I keep getting this error because I cannot correctly anchor my segue. I've tried a mixture of using Storyboards and coding.
I'm a newbie to iOS, so I've been unsuccessfully trying to solve this problem by looking at this solution, as well as Youtube videos. Any help would be greatly appreciated!
From my experience it is easier to just do this programatically and forget about the segue / storyboard all together.
This works in swift 2.0
func showPopOverBox(button:UIButton) {
let popoverViewController = self.storyboard?.instantiateViewControllerWithIdentifier("yourviewcontrollerstoryboardId") as UIViewController!
popoverViewController.modalPresentationStyle = .Popover
popoverViewController.preferredContentSize = CGSizeMake(600, 600)
let popoverPresentationViewController = popoverViewController.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = UIPopoverArrowDirection.Any
popoverPresentationViewController?.sourceView = button
popoverPresentationViewController?.sourceRect = button.bounds
presentViewController(popoverViewController, animated: true, completion: nil)
}
Here is the Swift 3.0 answer:
func showPopOverBox(button:UIButton)
{
let popoverViewController = self.storyboard?.instantiateViewController(withIdentifier: "yourviewcontrollerstoryboardId") UIViewController!
popoverViewController?.modalPresentationStyle = .popover
popoverViewController?.preferredContentSize = CGSize.init(width: 600, height: 600)
let popoverPresentationViewController = popoverViewController?.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = UIPopoverArrowDirection.up
popoverPresentationViewController?.sourceView = button
popoverPresentationViewController?.sourceRect = button.bounds
present(popoverViewController!, animated: true, completion: nil)
}

My project is entire in Storyboard, I have a UITableViewController embed in a NavigationController and on each cell I have a button to Share the Notice.
#IBAction func shareSheetButtonFeed(sender: AnyObject) {
let btnPos: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
let indexPath: NSIndexPath = self.tableView.indexPathForRowAtPoint(btnPos)!
passaValor = Int(indexPath.row)
let printtestess = (objects?[passaValor] as! PFObject)
let textToShare: AnyObject = (printtestess.objectForKey("subject")! as! String) + " - Cheque agora em:"
let myWebsite = NSURL(string:"http://www.mysite.com.br/")
let img: UIImage = UIImage(named: "myLogo-1024x1024")!
guard let url = myWebsite else {
print("nothing found")
return
}
self.navigationController?.setNavigationBarHidden(false, animated: true)
let shareItems:Array = [img, textToShare, url]
let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
The problem is, when I click in the button the shareSheet is presented, after I choose the Social Network, like Twitter or Facebook my previous NavigationBar dissapear.
I tried to solve the problem using this line, inside the button, and when I click again in the button the navBar reappear:
self.navigationController?.setNavigationBarHidden(false, animated: true)
So I tried to put this line inside the ViewWillAppear, but it did not work.
Obs: I'm using Auto-Layout
Thanks.
Try waiting until the share sheet is closed to show the navigation bar. To do so, set the completionWithItemsHandler property on UIActivityViewController.
activityViewController.completionWithItemsHandler = { _ in
self.navigationController?.setNavigationBarHidden(false, animated: true)
}
I want there to be a button in my app, that when it is pressed, this(See image below) Pops up. How do i do that? I don't want to create a custom sharing extion, i just want the default one? What code do i use? All the tutorials online are in objective-c. Please give an answer in swift.

Here is my code so far, but i get an error that UIBarButtonItem Is not convetable to UIVIew Why? The action is connected to a navigation bar button item?
#IBAction func ActionButton(sender: UIBarButtonItem) {
let firstActivityItem = "Text you want"
let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
// If you want to put an image
let image : UIImage = UIImage(named: "TALogo")!
let activityViewController : UIActivityViewController = UIActivityViewController(
activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
// This lines is for the popover you need to show in iPad
activityViewController.popoverPresentationController?.sourceView = (sender as! UIBarButtonItem)
// This line remove the arrow of the popover to show in iPad
activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.allZeros
activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
// Anything you want to exclude
activityViewController.excludedActivityTypes = [
UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo
]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
The way is using UIActivityViewController for example in the following way :
#IBAction func shareSheet(sender: AnyObject) {
let firstActivityItem = "Text you want"
let secondActivityItem : NSURL = NSURL(string: "http//:urlyouwant")!
// If you want to put an image
let image : UIImage = UIImage(named: "image.jpg")!
let activityViewController : UIActivityViewController = UIActivityViewController(
activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
// This lines is for the popover you need to show in iPad
activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
// This line remove the arrow of the popover to show in iPad
activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.allZeros
activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
// Anything you want to exclude
activityViewController.excludedActivityTypes = [
UIActivityTypePostToWeibo,
UIActivityTypePrint,
UIActivityTypeAssignToContact,
UIActivityTypeSaveToCameraRoll,
UIActivityTypeAddToReadingList,
UIActivityTypePostToFlickr,
UIActivityTypePostToVimeo,
UIActivityTypePostToTencentWeibo
]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
The above code works for both iPhone and iPad because in you set the new popoverPresentationController in iOS 8 it works for iPad too.
