swift 3 IOS - Back button issue

Question

I'm trying to go from viewController to Another

my problem is that the back button is showing as "<" and not "< Back" and i didn't understand why, especially cause i'm able to go from this viewController to another one, and the back button is perfect

do anyone faced the same problem ? and how could i solve it ?

Answer 1

不看代码很难看，但是如果您想解决它，您可以看看有关如何更改后退按钮标题的许多其他答案。

Answer 2

This can happen if the title of the new view controller is too long. I think the system in this scenario will favor removing "back" in order to make room for the long title

So try shortening the view controller title

Answer 3

You can customize the text of the back button with the following code...

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {

    // your segue prep code
    self.navigationController?.navigationBar.topItem?.title = "Back"


}
