Removing viewcontrollers from navigation stack

by

Use this code and enjoy:

NSMutableArray *navigationArray = [[NSMutableArray alloc] initWithArray: self.navigationController.viewControllers];

// [navigationArray removeAllObjects];    // This is just for remove all view controller from navigation stack.
[navigationArray removeObjectAtIndex: 2];  // You can pass your index here
self.navigationController.viewControllers = navigationArray;
[navigationArray release];

Hope this will help you.

Edit: Swift Code

guard let navigationController = self.navigationController else { return }
var navigationArray = navigationController.viewControllers // To get all UIViewController stack as Array
navigationArray.remove(at: navigationArray.count - 2) // To remove previous UIViewController
self.navigationController?.viewControllers = navigationArray

Edit: To remove all ViewController except last one -> no Back Button in the upper left corner

guard let navigationController = self.navigationController else { return }
var navigationArray = navigationController.viewControllers // To get all UIViewController stack as Array
let temp = navigationArray.last
navigationArray.removeAll()
navigationArray.append(temp!) //To remove all previous UIViewController except the last one
self.navigationController?.viewControllers = navigationArray
