iOS 8 iPhone의 UIPopoverPresentationController

UIPopoverPresentationControlleriPhone에서 팝 오버를 표시하는 데 사용할 수 있는지 아는 사람이 있습니까? Apple이 iPad 및 iPhone 용으로 더욱 통합 된 프레젠테이션 컨트롤러를 만들기 위해 iOS 8에이 기능을 추가했는지 궁금합니다.

베타에서 질문 / 답변이 가능한지 확실하지 않습니다. 이 경우 제거하겠습니다.

를 통해 제공 UIModalPresentationFullScreen되는 adaptivePresentationStyleForPresentationController:방법을 사용 하여 기본 적응 동작 ( 예 : iPhone과 같은 컴팩트 수평 환경)을 재정의 할 수 있습니다 UIPopoverPresentationController.delegate.

UIPresentationController이 방법을 사용하여 사용할 새 프레젠테이션 스타일을 요청합니다. 귀하의 경우에는 단순히 반환 UIModalPresentationNone하면 UIPopoverPresentationController을 전체 화면 대신 팝 오버로 렌더링합니다.

다음은 스토리 보드의 segue 설정을 사용하여 a UIBarButtonItem에서 " present modally " 까지 팝 오버의 예입니다 .UIViewController

class SomeViewController: UIViewController, UIPopoverPresentationControllerDelegate {

    // override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) { // swift < 3.0
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == "PopoverSegue" {
            if let controller = segue.destinationViewController as? UIViewController {
                controller.popoverPresentationController.delegate = self
                controller.preferredContentSize = CGSize(width: 320, height: 186)                
            }
        }
    }

    // MARK: UIPopoverPresentationControllerDelegate

    //func adaptivePresentationStyleForPresentationController(controller: UIPresentationController!) -> UIModalPresentationStyle { // swift < 3.0
    func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
        // Return no adaptive presentation style, use default presentation behaviour
        return .None
    }
}

이 트릭은 WWDC 2014 세션 214 "View Controller Advancement in iOS8" (36:30) 에서 언급되었습니다.

누군가 코드로만 팝 오버를 표시하려는 경우 다음 접근 방식을 사용할 수 있습니다.

목표-C

의 속성 선언 UIPopoverPresentationController:

@property(nonatomic,retain)UIPopoverPresentationController *dateTimePopover8;

다음 메소드를 사용하여 UIButton에서 팝 오버를 표시하십시오.

- (IBAction)btnSelectDatePressed:(id)sender
{
    UINavigationController *destNav = [[UINavigationController alloc] initWithRootViewController:dateVC];/*Here dateVC is controller you want to show in popover*/
    dateVC.preferredContentSize = CGSizeMake(280,200);
    destNav.modalPresentationStyle = UIModalPresentationPopover;
    _dateTimePopover8 = destNav.popoverPresentationController;
    _dateTimePopover8.delegate = self;
    _dateTimePopover8.sourceView = self.view;
    _dateTimePopover8.sourceRect = sender.frame;
    destNav.navigationBarHidden = YES;
    [self presentViewController:destNav animated:YES completion:nil];
}

다음 메서드를 사용하여 UIBarButtonItem에서 팝 오버를 표시합니다.

- (IBAction)btnSelectDatePressed:(id)sender
{
    UINavigationController *destNav = [[UINavigationController alloc] initWithRootViewController:dateVC];/*Here dateVC is controller you want to show in popover*/
    dateVC.preferredContentSize = CGSizeMake(280,200);
    destNav.modalPresentationStyle = UIModalPresentationPopover;
    _dateTimePopover8 = destNav.popoverPresentationController;
    _dateTimePopover8.delegate = self;
    _dateTimePopover8.sourceView = self.view;
     CGRect frame = [[sender valueForKey:@"view"] frame];
    frame.origin.y = frame.origin.y+20;
    _dateTimePopover8.sourceRect = frame;
    destNav.navigationBarHidden = YES;
    [self presentViewController:destNav animated:YES completion:nil];
}

뷰 컨트롤러에서도이 델리게이트 메서드를 구현하십시오.

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

이 팝 오버를 닫으려면 뷰 컨트롤러를 닫으면됩니다. 다음은 뷰 컨트롤러를 닫는 코드입니다.

