Search cursor disappearing when cancel button hidden - swift

Question

I followed the great directions in this post to subclass a search bar and search controller that does not show the cancel button. However, there is now no cursor in my search bar when I start editing. I've tried setting the tint for the search bar, which I've seen as an answer in many posts, in various delegate methods. The tint is technically being set correctly, as I can see when I test it by setting my search controller to be the standard UISearchController. But as soon as I set it to my subclass SearchControllerWithoutCancel the cursor goes away.
Here are my subclasses:
class SearchBarWithoutCancel: UISearchBar {
override func layoutSubviews() {
super.layoutSubviews()
setShowsCancelButton(false, animated: false)
}
}
class SearchControllerWithoutCancel: UISearchController, UISearchBarDelegate {
lazy var _searchBar: SearchBarWithoutCancel = {
[unowned self] in
let result = SearchBarWithoutCancel(frame: .zero)
result.delegate = self
return result
}()
override var searchBar: UISearchBar {
get {
return _searchBar
}
}
}
And here's my addSearchController method which I call from viewDidLoad()
func addSearchController() {
searchController.searchResultsUpdater = self
searchController.dimsBackgroundDuringPresentation = false
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.autocapitalizationType = .none
searchController.searchBar.searchBarStyle = .minimal
searchController.searchBar.tintColor = UIColor.black
self.definesPresentationContext = true
tableView.tableHeaderView = searchController.searchBar
}
Has anyone encountered this before? Thanks :)

Answer 1

indeed when the cancel button is hidden, the cursor tint color resets itself
in your SearchBarWithoutCancel remove the layoutSubviews and override setShowsCancelButton :
override func setShowsCancelButton(_ showsCancelButton: Bool, animated: Bool) {
//nothing
}}
objective-c version
-(void) setShowsCancelButton:(BOOL)show animated:(BOOL)animated
{
//nothing
}