In the case of use an UIBarButtonItem you need to replace this line:
activityViewController.popoverPresentationController?.sourceView = (sender as! UIButton)
With this one:
activityViewController.popoverPresentationController?.barButtonItem = (sender as! UIBarButtonItem)
I hope this help you.
When a UIActivityViewController is called on the iPhone in this app, it works perfectly, but when called on a iPad, the app crashes. Below is the code I used:
func shareButtonPress() {
//when the share button is pressed, default share phrase is added, cropped image of highscore is added
var sharingItems = [AnyObject]()
var shareButtonHighscore = NSUserDefaults.standardUserDefaults().objectForKey("highscore") as Int!
sharingItems.append("Just hit \(shareButtonHighscore)! Beat it! #Swath")
UIGraphicsBeginImageContextWithOptions(UIScreen.mainScreen().bounds.size, false, 0);
self.view.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)
var image:UIImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
sharingItems.append(image)
let activityViewController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)
var barButtonItem: UIBarButtonItem! = UIBarButtonItem()
activityViewController.excludedActivityTypes = [UIActivityTypeCopyToPasteboard,UIActivityTypeAirDrop,UIActivityTypeAddToReadingList,UIActivityTypeAssignToContact,UIActivityTypePostToTencentWeibo,UIActivityTypePostToVimeo,UIActivityTypePrint,UIActivityTypeSaveToCameraRoll,UIActivityTypePostToWeibo]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
As you can see, I'm programming in Swift, in the SpriteKit Framework, and I don't understand why the app is crashing.
I'm receiving this error:
Terminating app due to uncaught exception 'NSGenericException', reason: 'UIPopoverPresentationController (<_UIAlertControllerActionSheetRegularPresentationController: 0x7fc7a874bd90>) should have a non-nil sourceView or barButtonItem set before the presentation occurs.'
What can I do to fix this problem?
Before presenting the UIActivityViewController, add in this line of code:
activityViewController.popoverPresentationController?.sourceView = self.view
This way, the view controller knows in which frame of the GameViewController to appear in.
If you read the error it says how to fix it, you need to set the barButtonItem or sourceView from which to present the popover from, in your case:
func shareButtonPress(pressedButton: UIBarButtonItem) {
...
activityViewController.popoverPresentationController.barButtonItem = pressedButton
self.presentViewController(activityViewController, animated: true, completion: nil)
}
Swift 5:
Check if the device is iPhone or iPad and based on that add a sourceView and present the activityController
let activity = UIActivityViewController(activityItems: [self], applicationActivities: nil)
if UIDevice.current.userInterfaceIdiom == .phone {
UIApplication.topViewController?.present(activity, animated: true, completion: nil)
} else {
activity.popoverPresentationController?.sourceView = UIApplication.topViewController!.view
UIApplication.topViewController?.present(activity, animated: true, completion: nil)
}
There are two option, the action came from a UIBarButtonitem or UIButton that is a UIView.
func shareButtonPress() {
...
if let actv = activityViewController.popoverPresentationController {
actv.barButtonItem = someBarButton // if it is a UIBarButtonItem
// Or if it is a view you can get the view rect
actv.sourceView = someView
// actv.sourceRect = someView.frame // you can also specify the CGRect
}
self.presentViewController(activityViewController, animated: true, completion: nil)
}
You may have to add a sender to your function like func shareButtonPress(sender: UIBarButtonItem) or func shareButtonPress(sender: UIButton)
I added for Swift 3:
activityViewController.popoverPresentationController?.sourceView = self.view
fixed my issue.
I am trying to get a popover working in swift.
The view i am trying to put into the popover is in its own separate xib.
The code to load is below
let view = OrganisationDetails()
view.modalPresentationStyle = .Popover
let popoverMenuViewController = view.popoverPresentationController
view.preferredContentSize = CGSizeMake(550,550)
popoverMenuViewController?.permittedArrowDirections = .Any
popoverMenuViewController?.delegate = self
popoverMenuViewController?.sourceView = sender
popoverMenuViewController?.sourceRect = CGRect(x: 1, y: 1, width: 60, height: 60)
presentViewController(view, animated: true, completion: nil)
What is happening atm is the popover is loading totally blank and not displaying the view.
Any ideas what I'm doing wrong
Thanks
Actually it is much simpler than that. In the storyboard you should make the viewcontroller you want to use as popover and make a viewcontroller class for it as usual. Make a segue as shown below from the object you want to open the popover, in this case the UIBarButton named "Config".
In the "mother viewcontroller" implement the "UIPopoverPresentationControllerDelegate" and the delegate method:
func popoverPresentationControllerDidDismissPopover(popoverPresentationController: UIPopoverPresentationController) {
//do som stuff from the popover
}
Override the "prepareForSeque" method like this:
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
//segue for the popover configuration window
if segue.identifier == "yourSegueIdentifierForPopOver" {
if let controller = segue.destinationViewController as? UIViewController {
controller.popoverPresentationController!.delegate = self
controller.preferredContentSize = CGSize(width: 320, height: 186)
}
}
}
And your done. And you can now treat the popover view as any other view, ie. add fields and what not!
