如何将导航栏项目设置为“后退”按钮

Question

I have a standard left back button navigation item in table view.

I animate in a view and in that view it sets the left item to nil for a clean look. When I dismiss the animated view, i want the left item to go back to the back button that it was originally.

How can this be done?

Answer 1

在将按钮设置为Nil之前，为什么不获取对该按钮的引用，然后在加载后将其分配回去？
