How to open Safari View Controller from a Webview (swift)

Question

I have an app that is currently using a webview and when certain links are clicked in the webview, it opens those links in Safari. I now want to implement the Safari View Controller(SVC) instead of booting it to the Safari app. I have done research and looked at examples on the SVC; however, all I see are ones that open the SVC from the click of a button. Does anyone have any suggestions for me to look at or to try?

Here is some of my code:

func webView(webView: UIWebView, shouldStartLoadWithRequest request: NSURLRequest, navigationType: UIWebViewNavigationType) -> Bool {
    if navigationType == UIWebViewNavigationType.LinkClicked {
        let host = request.URL!.host!;
        if (host != "www.example.com"){
            return true
        } else {
            UIApplication.sharedApplication().openURL(request.URL!)
            return false
        }
    return true

}

func showLinksClicked() {

    let safariVC = SFSafariViewController(URL: NSURL(string: "www.example.com")!)
    self.presentViewController(safariVC, animated: true, completion: nil)
    safariVC.delegate = self    }

func safariViewControllerDidFinish(controller: SFSafariViewController) {
    controller.dismissViewControllerAnimated(true, completion: nil)
}

Answer 1

import SafariServices

class ViewController: UIViewController, SFSafariViewControllerDelegate {

 override func viewDidLoad() {
     super.viewDidLoad()
     DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
         let url = URL(string: "http://www.google.com")!
         let controller = SFSafariViewController(url: url)
         self.present(controller, animated: true, completion: nil)
         controller.delegate = self
     }
 }

 func safariViewControllerDidFinish(_ controller: SFSafariViewController) {
     dismiss(animated: true)
 }
}

Swift 4.2

This is how you can open-up Safari browser within your application.

import SafariServices

whenever you want to open, like wise on

@IBAction func btnOpenWebTapped(_ sender: UIButton) {
    self.openWeb(contentLink: "https://www.google.com")
}

func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
    self.openWeb(contentLink: "https://www.google.com")
}

func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
     self.openWeb(contentLink: "https://www.google.com")
}

by write the custom function be like and you can customise the properties of the SFSafariViewController, preferredBarTintColor, preferredControlTintColor, dismissButtonStyle, barCollapsingEnabled

func openWeb(contentLink : String){
     let url = URL(string: contentLink)!
     let controller = SFSafariViewController(url: url)
     controller.preferredBarTintColor = UIColor.darkGray
     controller.preferredControlTintColor = UIColor.groupTableViewBackground
     controller.dismissButtonStyle = .close
     controller.configuration.barCollapsingEnabled = true
     self.present(controller, animated: true, completion: nil)
     controller.delegate = self
}

last and the most important thing is don't forget to bind the delegate of the SFSafariViewController with your view controller. you can do this by below mentioned extension code.

extension YourViewController: SFSafariViewControllerDelegate
{
    func safariViewControllerDidFinish(_ controller: SFSafariViewController) {
        controller.dismiss(animated: true, completion: nil)
    }
}

Happy coding Thank you :)
