UIPopoverPresentationController displaying popover as full screen

Question

I am trying to use UIPopoverPresentationController to display a popover that doesn\'t take up the whole screen. I\'ve followed many different tutor

Answer 1

The accepted answer is correct. For completeness, see Adapting Presented View Controllers to a New Style in the Apple docs:

Use the delegate’s adaptivePresentationStyleForPresentationController: method to specify a different presentation style than the default. When transitioning to a compact environment, the only supported styles are the two full-screen styles or UIModalPresentationNone. Returning UIModalPresentationNone tells the presentation controller to ignore the compact environment and continue using the previous presentation style. In the case of a popover, ignoring the change gives you the same iPad-like popover behavior on all devices.

Make sure that the required configurations from Presenting a View Controller in a Popover are met:

After setting the modal presentation style [of the presented view controller] to UIModalPresentationPopover, configure the following popover-related attributes:

• Set the preferredContentSize property of your view controller to the desired size.
• Set the popover anchor point using the associated UIPopoverPresentationController object, which is accessible from the view controller’s popoverPresentationController property.
• Set only one of the following:
  • Set the barButtonItem property to a bar button item.
  • Set the sourceView and sourceRect properties to a specific region in one of your views.

For Swift3/IOS10, looks like we need to do some thing like

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

Adding this answer, in case, someone runs into this problem as i did when migrating to swift3/IOS10

Answer 3

In iPhone, you should add the following in order to present a popover.

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

iOS 12 / Swift 4

There's also the possibility to show the popover on IPhone's as fullscreen and on IPad's as a popover.

Just return .popover for adaptivePresentationStyle():

func adaptivePresentationStyle(for controller: UIPresentationController) -> UIModalPresentationStyle {
    return .popover
}

and set the popover-configuration like @mourodrigo did:

dialog.modalPresentationStyle = .popover
dialog.popoverPresentationController?.delegate = self
dialog.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
dialog.popoverPresentationController?.sourceView = view
dialog.popoverPresentationController?.sourceRect = view.frame

Answer 5

For Swift3+/IOS10+, when dealing with iPhone:

You must add UIPopoverPresentationControllerDelegate the delegate at:

class YourClass:  UIViewController, UIPopoverPresentationControllerDelegate { ...

Then implement in this same parent class (which will show the popover) the method below.

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

And then set the popover configuration below:

myPopover.modalPresentationStyle = .popover
myPopover.popoverPresentationController?.sourceRect = VIEWTOPOINTTHEARROW.frame
myPopover.popoverPresentationController?.sourceView = self.view
myPopover.popoverPresentationController?.delegate = self

Also you may set some configuration for the popover class

 class MyPopover: UIViewController {

 override func viewDidLoad() {
    super.viewDidLoad()
    //popover size
    self.preferredContentSize = CGSize(width: 320, height: 200) 
    //sets the arrow of the popover to same color of background
    self.popoverPresentationController?.backgroundColor = self.view.backgroundColor
   }

 }

objective-c version:

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