I want customised navigation bar back button title with action.
My Image :
I need back button like this. Here i added text successfully, but not back arrow. Here my code has action for back button.
This is my code
//Custom barButtonItem with custom alert function
self.navigationItem.hidesBackButton = true
let newBackButton = UIBarButtonItem(title: "< Dialer", style: .plain, target: self, action: #selector(back(sender:)))
self.navigationItem.leftBarButtonItem = newBackButton
func backButtonConfiguration(_ title : String, backImageName : String) {
let backImage : UIImage = UIImage(named: backImageName)!
self.navigationBar.backIndicatorImage = backImage.withRenderingMode(.alwaysTemplate)
self.navigationBar.backIndicatorTransitionMaskImage = backImage
self.navigationBar.backItem?.title = title
}
Update
if we need custom action for back button then we have to add custom BarButtonItem. And if we need bar back button look same as built in back button then we can create custom view and use it it as a bar button item
weak var customView : UIView!
lazy var leftBarButtonView : UIBarButtonItem! = {
let btnBack = UIBarButtonItem(customView: customView)
let gesture = UITapGestureRecognizer(target: self, action: #selector(btnButtonClicked(_:)))
gesture.numberOfTapsRequired = 1
self.customView.addGestureRecognizer(gesture)
self.customView.isUserInteractionEnabled = true
return btnBack
}()
@objc func btnButtonClicked(_ gesture : UITapGestureRecognizer) {
self.navigationController?.popViewController(animated: true)
}
self.navigationItem.leftBarButtonItems = [leftBarButtonView]
