How to redirect to a specific view controller using today extension? - ios

Question

I can't redirect to a specific view controller when clicking on a button of today extension widget.
func application(_ app: UIApplication, open url: URL, options: [UIApplicationOpenURLOptionsKey : Any] = [:]) -> Bool {
let urlHost : String = url.host as String!
let mainStoryboard: UIStoryboard = UIStoryboard(name: "BLE", bundle: nil)
if(urlHost == "BLELoginViewController")
{
let innerPage: BLELoginViewController = mainStoryboard.instantiateViewController(withIdentifier: "BLELoginViewController") as! BLELoginViewController
self.window?.rootViewController = innerPage
}
return true
}
class TodayViewController: UIViewController, NCWidgetProviding {
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewDidAppear(_ animated: Bool) {
}
func widgetPerformUpdate(completionHandler: (#escaping (NCUpdateResult) -> Void)) {
// Perform any setup necessary in order to update the view.
// If an error is encountered, use NCUpdateResult.Failed
// If there's no update required, use NCUpdateResult.NoData
// If there's an update, use NCUpdateResult.NewData
completionHandler(NCUpdateResult.newData)
}
#IBAction func extensionAction(_ sender: Any) {
let url: NSURL = NSURL(string: "UEM://BLELoginViewController")!
self.extensionContext?.open(url as URL, completionHandler: nil)
}
}

Make sure that UEM is installed in your device.And have a try follow code:
let urlString = "UEM://BLELoginViewController"
if let url = URL(string: urlString) {
if #available(iOS 10, *) {
self.extensionContext?.open(url, options: [:],
completionHandler: {
(success) in
})
} else {
self.extensionContext?.open(url)
}
}
And Comment out the code first to test whether can open it not with special view:
//let urlHost : String = url.host as String!
//let mainStoryboard: UIStoryboard = UIStoryboard(name: "BLE", bundle: nil)
//if(urlHost == "BLELoginViewController")
//{
// let innerPage: BLELoginViewController = mainStoryboard.instantiateViewController(withIdentifier: "BLELoginViewController") as! BLELoginViewController
//self.window?.rootViewController = innerPage
//}
