从视图即按即按视图控制器无法快速运行

Question

I tried to push to a view controller from a view class using tap gesture action. All the below lines are executed, but the control not pushing to respective view controller. I need to push to that view controller, but not to set the controller as root view,because i need to navigate back to some other navigated view controller. Any one please help me.

let webViewController = R2WebViewViewController()
currentWindow.rootViewController?.navigationController?.pushViewController(webViewController, animated: true)

Answer 1

try this

(currentWindow?.rootViewController as! UINavigationController).pushViewController(webViewController, animated: true)

Your root must be navVC

Answer 2

currentWindow.rootViewController?.navigationController?

Your problem is that your rootViewController is probably an UINavigationController already, so you should do:

let webViewController = R2WebViewViewController()
(currentWindow.rootViewController as? UINavigationController).pushViewController(webViewController, animated: true)
