I want to disable the animation when i pop a ViewController with the back button in NavigationController.

I tried:

override func viewWillDisappear(animated: Bool) {
    super.viewWillDisappear(false)
}

But it still animates.

In the Controller that you want to have that button:

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "Back", style: .Plain, target: self, action: #selector(backTapped))
}

@objc func backTapped(sender: UIBarButtonItem) {
    navigationController?.popViewControllerAnimated(false)
}

Take into account that this way, you will lose the < icon on the back button (since you're overriding that button). However, I think it is not possible to have a custom behaviour and the < icon at the same time (unless you add the < icon as an image by yourself)

  • Then i don't get the < icon. – Lord Vermillion Nov 05 '15 at 11:02
  • That is right. I don't know if it is possible with the < icon. I'll keep trying ;) – ajpallares Nov 05 '15 at 11:03
  • You're overriding the default button, you cant keep the arrow, you have to in that case add the arrow as an image for the new button. – Arbitur Nov 05 '15 at 11:04
  • Exactly, in the solution I provided you override the button, son you lose the < icon. That's right. See the edited answer – ajpallares Nov 05 '15 at 11:05
  • This syntax changed a bit with Swift 3/4. Essentially you need to change the argument in your action to `#selector(backTapped)` and add `@objc` before your function declaration. src: https://stackoverflow.com/questions/39205613/selector-syntax-for-swift-3-0 – Braden Holt Nov 13 '18 at 20:35

Just Use this on the viewcontroller you have to pop

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(false)
    UIView.setAnimationsEnabled(false)
}

Or

override func viewDidDisappear(_ animated: Bool) {
    super.viewDidDisappear(false)
    UIView.setAnimationsEnabled(false)
}

Animation for view is totally removed. And After poped don't forget to add UIView.setAnimationsEnabled(true) on your next viewcontroller.

In which ViewController you don't want animation,
Add below lines

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    UIView.setAnimationsEnabled(false)
}
override func viewDidDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    UIView.setAnimationsEnabled(true)
}

viewWillDisappear() doesnt handle the animation, its just.

If you're using a UINavigationController

self.navigationController?.popViewController(animated: false)

If you're just using UIViewController

self.dismissViewControllerAnimated(false, completion: nil)

If you want to custom animation maybe try this:

override func viewDidLoad() {
    super.viewDidLoad()

navigationController?.navigationBar.tintColor = UIColor.white
    self.navigationItem.leftBarButtonItem = UIBarButtonItem(title: "◁", style: .plain, target: self, action: #selector(backTapped(sender:)))

}

// with fade animations

@objc func backTapped(sender: UIBarButtonItem) {
    let transition: CATransition = CATransition()
    transition.duration = 0.5
    transition.timingFunction = CAMediaTimingFunction(name: CAMediaTimingFunctionName.easeIn)
    transition.type = CATransitionType.fade
    self.navigationController!.view.layer.add(transition, forKey: nil)
    navigationController?.popViewController(animated: false)
  }

// "◁" added this way: Edit -> Emoji & Symbols

You can try this

override func viewWillDisappear(animated: Bool) {
    self.navigationController?popViewControllerAnimated(false)
}
