问题
I followed this UIPopoverPresentationController on iPhone doesn't produce popover but doesn't produce popover on iphone. Here is the code of viewcontroller
class ViewController:UIViewController,UIPopoverPresentationControllerDelegate{
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "second"{
let secondVC = segue.destination
let controller : UIPopoverPresentationController = secondVC.popoverPresentationController!
controller.delegate = self
}
}
/* Popover delegate method */
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.none
}
}
I am not able to show new viewcontroller using present as popover in iphone. (ios 10/xcode8)
After clicking on button secondViewController should popover on that button.

After using this delegate method it is producing popover on iphone.
func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle {
return UIModalPresentationStyle.none
}