-(void)hideIOS8PopOver
{
    [self dismissViewControllerAnimated:YES completion:nil];
}

빠른

다음 방법을 사용하여 UIButon에서 팝 오버를 표시하십시오.

func filterBooks(sender: UIButon)
    {
        let filterVC =  FilterDistanceViewController(nibName: "FilterDistanceViewController", bundle: nil)
        var filterDistanceViewController = UINavigationController(rootViewController: filterVC)
        filterDistanceViewController.preferredContentSize = CGSizeMake(300, 205)
        let popoverPresentationViewController = filterDistanceViewController.popoverPresentationController
        popoverPresentationViewController?.permittedArrowDirections = .Any
        popoverPresentationViewController?.delegate = self
        popoverPresentationController?.barButtonItem = self.navigationItem.rightBarButtonItem
        popoverPresentationViewController!.sourceView = self.view;
        popoverPresentationViewController!.sourceRect = sender.frame

        filterDistanceViewController.modalPresentationStyle = UIModalPresentationStyle.Popover
        filterDistanceViewController.navigationBarHidden = true
        self.presentViewController(filterDistanceViewController, animated: true, completion: nil)
    }

다음 메서드를 사용하여 UIBarButtonItem에서 팝 오버를 표시합니다.

func filterBooks(sender: UIBarButtonItem)
    {
        let filterVC =  FilterDistanceViewController(nibName: "FilterDistanceViewController", bundle: nil)
        var filterDistanceViewController = UINavigationController(rootViewController: filterVC)
        filterDistanceViewController.preferredContentSize = CGSizeMake(300, 205)
        let popoverPresentationViewController = filterDistanceViewController.popoverPresentationController
        popoverPresentationViewController?.permittedArrowDirections = .Any
        popoverPresentationViewController?.delegate = self
        popoverPresentationController?.barButtonItem = self.navigationItem.rightBarButtonItem
        popoverPresentationViewController!.sourceView = self.view;
        var frame:CGRect = sender.valueForKey("view")!.frame
        frame.origin.y = frame.origin.y+20
        popoverPresentationViewController!.sourceRect = frame

        filterDistanceViewController.modalPresentationStyle = UIModalPresentationStyle.Popover
        filterDistanceViewController.navigationBarHidden = true
        self.presentViewController(filterDistanceViewController, animated: true, completion: nil)
    }

뷰 컨트롤러에서도이 델리게이트 메서드를 구현하십시오.

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle{
        return .None
    }

Please make sure to add delegate UIPopoverPresentationControllerDelegate in .h/.m/.swift file

PROBLEM: iPhone popover displays fullscreen and does not respect preferredContentSize value.

SOLUTION: Contrary to what Apple suggests in the UIPopoverPresentationController Class reference, presenting the view controller after getting a reference to the popover presentation controller and configuring it.

// Get the popover presentation controller and configure it.
//...

// Present the view controller using the popover style.
[self presentViewController:myPopoverViewController animated: YES completion: nil]; 

---

I've found some workaround.

On Xcode6.1, use presentationController.delegate instead of popoverPresentationController.delegate.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier compare:@"showPopOver"] == NSOrderedSame) {
        UINavigationController * nvc = segue.destinationViewController;
        UIPresentationController * pc = nvc.presentationController;
        pc.delegate = self;
    }
}

#pragma mark == UIPopoverPresentationControllerDelegate ==
- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller
{
    return UIModalPresentationNone;
}

In WWDC 2014 "View Controller Advancements in iOS8", below codes can show popover on iPhone.

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{

    UINavigationController * nvc = segue.destinationViewController;
    UIPopoverPresentationController * pvc = nvc.popoverPresentationController;
    pvc.delegate = self;
}

#pragma mark == UIPopoverPresentationControllerDelegate ==
- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller
{
    return UIModalPresentationNone;
}

But On Xcode 6.1, these codes shows FullScreen presentation... (nvc.popoverPresentationController is nil)

I doubt it might be an Apple's bug.

Make sure to implement UIAdaptivePresentationControllerDelegate

like this:

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

If you don't want full-screen popovers

In iOS 8.3 and later, use the following syntax in the UIPopoverPresentationControllerDelegate protocol to override your popup's UIModalPresentationStyle.

func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
    return .none
}

---

add these two methods in your WEBVIEW class. and add

-(void) prepareForSegue: (UIStoryboardSegue * ) segue sender: (id) sender {
    // Assuming you've hooked this all up in a Storyboard with a popover presentation style
    if ([segue.identifier isEqualToString: @"showPopover"]) {
        UINavigationController * destNav = segue.destinationViewController;
        pop = destNav.viewControllers.firstObject;
        // This is the important part
        UIPopoverPresentationController * popPC = destNav.popoverPresentationController;
        popPC.delegate = self;
    }
}

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