Dismiss popover viewController when tapped elsewhere - ios

Question

I'm presenting a popover viewController on top of a UITableView. How can i dismiss this popover when tapped outside of it? I'm trying to call it from the didSelectRow method, but the tap isn't detected. Any suggestion?
Thanks!
this is my code:
let addFriendsPopoverViewController = storyboard?.instantiateViewController(withIdentifier: "HomePopOver") as! HomePopOverViewController
addFriendsPopoverViewController.index = (sender.tag)!
addFriendsPopoverViewController.delegate = self
addFriendsPopoverViewController.isModalInPopover = true
addFriendsPopoverViewController.modalPresentationStyle = UIModalPresentationStyle.popover
addFriendsPopoverViewController.preferredContentSize = CGSize(width: 210, height: 40)
let popoverMenuViewController = addFriendsPopoverViewController.popoverPresentationController
popoverMenuViewController!.permittedArrowDirections = .down
popoverMenuViewController!.delegate = self
popoverMenuViewController!.sourceView = self.view
popoverMenuViewController!.sourceRect = CGRect(
x: UIScreen.main.bounds.width - 105,
y: 50,
width: 1,
height: 1)
present(
addFriendsPopoverViewController,
animated: true,
completion: nil)

Answer 1

A view controller presented in a UIPopoverController, or presented using UIModalPresentationPopover, will automatically be dismissed when the user taps outside the popover, unless you have set isModalInPopover or implemented the delegate method which prevents it.
If you need some code to run when this happens, then you'll need to implement a delegate method too.
Which specific methods depend on whether you're using a UIPopoverController or UIModalPresentationPopover. The tags on your question suggest the former, but that's quite an old-fashioned (and deprecated) way of doing it.

Answer 2

Even though you have found your answer, I wanted to share my solution because I had the same problem and after I spent some time to figure it out, I have found what the problem was. It was not actually because of something missing but because of something is implemented in vain.
Although I don't know why it happens but if following method implemented in your code, that may cause popover not to dismiss by tapping anywhere else than UIBarButtonItem itself.
func prepareForPopoverPresentation(_ popoverPresentationController: UIPopoverPresentationController) {
popoverPresentationController.permittedArrowDirections = .any
popoverPresentationController.barButtonItem = UIBarButtonItem(customView: categoryButton)
}
Here's the rest of implementation I have made for popover:
extension SearchViewController:UIPopoverPresentationControllerDelegate {
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
}
func presentPopover(sender: UIButton) {
let popoverContentController = PopoverCategoryViewController()
let nav = UINavigationController(rootViewController: popoverContentController)
nav.modalPresentationStyle = UIModalPresentationStyle.popover
nav.isNavigationBarHidden = true
let popover = nav.popoverPresentationController
popover?.backgroundColor = ChaptifyColor.backgroundGray
popover?.delegate = self
popover?.sourceView = sender
popover?.sourceRect = CGRect(origin: CGPoint(x: 0, y: 0), size: CGSize(width: sender.bounds.width, height: sender.bounds.height))
popoverContentController.preferredContentSize = CGSize(width: 300, height: 300)
self.present(nav, animated: true, completion: nil)
}
}
