How to launch a parent iOS App from its App Extension

Question

Does any one know how to launch the parent app from the app extension\'s view controller?

I just want to launch the main app from its app extension.

Answer 1

it is working in my current working app using action extension

1- in parent app plist add custom URL like

2- add both functions in your extension view controller

func openURL(url: NSURL) -> Bool {
    do {
        let application = try self.sharedApplication()
        return application.performSelector(inBackground: "openURL:", with: url) != nil
    }
    catch {
        return false
    }
}

func sharedApplication() throws -> UIApplication {
    var responder: UIResponder? = self
    while responder != nil {
        if let application = responder as? UIApplication {
            return application
        }

        responder = responder?.next
    }

    throw NSError(domain: "UIInputViewController+sharedApplication.swift", code: 1, userInfo: nil)
}

3- call this function in your button action or somewhere you want to do

self.openURL(url: NSURL(string:"openPdf://HomeVC")!)

here homevc is the class name of your View controller which should be presented

4- in your app delegate implement the method like

  func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    let urlPath : String = url.absoluteString
    print(urlPath)
    if urlPath.contains("HomeVC"){
        //here go to firstViewController view controller
        self.window = UIWindow(frame: UIScreen.main.bounds)

        let storyboard = UIStoryboard(name: "Main", bundle: nil)

        let initialViewController = storyboard.instantiateViewController(withIdentifier: "homeVC")

        self.window?.rootViewController = initialViewController
        self.window?.makeKeyAndVisible()
    }
}

I hope will work fine, can also share data between extension app and parent app
