I'm looking to use the SFSafariViewController and have it automatically load a website when the app is opened. Is this possible?
What I have so far (brand new single ios app):
// ViewController.swift
let urlString = "https://stackoverflow.com"
#IBAction func launchSFSafariViewController(sender: AnyObject) {
if let url = NSURL(string: urlString) {
let vc = SFSafariViewController(URL: url, entersReaderIfAvailable: true)
vc.delegate = self
presentViewController(vc, animated: true, completion: nil)
}
}
How do I connect the action to the main view controller via the storyboard? All the articles I see only discuss connecting a button to an action.
Implement viewDidAppear to perform the presentation. (You will need to use a Bool flag, though, to make sure this doesn't happen when you dismiss the presented view controller and viewDidAppear is called again!)

Problem:
I would like SFSafariViewController to autoplay a YouTube video in full screen.
Code:
import SafariServices
#objc func handleYTTap(_ sender: UIGestureRecognizer) {
let youtubeVideoURL = "https://youtu.be/d9MyW72ELq0"
let bookmark = NSURL(string: youtubeVideoURL)
let safari = SFSafariViewController(url: bookmark as! URL)
if(UIDevice.current.userInterfaceIdiom == .pad) {
safari.modalPresentationStyle = .fullScreen
}else{
safari.modalPresentationStyle = .fullScreen
}
self.present(safari, animated: true, completion: nil)
}
Tried Solutions:
I have tried to implement
"?playsinline=1?autoplay=1".
to the url but still cant get the SFSafariViewController to autoplay in full screen. is this even possible to do without creating a custom view or using a library of some sort?
Using SFSafariViewController, works well but for some reason when I go to this webpage [knowitall.ch], it starts up by opening a zoomed view? with a small black box that I need to press to get the full webpage.
My code couldn't be simpler.
if let url = URL(string: url2U) {
let vc = SFSafariViewController(url: url, entersReaderIfAvailable: true)
vc.delegate = self
present(vc, animated: true)
}
If I press the box I get the correct view, how to code around this so I open with the second view here? black box not required :)
That "zoomed view" is the Reader Mode. It shows up because you asked for it. Set entersReaderIfAvailable to false if you don't want it. Also, init(url:entersReaderIfAvailable:) has been deprecated in iOS 11. You need to initialize it with a config object:
if let url = URL(string: url2U) {
let vc: SFSafariViewController
if #available(iOS 11.0, *) {
let config = SFSafariViewController.Configuration()
config.entersReaderIfAvailable = false
vc = SFSafariViewController(url: url, configuration: config)
} else {
vc = SFSafariViewController(url: url, entersReaderIfAvailable: false)
}
vc.delegate = self
present(vc, animated: true)
}
I'm using Safari Services kit to present a web view when an SCNode is clicked. However, when I go back from the safariVC to my VC with the sceneView, the sceneView is frozen even though I restart the session by re-running the session.
I read on this website that presenting another VC kills the scene view thread and I would just like confirmation. Basically I want to know whether it is possible to present another VC and be able to go back to the sceneView and "resume" the scenView
Note:
VC = ViewController
Code
How I present my safari web VC
func presentWebView(){
if let url = URL(string: "https://www.amazon.com/"){
let safariVC = SFSafariViewController(url: url)
self.present(safariVC, animated: true, completion: nil)
}
}
How I restart my session
if let worldSessionConfig = sessionConfig as? ARWorldTrackingSessionConfiguration {
worldSessionConfig.planeDetection = .horizontal
session.run(worldSessionConfig, options: [.resetTracking, .removeExistingAnchors])
}
Use sceneView.session.pause() when you present safariVC and then use sceneView.session.run to restart session when safariVC is dismissed.
I am trying to open a URL using Safari when the app gets a push notification. This works successfully when the app is in the first viewcontroller. But if the app is further into the program I get an error
<SFSafariViewController: 0x10b20ae60> on <AdViewController: 0x100b14530> whose view is not in the window hierarchy!
(AdViewController is my first view controller, so it is still focused on that one. )
I have searched this site and have tried all the suggestions for this error but have come up short. Currently, my code looks like this:
if MessageUrl != nil , let url = URL(string: MessageUrl!) {
let safari = SFSafariViewController(url: url)
self.window?.rootViewController?.presentedViewController?.present(safari, animated: true, completion: nil)
}
Get top most UIViewController I used extension UIApplication in Appdeleagte from the "swift 3" answer at bottom of that page and changed my code to:
if MessageUrl != nil , let url = URL(string: MessageUrl!) {
let safari = SFSafariViewController(url: url)
UIApplication.topViewController()?.present(safari, animated: true, completion: nil)
}
I'm using a SFSafariViewController. The initial url that loads redirects to another url. I need to get the current url bar that SFSafariViewController has.
It's successfully redirecting because I can see it in the url bar but I got no access not even from delegate methods.
Before that, I was using UIWebView and it worked fine but suddenly it doesn't redirect anymore.
This is my code for SFSafariViewController:
override func viewDidAppear(_ animated: Bool) {
safari = SFSafariViewController(url: URL(string:"https://api.instagram.com/oauth/authorize/?client_id=client_code&redirect_uri=http://localhost&response_type=code")!)
safari.delegate = self
self.present(safari, animated: true, completion: nil)
}
It's presenting rightly but I need access to the current url.
Thanks in advance.
