Swift：当SearchBar处于活动状态时，应按两次Back按钮

Question

I have a UITableViewController embedded in a navigation bar and standard Search bar implementation. I don't hide the navigation bar while the search bar is active. The problem is that while the search bar is active, every button in the navigation bar, like a "Back" button, should be pressed twice— the first time to make the search bar inactive. How can I avoid that? Thank you.

Answer 1

add this codes on viewDidLoad

    self.definesPresentationContext = true

and add this if your navigationBar is Opaque

    self.extendedLayoutIncludesOpaqueBars = true
