iOS10 跳转后navigationBar 按钮和title消失

Question

升级iOS后，APP中多个页面跳转后导航栏上的按钮和标题消失

Answer 1

Same problem encountered

Answer 2

Usually it only appears when you customize the navigationBar. Is there any code?

Answer 3

Solved it, I spent a long time looking for a solution. Because I need to switch between transparent and opaque navigation, I used the navigationbar extension. I used the one written by this master: https://github.com/ltebean/LT..., so the problem was solved after the update.
