard?.instantiateViewController(withIdentifier: "yourIdentifier") as! secondViewController
self.navigationController?.pushViewController(secondViewController, animated: true)
remeber to add a identifier for the second viewcontroller in storyboard and chenge the identifier that you use with "yourIdentifier"
if you don't want a animation put the animated: true to false.
if you dont want to show the fist viewcontroller, go into you storyboard and click on the second viewcontroller, then in the right side on attributes inspector select the box int the image:
For change viewcontroller you have to embed the first viewcontroller with a navigation controller, if you don't know how to do it, just select the fisrt viewcontroller and do like the image, click in navigation controller
Have you tried to show it in func viewDidLoad() {} like:
override func viewDidLoad() {
// ...
self.present(viewController, animated: true, completion: nil)
}
If you want to straight up load a different view controller you can do this in your app delegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewController(withIdentifier: "put your identifier here")
self.window?.rootViewController = vc
return true
}
I am trying to create a Cocoa Touch Framework for media needs.
while using my framework, to get a photo from Photo Library, the callback is not getting fired.
Following is a snippet of myframework code:
public func importFromGallery (viewCtrl: UIViewController, resultCallback: #escaping (_ image: UIImage, _ error: Int) -> Void) {
let imageController = UIImagePickerController()
imageController.delegate = self
imageController.sourceType = UIImagePickerControllerSourceType.photoLibrary
viewCtrl.present(imageController, animated: true, completion: {
() in
print("viewCtrl.present completion") // Can see this in console
})
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
print("didFinishPickingMediaWithInfo") // Can't see this!
}
is not getting a called without any error or warning.
However, the same code works if I try to use directly in a single view application.
