I\'m trying to display a ViewController as a popover on an iPhone. I have already been through several answers on SO and the rest of the web but none have worked so far. I w
Add:
vc.popoverPresentationController?.delegate = self
just before the line:
present(vc, animated: true, completion: nil)
You are connecting delegate after presenting view. How it will return .none from delegate and show as popover. Use this :-
func clicked(_ sender: Any) {
let vc = UIViewController()
vc.view.backgroundColor = UIColor.blue
vc.modalPresentationStyle = .popover
vc.preferredContentSize = CGSize(width: 200, height: 200)
let ppc = vc.popoverPresentationController
ppc?.permittedArrowDirections = .any
ppc?.delegate = self
ppc?.barButtonItem = navigationItem.rightBarButtonItem
ppc?.sourceView = sender
present(vc, animated: true, completion: nil)
}
import UIKit
class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {
override func viewDidLoad() {
super.viewDidLoad()
navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .done, target: self, action: #selector(clicked(_:)))
}
func clicked(_ sender: Any) {
let vc = UIViewController()
vc.view.backgroundColor = UIColor.blue
vc.preferredContentSize = CGSize(width: 200, height: 200)
vc.modalPresentationStyle = .popover
let ppc = vc.popoverPresentationController
ppc?.permittedArrowDirections = .any
ppc?.delegate = self
ppc!.sourceView = sender as? UIView
ppc?.barButtonItem = navigationItem.rightBarButtonItem
present(vc, animated: true, completion: nil)
}
func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
return .none
}
}
The solutions above no longer work in recent iOS versions 12 and above. To get it working again, override -modalPresentationStyle
within the viewController to be presented as a popover and return UIModalPresentationPopover
.
Additionally provide a popoverPresentationController.delegate
, implement adaptivePresentationStyleForPresentationController:traitCollection:
and return UIModalPresentationNone
.
@interface PopoverViewController : UIViewController
@end
@implementation PopoverViewController
- (UIModalPresentationStyle)modalPresentationStyle
{
return UIModalPresentationPopover;
}
@end
@interface ViewController ()<UIPopoverPresentationControllerDelegate>
@end
@implementation ViewController
- (IBAction)openPopover:(id)sender
{
UIViewController* testVC = [[PopoverViewController alloc] init];
testVC.view.backgroundColor = UIColor.yellowColor;
UIPopoverPresentationController* popPresenter = [testVC popoverPresentationController];
popPresenter.permittedArrowDirections = UIPopoverArrowDirectionUp;
popPresenter.delegate = self;
popPresenter.sourceView = sender;
popPresenter.sourceRect = [sender bounds];
[self presentViewController:testVC animated:YES completion:^{}];
}
#pragma mark protocol (UIPopoverPresentationControllerDelegate)
- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller traitCollection:(UITraitCollection *)traitCollection
{
return UIModalPresentationNone;
}
@end
