How to create custom back button in navigationBar in swift?-CodePudding

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

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

CodePudding user response：

You can remove default back Button by following way:

navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)

And manually add navigation items in left side using navigationitem.leftBarButtonItem.

Hope it helps!

CodePudding user response：

just add left bar button item

navigationItem.leftBarButtonItem = UIBarButtonItem(image: UIImage(named: "back-icon"), style: .plain, target: self, action: #selector(backTapped))

and action handle with

@objc
func backTapped() {
    navigationController?.popViewController(animated: true)
}

CodePudding user response：

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()
