Nav button needs to go form the last view to the first view - swift

Question

Hello, I have provided the link above to show a visual view of what I am trying to accomplish. So each button is a segue to the next view except the last button is not which is intended. The last two views with the back buttons at the top that are automatically included because of the nav controller I want to have those back buttons go to the first view controller. How can I do this either with xcode and swift?

Answer 1

If you want to remove all the navigation controller then use this code
Put this code in the button selector method
self.navigationController!.viewControllers.removeAll()
OR
navigationController?.popToRootViewController(animated: true)
OR
If you don’t have a Navigation Controller and use dismissViewController method, you still can use:
view.window?.rootViewController?.dismiss(animated: true, completion: nil)
Now comes the back button code:
override func viewDidLoad() {
super.viewDidLoad()
var backbutton = UIButton(type: .Custom)
backbutton.setImage(UIImage(named: "BackButton.png"), forState: .Normal) // Any image can be used. download back button image from any site or whatever you wanna use.
backbutton.setTitle("Back", forState: .Normal)
backbutton.setTitleColor(backbutton.tintColor, forState: .Normal) // You can change the TitleColor
backbutton.addTarget(self, action: "backAction", forControlEvents: .TouchUpInside)
self.navigationItem.leftBarButtonItem = UIBarButtonItem(customView: backbutton)
}
func backAction() -> Void {
//here put code from above whichever you wanna use for example I'm using one
self.navigationController?.popToRootViewController(animated: true)
}
