Search bar not showing up on the navigation bar iOS 11

Question

I am pushing a viewController where I want a searchBar, but search bar is not showing at all. Below is the code. Am I missing something?

var searchController = UISearchController(searchResultsController: nil)
searchController.searchResultsUpdater = self
searchController.obscuresBackgroundDuringPresentation = false
searchController.searchBar.placeholder = "Search here..."
definesPresentationContext = true
searchController.searchBar.delegate = self
searchController.searchBar.sizeToFit()
if #available(iOS 11.0, *) {

    self.navigationItem.searchController = searchController
} else {
    // Fallback on earlier versions
    navigationItem.titleView = searchController.searchBar
    navigationItem.titleView?.layoutSubviews()
}

I used your code it is working – Devilfish

How you are pushing new view controller? – Decaliter

I am using this - let destinationVC = storyboard.instantiateViewController(withIdentifier:"someVC") vc.show(destinationVC, sender: self) – Condescendence

This got solved by adding this line - navigationItem.hidesSearchBarWhenScrolling = false – Condescendence

Now the problem is the search bar is coming below the navigationBar. How can we have searchbar on top of navigation bar? – Condescendence

I dont think you can have it above the navigation bar unless you create your own – Cavernous

You can hide the navigation bar whilst searching using searchController.hidesNavigationBarDuringPresentation = true – Cavernous

Did you find the solution? @AjayKumar – Alsatian

Answer 1

You need to add this line to your code:

navigationItem.hidesSearchBarWhenScrolling = false

That removes hiding searchBar while scrolling and shows it on pushing your view controller.

So, navigationItem.hidesSearchWhenScrolling only works when you set the searchController property of navigationItem NOT when you set the navigationItem.titleView to searchBar.
