'UIActivityViewController on iPad

I have been using the code below to show a UIActivityViewController which worked fine when I was using Xcode 6, Swift 1.2 and iOS 8. However when I updated it shows the UIActivityViewController but it is completely blank without any of the sharing options. Do you have any suggestions?

if UIDevice.currentDevice().userInterfaceIdiom == .Pad {
        let textToShare = textViewOne.text

            let objectsToShare = [textToShare]
            let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

            let nav = UINavigationController(rootViewController: activityVC)
            nav.modalPresentationStyle = UIModalPresentationStyle.Popover
            let popover = nav.popoverPresentationController as UIPopoverPresentationController!

            popover.sourceView = self.view
            popover.sourceRect = sender.frame

            self.presentViewController(nav, animated: true, completion: nil)

    } else {
        let textToShare = textViewOne.text

        let objectsToShare = [textToShare]
        let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

        self.presentViewController(activityVC, animated: true, completion: nil)

    }

This has fixed it.

        let objectsToShare = [textToShare]
        let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
        activityVC.title = "Share One"
        activityVC.excludedActivityTypes = []

        activityVC.popoverPresentationController?.sourceView = self.view
        activityVC.popoverPresentationController?.sourceRect = sender.frame

        self.presentViewController(activityVC, animated: true, completion: nil)

in swift 3.0:

let objectsToShare = [textToShare]
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
activityVC.title = "Share One"
activityVC.excludedActivityTypes = []

activityVC.popoverPresentationController?.sourceView = self.view
activityVC.popoverPresentationController?.sourceRect = sender.frame

self.present(activityVC, animated: true, completion: nil)

I was struggling with the above suggestion with SWIFT 5 since:

activity.popoverPresentationController?.sourceRect = sender.frame

does NOT WORK in some cases, since sender is not available in scope. Try instead to set with a CGRECT, something like:

activityController.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.midX, y: self.view.bounds.midY,width: 0,height: 0)

I hope this helps some people.

Swift 4.0

    let shareText = "Hi"
    let activity = UIActivityViewController(activityItems: shareText, applicationActivities: nil)
    activity.excludedActivityTypes = []

    if UIDevice.current.userInterfaceIdiom == .pad {
        activity.popoverPresentationController?.sourceView = self.view
        activity.popoverPresentationController?.sourceRect = sender.frame
    }
    self.present(activity, animated: true, completion: nil)

I had sort of a different issue. I wanted the UIActivityViewController to stay in the center of the screen but when rotating the iPad it was off centered when in Landscape.

Landscape wrong:

The 2 fixes was to make the UIActivityViewController a class property and most importantly set its sourceRect in viewDidLayoutSubviews. Follow the 5 steps-

// 1. make the activityVC a class property
var activityVC: UIActivityViewController?

override func viewDidLayoutSubviews() {
        super.viewDidLayoutSubviews()

    if UIDevice.current.userInterfaceIdiom == .pad {
        // 2. set its sourceRect here. It's the same as in step 4           
        activityVC?.popoverPresentationController?.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
    }
}

// 3. present the UIActivityViewController
func presentActivityVC() {

    let objectsToShare = [textToShare]

    activityVC = nil
    activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)
    activityVC?.excludedActivityTypes = [.addToReadingList, .openInIBooks, .print]
    activityVC?.popoverPresentationController?.sourceView = self.view

    if UIDevice.current.userInterfaceIdiom == .phone {
        activityVC?.modalPresentationStyle = .overFullScreen
    }
        
    if UIDevice.current.userInterfaceIdiom == .pad {
        // 4. set its sourceRect here. It's the same as in step 2
        activityVC?.popoverPresentationController?.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
        activityVC?.popoverPresentationController?.permittedArrowDirections = []
    }

    present(activityVC!, animated: true, completion: nil)

    activityVC?.completionWithItemsHandler = { [weak self](activityType, completed:Bool, returnedItems:[Any]?, error: Error?) in
        if let error = error {
            print(error.localizedDescription)
            return
        }

        // 5. set the activityVC to nil after the user is done 
        DispatchQueue.main.async { [weak self] in
            self?.activityVC = nil
        }
    }
}

Now when rotating it's centered both in landscape and portrait.

Landscape correct:

Portrait:

best solve for iPad and iPhone try it

let urlstring = "https://apps.apple.com/ae/app/"
let text = "some text for your app"
let url = NSURL(string: urlstring)
let textToShare = [url!,text] as [Any]
let activityViewController = UIActivityViewController(activityItems: textToShare as [Any], applicationActivities: nil)
    
activityViewController.excludedActivityTypes = [ UIActivity.ActivityType.airDrop, UIActivity.ActivityType.postToFacebook ,UIActivity.ActivityType.postToFlickr,UIActivity.ActivityType.postToTwitter,UIActivity.ActivityType.postToVimeo,UIActivity.ActivityType.mail,UIActivity.ActivityType.addToReadingList]

activityViewController.popoverPresentationController?.sourceView = self.view
activityViewController.popoverPresentationController?.sourceRect = view.bounds
activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection.down
UIApplication.shared.windows.first?.rootViewController?.present(activityViewController, animated: true, completion: nil)

Solution 6:^[6]

if you want to attach the popover to the sender view's bounds, then the following code will work:

let vc = UIActivityViewController(activityItems: [url], applicationActivities: nil)
if UIDevice.current.userInterfaceIdiom == .pad {
  vc.popoverPresentationController?.sourceView = sender
  vc.popoverPresentationController?.sourceRect = CGRect(origin: CGPoint.zero, size: sender.frame.size)
}

sourceRect is defined in the coordinate space of the sourceView, thus we need to specify the origin of the sourceRect as CGPoint.zero rather than sender.frame.origin.

Solution 7:^[7]

We would need to set the sourceView and sourceRect both specially for iPad.

We may try below snippet

activityViewController.popoverPresentationController?.sourceView = sender.self
activityViewController.popoverPresentationController?.sourceRect = CGRect(x: self.view.bounds.minX + sender.frame.width/2, y: self.view.bounds.minY, width: 0, height: 0)
activityViewController.popoverPresentationController?.permittedArrowDirections = []

It would set the sourceView as sender's and sourceRect at center to the UI.

We are adding sender.frame.width/2 to x coordinate and removing the anchor arrow as well to get the pop-up exactly at center.
