Is there a workaround to bring the method "present" in a UIimageView class? - swift4

Question

I created a class for my Logo UIimageView which is on every ViewController in my app. Now I want to create a tapGesture to jump back to the Home ViewController when it is tapped like Logos on Homepages back to index. How can I get the present method to work in the class UIimageView?
import Foundation
import UIKit
class LogoImageView: UIImageView {
override func awakeFromNib() {
super.awakeFromNib()
self.isUserInteractionEnabled = true
let TapGesture = UITapGestureRecognizer(target: self, action: #selector(self.imageTapped))
self.addGestureRecognizer(TapGesture)
}
#objc func imageTapped() {
let mainStoryboad = UIStoryboard(name: "Main", bundle: Bundle.main)
guard let destinationViewController = mainStoryboad.instantiateViewController(withIdentifier: "ViewController") as? ViewController else {
return
}
present(destinationViewController, animated: true, completion: nil)
}
}

I´ve got the solution for my problem. I added an extension to check the current ViewController to use the present method. Now I´m able to add every UIimageview this class and it brings me back to the root viewcontroller.
import Foundation
import UIKit
class LogoImageView: UIImageView {
override func awakeFromNib() {
super.awakeFromNib()
self.isUserInteractionEnabled = true
let TapGesture = UITapGestureRecognizer(target: self, action: #selector(self
.imageTapped))
self.addGestureRecognizer(TapGesture)
}
#objc func imageTapped() {
let mainStoryboad = UIStoryboard(name: "Main", bundle: Bundle.main)
guard let destinationViewController = mainStoryboad.instantiateViewController(withIdentifier: "ViewController") as? ViewController else {
return
}
guard let currentViewController = UIApplication.shared.keyWindow?.topMostViewController() else {
return
}
destinationViewController.modalTransitionStyle = .flipHorizontal
currentViewController.present(destinationViewController, animated: true, completion: nil)
}
}
extension UIWindow {
func topMostViewController() -> UIViewController? {
guard let rootViewController = self.rootViewController else {
return nil
}
return topViewController(for: rootViewController)
}
func topViewController(for rootViewController: UIViewController?) -> UIViewController? {
guard let rootViewController = rootViewController else {
return nil
}
guard let presentedViewController = rootViewController.presentedViewController else {
return rootViewController
}
switch presentedViewController {
case is UINavigationController:
let navigationController = presentedViewController as! UINavigationController
return topViewController(for: navigationController.viewControllers.last)
case is UITabBarController:
let tabBarController = presentedViewController as! UITabBarController
return topViewController(for: tabBarController.selectedViewController)
default:
return topViewController(for: presentedViewController)
}
}
}
