IOS Swift: Update navigation button with "Back" text

Question

There are few similar kind of questions asked and answered by many on Stackoverflow. But none of solution matches with my requirement.

I am using Swift3 for IOS mobile app development and used Navigation controller to manage the navigation. I gave title to all pages using below code.

self.title = "Title"

When I move to next page, then it shows me back button with the earlier page title. For some pages, title is long and it disturbs my header section of page.

Instead of page title, I want to change button text to "Back". Any idea how to do that?

No. I want button text as "Back" and not the page title as back. — NGR

if you are using storyboard then you can set back button title there, click on ViewController -> Navigation Item -> Back Button and set "Back" title.

alternatively you can set title in ViewWillApear and change it to "Back" in viewWillDisappear method

override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.title = "My Title"
}

override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        self.title = "Back"
}

This is what I was expecting. It worked perfectly with adding those 2 method. Though I didn't find "Navigation Item" in Xcode.

If you have embedded your ViewController in UINavigationController then you will find it below your View hierarchy or when you tap on navigation bar area in your ViewController.

In your prepare function before the segue do this:

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
    let backItem = UIBarButtonItem()
    backItem.title = "Back" // Change to desired title here
    navigationItem.backBarButtonItem = backItem
}

Try this:

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

It should work :)
