글쎄요. 보세요. StoryBoard에서 ViewController를 만들었습니다. PopOverViewController 클래스와 연결됩니다.

import UIKit

class PopOverViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        self.preferredContentSize = CGSizeMake(200, 200)
        self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .Done, target: self, action: "dismiss:")
    }
    func dismiss(sender: AnyObject) {
        self.dismissViewControllerAnimated(true, completion: nil)
    }
}      

ViewController를 참조하십시오.

//  ViewController.swift

import UIKit

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate
{
    func showPopover(base: UIView)
    {
        if let viewController = self.storyboard?.instantiateViewControllerWithIdentifier("popover") as? PopOverViewController {

            let navController = UINavigationController(rootViewController: viewController)
            navController.modalPresentationStyle = .Popover

            if let pctrl = navController.popoverPresentationController {
                pctrl.delegate = self

                pctrl.sourceView = base
                pctrl.sourceRect = base.bounds

                self.presentViewController(navController, animated: true, completion: nil)
            }
        }
    }
    override func viewDidLoad(){
        super.viewDidLoad()
    }
    @IBAction func onShow(sender: UIButton)
    {
        self.showPopover(sender)
    }
    func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
        return .None
    }
}  

참고 : func showPopover (base : UIView) 메서드는 ViewDidLoad 앞에 배치해야합니다. 도움이 되길 바랍니다!

- (IBAction)onclickPopover:(id)sender {
UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];
UIViewController *viewController = [sb instantiateViewControllerWithIdentifier:@"popover"];

viewController.modalPresentationStyle = UIModalPresentationPopover;
viewController.popoverPresentationController.sourceView = self.popOverBtn;
viewController.popoverPresentationController.sourceRect = self.popOverBtn.bounds;
viewController.popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirectionAny;
[self presentViewController:viewController animated:YES completion:nil]; }

-(void) popoverstart
{
    ViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"PopoverView"];
    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:controller];
    nav.modalPresentationStyle = UIModalPresentationPopover;
    UIPopoverPresentationController *popover = nav.popoverPresentationController;
    controller.preferredContentSize = CGSizeMake(300, 200);
    popover.delegate = self;
    popover.sourceView = self.view;
    popover.sourceRect = CGRectMake(100, 100, 0, 0);
    popover.permittedArrowDirections = UIPopoverArrowDirectionAny;
    [self presentViewController:nav animated:YES completion:nil];
}

-(UIModalPresentationStyle) adaptivePresentationStyleForPresentationController: (UIPresentationController * ) controller
{
    return UIModalPresentationNone;
}