This is how I do it
//MARK:idPopupFileTable
let popoverVC = storyboard?.instantiateViewControllerWithIdentifier("idPopupFileTable") as UIViewController
popoverVC.modalPresentationStyle = .Popover
popoverVC.preferredContentSize = CGSizeMake(300, 200)
if let popoverController = popoverVC.popoverPresentationController {
popoverController.sourceView = sender
popoverController.sourceRect = sender.bounds
popoverController.permittedArrowDirections = .Any
popoverController.delegate = self
}
presentViewController(popoverVC, animated: true, completion: nil)
}
I'm having some trouble getting a UIPopover to appear using swift. The code that is commented out works fine in Objective-C, but doesn't work using Swift. When I tap the + in my view controller I do get the "click" in my debugger, however no popover appears.
class PlayerInformationTableViewController: UITableViewController, NSFetchedResultsControllerDelegate, UIPopoverControllerDelegate {
#IBOutlet weak var addBarButtonItem: UIBarButtonItem!
var playerInformationViewController = PlayerInformationViewController()
var popover:UIPopoverController? = nil
override func viewDidLoad() {
super.viewDidLoad()
/*
//setup the popover
_cuesPopoverViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"CuesPopoverViewController"];
self.cuesPopover = [[UIPopoverController alloc] initWithContentViewController:_cuesPopoverViewController];
self.cuesPopover.popoverContentSize = CGSizeMake(540, 300);
self.cuesPopover.delegate = self;
*/
playerInformationViewController.storyboard?.instantiateViewControllerWithIdentifier("PlayerInformationViewController")
popover?.contentViewController = playerInformationViewController
popover?.popoverContentSize = CGSizeMake(300, 300)
popover?.delegate = self
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem()
}
#IBAction func addPopover(sender: AnyObject) {
println("Click")
popover?.presentPopoverFromBarButtonItem(addBarButtonItem, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
}
Solution
override func viewDidLoad() {
super.viewDidLoad()
}
#IBAction func addPopover(sender: AnyObject) {
var popoverViewController = self.storyboard?.instantiateViewControllerWithIdentifier("PlayerInformationViewController") as UIViewController
popoverViewController.modalPresentationStyle = .Popover
popoverViewController.preferredContentSize = CGSizeMake(450, 450)
let popoverPresentationViewController = popoverViewController.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = .Any
popoverPresentationViewController?.delegate = self
popoverPresentationViewController?.barButtonItem = sender as UIBarButtonItem
presentViewController(popoverViewController, animated: true, completion: nil)
}
Here is a simple example for iOS 8. Popover are presented using adaptivity apis in iOS 8.
class PlayerInformationTableViewController: UITableViewController, UIPopoverPresentationControllerDelegate, NSFetchedResultsControllerDelegate{
...
#IBAction func addPopover(sender: UIBarButtonItem){
let playerInformationViewController = PlayerInformationViewController()
playerInformationViewController.modalPresentationStyle = .Popover
playerInformationViewController.preferredContentSize = CGSizeMake(300, 300)
let popoverPresentationViewController = playerInformationViewController.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = .Any
popoverPresentationViewController?.delegate = self
popoverPresentationController?.barButtonItem = sender
presentViewController(playerInformationViewController, animated: true, completion: nil)
}
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController!) -> UIModalPresentationStyle{
return .None
}
}
Display Popover with contentView from xib
func showPopover(sender: AnyObject) {
let contentViewController = UINib(nibName: "ContentVC", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as ContentVC
contentViewController.modalPresentationStyle = UIModalPresentationStyle.Popover
var detailPopover: UIPopoverPresentationController = contentViewController.popoverPresentationController!
detailPopover.delegate = self
detailPopover.barButtonItem = sender as UIBarButtonItem
detailPopover.permittedArrowDirections = UIPopoverArrowDirection.Any
presentViewController(contentViewController,
animated: true, completion:nil)
}
Next allows to make not full screen PopoverView on iPhone
for this do not forget to inherit MainViewController: UIPopoverPresentationControllerDelegate and set delegate to PopoverView
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController!) -> UIModalPresentationStyle
{
return .None
}
It looks like your popover is nil. Where are you assigning/instantiating it?
Try changing this:
popover?.presentPopoverFromBarButtonItem(addBarButtonItem, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
To this:
if let pop = popover {
pop.presentPopoverFromBarButtonItem(addBarButtonItem, permittedArrowDirections: UIPopoverArrowDirection.Any, animated: true)
} else {
NSLog("Error: Popover was nil")
}
I imagine you'll see that error message in your console. In the .XIB for your PlayerInformationTableViewController, do you have a UIPopoverController?
If so, you probably need to ensure that the var popover is either (1) being manually instantiated in your awakeFromNib, or that it's an #IBOutlet and is being connected properly.
Alternatively, can you simply use the popover already present in your playerInformationViewController?
