iOS Swift - How to remove top bar back button's "Back" text?-CodePudding

I tried to identify what the "Back" text is from by the following:

  public override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    self.navigationController?.navigationBar.setTransparent(style: .default)
    print(self.navigationItem.backButtonTitle)
    print(self.navigationItem.backBarButtonItem?.title)
    print(self.navigationItem.title)
    print(self.navigationItem.titleView?.largeContentTitle)
  }

However I got all nil outputs, which means these titles are not there:

nil nil nil nil

I also tried this:

self.navigationItem.setHidesBackButton(true, animated: false)

It works but it hides the whole thing, including the back arrow "<" and the text "Back". I wanted to keep the arrow but only remove the text.

Where can I find this title or text that says "Back" and set it to empty string?

CodePudding user response：

one way is shown in attached Image.

Second one is follow:

navigationItem.backButtonTitle = ""

CodePudding user response：

This will work for you

self.navigationController?.navigationBar.topItem?.title = " "

CodePudding user response：

You can use custom left bar button item, in viewDidLoad:

let myimage = UIImage(systemName: "chevron.backward")
    navigationItem.leftBarButtonItem = UIBarButtonItem(image: myimage, style: .plain, target: self, action: #selector(handleBack))

to go back the button call handleBack func:

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