从后退按钮中删除文本保留图标 [英] Remove text from Back button keeping the icon

问题描述

我想从后退按钮中删除文本，但我想保留图标.我试过了

I want to remove the text from the back button, but I want to keep the icon. I have tried

let backButton = UIBarButtonItem(title: "", style: UIBarButtonItemStyle.Plain, target: navigationController, action: nil)
navigationItem.leftBarButtonItem = backButton

但是，这会完全删除文本和图标.

However, this removes completely the text and the icon.

推荐答案

@rmd2 的方法几乎是正确的，但是你应该选择返回按钮将指向的控制器的导航栏并键入 "" 在后退按钮字段中.

The method of @rmd2 is almost right, but instead you should select the navigation bar of the controller to which back button will point to and type " " in the Back Button field.
