how do I dismiss keyboard when a UIView receives accessibilityElementDidLoseFocus

I have a search view controller with the search bar on top. When searching, the keyboard shows up and stay up even when accessibilityElementDidLoseFocus is called on the search bar.

I would like to dismiss the keyboard when that happens. Can I do that without subclassing the search bar I am using?

Solution

  • Here is a way to do that without subclassing:

    // Assuming you have an accessibility element with an identifier
let myAccessibilityElement = UIAccessibilityElement(accessibilityContainer: self)

// Observe accessibility focus changes
NotificationCenter.default.addObserver(
    self, 
    selector: #selector(accessibilityElementDidLoseFocus), 
    name: UIAccessibilityElement.didLoseFocusNotification, 
    object: myAccessibilityElement
)

@objc func accessibilityElementDidLoseFocus() {
    // Dismiss keyboard here
}
