Popover in Swift 3 on iPhone iOS

Popover in swift 3 on iphone ios

Change your delegate method to:

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

Popover on iPhone (Swift 3) from Programmatically Created Button

You can check out the answer and library for your references. If the GroupSetsPopoverController is your popover viewcontroller, you can do something like this:

init(for sender: UIView)) {
    super.init(nibName: nil, bundle: nil)

    modalPresentationStyle = .popover
    guard let pop = popoverPresentationController else { return }
    pop.sourceView = sender
    pop.sourceRect = sender.bounds
    pop.delegate = self
}

how to use popover controller in iPhone

Set yourself as the popover view controller's delegate before presenting it, and implement the delegate method adaptivePresentationStyle(for:traitCollection:) to return .none. This will cause the popover to stop adapting on iPhone as a fullscreen presented view controller and turn into an actual popover just like on the iPad.

This is a complete working example that presents the popover in response to a button tap:

class ViewController: UIViewController {
    @IBAction func doButton(_ sender: Any) {
        let vc = MyPopoverViewController()
        vc.preferredContentSize = CGSize(400,500)
        vc.modalPresentationStyle = .popover
        if let pres = vc.presentationController {
            pres.delegate = self
        }
        self.present(vc, animated: true)
        if let pop = vc.popoverPresentationController {
            pop.sourceView = (sender as! UIView)
            pop.sourceRect = (sender as! UIView).bounds
        }
    }
}
extension ViewController : UIPopoverPresentationControllerDelegate {
    func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle {
        return .none
    }
}

Popover presentation style on iPhone devices - possible any more?

I have created one custom class with storyboard inside that connect
outlet of button and implemented below code.

import UIKit
class PopOverViewController: UIViewController {

    @IBOutlet weak var button: UIButton!
    override func viewDidLoad() {
        super.viewDidLoad()
        button.backgroundColor = UIColor.purple
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    //Updating the popover size
    override var preferredContentSize: CGSize {
        get {
            let size = CGSize(width: 80, height: 60)
            return size
        }
        set {
            super.preferredContentSize = newValue
        }
    }


    //Setup the ViewController for popover presentation
    func updatePopOverViewController(_ button: UIButton?, with delegate: AnyObject?) {
        guard let button = button else { return }
        modalPresentationStyle = .popover
        popoverPresentationController?.permittedArrowDirections = [.any]
        popoverPresentationController?.backgroundColor = UIColor.purple
        popoverPresentationController?.sourceView = button
        popoverPresentationController?.sourceRect = button.bounds
        popoverPresentationController?.delegate = delegate
    }

}

And then Inside ViewController implemented one function to show
popOver on iphone

func showPopOver(button: UIButton!) {
 let viewController = PopOverViewController()
 viewController.updatePopOverViewController(button, with: self)
  present(viewController, animated: true, completion: nil)
}

Note:- Tested and this should work on Portrait as well Landscape mode

Swift 3: UISearchBar in Popover ViewController shows up wider than expected (on iPad)

Well this was an interesting lesson in debugging UI issues.

I believe this was ultimately caused by the ViewController being set to size inferred and size fixed. On different iPad screen sizes (9.7" vs 12.9").

To resolve this I set the frame width of the search bar to the tableview below it. I'm not sure why the searchbarview size changed width since its constrained to leading and trailing edges (superview).

        if UIDevice.current.userInterfaceIdiom == .pad {
        self.resultSearchController.searchBar.frame = CGRect(x: 0, y: 0, width: Int(tableView.frame.width), height: 44)
    }

Although this works it has the same issue if split view is used (for widths where a popover has room to display).

Further suggestions are welcome but this is a good start.

---Edit---

Unchecking "Resize View from NIB" under layout in the ViewController as well as setting size to Freeform and declaring a constant width resolved the issue of the VC resizing on iPad. From there I just set the frame of the search bar in viewDidLoad as follows:

    if UIDevice.current.userInterfaceIdiom == .pad {
        self.resultSearchController.searchBar.frame = CGRect(x: 0, y: 0, width: 375, height: 44)
    }

Seems to work for all devices regardless of split view or not. There probably is a better way to do this without detecting iPads. Im thinking I'm missing a setting in Interface Builder.

