How to create custom back button in navigationBar in swift?

public override func viewDidLoad() {
    super.viewDidLoad()
    navigationItem.backBarButtonItem = .init(image: "back_icon".image, style: .plain, target: nil, action: nil)
}

For this above code, I got my back_icon image with the default back image

Output Image

Any idea to remove the default back button at the same time preserving swipe edge to pop viewController.

Solution

  • You should be able to change the back button image globally by using

    UINavigationBar.appearance().backIndicatorImage = UIImage(named: "arrow-back")
UINavigationBar.appearance().backIndicatorTransitionMaskImage = UIImage(named: "arrow-back")

    And if you only want to change it in some places:

    navigationController?.navigationBar.backIndicatorImage = UIImage(named: "arrow-back")
navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage(named: "arrow-back")

    Removing an arrow at all would be as simple as

    navigationController?.navigationBar.backIndicatorImage = UIImage()
navigationController?.navigationBar.backIndicatorTransitionMaskImage = UIImage()