How to present a UIViewController as a popover in Swift programmatically on iPhone

You can't do this in iPhone with portrait mode with this code ... you can check popover section in apple doc here..

It suggests that:

In iOS 8 and later, you use a UIPopoverPresentationController to present a popover. UIPopoverPresentationController defines a delegate that lets you adjust the display style of your popover content to suit the current display environment. For example, in a horizontally regular environment, your content can display inside a popover; in a horizontally compact environment, your content can display in a full-screen modal view.

And as I said, if you can check in iPad, your content can display inside a popover.

How to create popover in iPhone app?

You could make a UIView with some custom artwork and display it with an animation on top of your view as a "popover" with some buttons like so:

UIView *customView = [[UIView alloc] initWithFrame:CGRectMake(25, 25, 100, 50)]; //<- change to where you want it to show.

//Set the customView properties
customView.alpha = 0.0;
customView.layer.cornerRadius = 5;
customView.layer.borderWidth = 1.5f;
customView.layer.masksToBounds = YES;

//Add the customView to the current view
[self.view addSubview:customView];

//Display the customView with animation
[UIView animateWithDuration:0.4 animations:^{
    [customView setAlpha:1.0];
} completion:^(BOOL finished) {}];

Don't forget to #import <QuartzCore/QuartzCore.h>, if you want to use the customView.layer.

Present a popover from an arbitrary anchor point in Swift

Updated for Swift 3

In the storyboard, add a view controller that you would like to be the popover. Set the Storyboard ID to be "popoverId".

Also add a button to your main view controller and hook up the IBAction to the following code.

import UIKit
class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {

    @IBAction func buttonTap(sender: UIButton) {

        // get a reference to the view controller for the popover
        let popController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "popoverId")

        // set the presentation style
        popController.modalPresentationStyle = UIModalPresentationStyle.popover

        // set up the popover presentation controller
        popController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.up
        popController.popoverPresentationController?.delegate = self
        popController.popoverPresentationController?.sourceView = sender // button
        popController.popoverPresentationController?.sourceRect = sender.bounds

        // present the popover
        self.present(popController, animated: true, completion: nil)
    }

    // UIPopoverPresentationControllerDelegate method
    func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
        // Force popover style
        return UIModalPresentationStyle.none
    }
}

Setting the sourceView and sourceRect is what allows you to choose an arbitrary point to display the popover.

That's it. Now it should like something like this when the button is tapped.

Thanks to this article for help.

UIPopoverPresentationController on iPhone doesn't produce popover

Steps:

A) Link your UIButton to the popover's view controller using the Present As Popover segue type. I actually had to create a new project to get this to appear but it's probably something to do with the base SDK.

B) Make the View Controller containing the UIButton conform to the <UIPopoverPresentationControllerDelegate>. E.g. In your MyViewController.m file add:

@interface MyViewController () <UIPopoverPresentationControllerDelegate>

C) Add the method below to the View Controller containing the UIButton:

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {

    return UIModalPresentationNone;
}

D) Add the following into your prepareForSegue:sender: replacing your segue.identifier check:

if ([segue.identifier isEqualToString:@"CatSelectSegue"]) {
    UIViewController *dvc = segue.destinationViewController;
    UIPopoverPresentationController *controller = dvc.popoverPresentationController;
    if (controller) {
        controller.delegate = self;
    }
}

Code tested and proof it works:

Edit: My test app TPOPViewController.m file where the magic happens:

#import "TPOPViewController.h"

@interface TPOPViewController () <UIPopoverPresentationControllerDelegate>//, UIAdaptivePresentationControllerDelegate>

@end

@implementation TPOPViewController

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

    NSString *identifier = segue.identifier;
    if ([identifier isEqualToString:@"popover"]) {
        UIViewController *dvc = segue.destinationViewController;
        UIPopoverPresentationController *ppc = dvc.popoverPresentationController;
        if (ppc) {
            if ([sender isKindOfClass:[UIButton class]]) { // Assumes the popover is being triggered by a UIButton
                ppc.sourceView = (UIButton *)sender;
                ppc.sourceRect = [(UIButton *)sender bounds];
            }
            ppc.delegate = self;
        }
    }
}

- (UIModalPresentationStyle)adaptivePresentationStyleForPresentationController:(UIPresentationController *)controller {

    return UIModalPresentationNone;
}

@end

My test storyboard as well:
