Please don't mark duplicate already seen iOS11: UIActivityViewController not successfully sharing UIImage to 3rd party apps
So I am trying to share Image + URL with UIActivityViewController .
However when tap on facebook it only show URL, Image is not showingup
Here is my code
#IBAction func btnShareTapped(_ sender: UIButton) {
if let image = self.imgBackground.image, let jpgImage = UIImageJPEGRepresentation(image, 0.8) {
let shareItems:Array = [jpgImage,URL(string: "https://www.facebook.com")] as [Any]
let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: shareItems, applicationActivities: nil)
activityViewController.excludedActivityTypes = [UIActivityType.print, UIActivityType.postToWeibo, UIActivityType.copyToPasteboard, UIActivityType.addToReadingList, UIActivityType.postToVimeo]
self.present(activityViewController, animated: true, completion: nil)
DispatchQueue.main.async {
self.present(activityViewController, animated: true, completion: nil);
}
}
}
If I remove URL then I can able to share image,
Only URL Visible for sharing
Is there any workaround to share Image with URL or any text ?
it's impossible to share images and URL at the same time currently

I have an iOS App similar to Photos App from Apple, which also has a ‘Share’ button for sharing photo, which worked well before. The code is as follows (for simplicity, I changed the sharing content to a string):
#objc func shareButtonTapped()
{
let vc = UIActivityViewController(activityItems: ["www.apple.com"], applicationActivities: nil);
if let pop = vc.popoverPresentationController
{
pop.sourceView = someView;
pop.sourceRect = shareButton.frame;
}
self.present(vc, animated: true, completion: nil);
}
But when my iPhone was upgraded to iOS 15, the UIActivityViewController that is showed up was invisible. I attach an operation video:
enter link description here
Observe carefully, in fact, UIActivityViewController has a pop-up, but it has become almost transparent.
Then, I added a statement to deliberately set the background color of its view:
#objc func shareButtonTapped()
{
let vc = UIActivityViewController(activityItems: ["www.apple.com"], applicationActivities: nil);
vc.view.backgroundColor = UIColor.systemBackground;
if let pop = vc.popoverPresentationController
{
pop.sourceView = someView;
pop.sourceRect = shareButton.frame;
}
self.present(vc, animated: true, completion: nil);
}
The operation video is as follows:
enter link description here
This code is very simple and very standard. I don't know why this happens?
Hope someone can help. Thanks in advance!
In fact, I define the shareButton within a class derived from UICollectionViewCell:
class AssetPreviewCell: UICollectionViewCell, UIScrollViewDelegate, PHLiveViewDelegate, UINavigationControllerDelegate
{
//....
}
And the complete code is:
#objc func shareButtonTapped()
{
guard let svc = self.findViewController() else { return }
let vc = UIActivityViewController(activityItems: ["www.apple.com"], applicationActivities: nil);
if let pop = vc.popoverPresentationController
{
pop.sourceView = someView;
pop.sourceRect = shareButton.frame;
}
svc.present(vc, animated: true, completion: nil);
}
The func findViewController() is the method from enter link description here
Edit:
And I have an 'Albums' button next to the 'Share' button. When the 'Albums' button is tapped, I present another view controller for add current photo to albums or remove current photo from albums according user select or deselect. This view controller is presented quiet normally. The operation video is on enter link description here . So I think the problem is just from UIActivityViewController or something else.
I find the answer. The problem is caused because I overrided the viewDidLoad function of UIActivityViewController for some reason:
override open func viewDidLoad()
{
super.viewDidLoad();
a_var += 1;
}
This cause problem on iOS15 while works well on iOS14 or iOS13.
Now I override the viewDidAppear(_) instead and the problem dissappears:
override open func viewDidAppear(_ animated: Bool)
{
super.viewDidAppear(animated);
a_var += 1;
}
ps: #mczmma is another account of mine. This account is restricted to ask question. I don't know the reason.
What worked for me in my use case was just to change the sourceView from
let shareAll = [textView.text]
let activityViewController = UIActivityViewController(activityItems: shareAll, applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
self.present(activityViewController, animated: true, completion: nil)
to
let shareAll = [textView.text]
let activityViewController = UIActivityViewController(activityItems: shareAll, applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = textView
self.present(activityViewController, animated: true, completion: nil)
So that on iPad the share shows above the textView, and it just works normally on iPhone.
When I share a webpage (example: apple.com) from Safari to the Messages app, it shares a rich preview in a custom UI element with an image and the page's title and URL.
However, when I try to share a URL to Messages from my own code (even if it's one that works from Safari like apple.com), it just shares the URL as plain text. How can I get the same behavior as Safari when link sharing to Messages?
Here is my code that creates and presents the UIActivityViewController that shares the URL:
extension UIViewController {
func shareUrl(url: URL) {
let objectsToShare: Array<NSObject> = [url as NSObject]
let activityVC = UIActivityViewController(activityItems: objectsToShare,
applicationActivities: nil)
present(activityVC, animated: true)
}
}
let items = [URL(string: "https://www.apple.com")!]
let ac = UIActivityViewController(activityItems: items, applicationActivities: nil)
present(ac, animated: true)

I am trying to share both image and text in swift. but when i choose to share via facebook, messenger or whatsapp it only gives text (image is not shared). I am using UIActivityViewController for sharing.
here is my code:
func displayShareSheet(latitude:NSString?, longitude:NSString?, image:UIImage?, address:NSString? ) {
let activityViewController = UIActivityViewController(activityItems: [(latitude as NSString?)!, (longitude as NSString?)!, (image as UIImage?)!, (address as NSString?)!], applicationActivities: nil)
presentViewController(activityViewController, animated: true, completion: {}
)
}
Below is UIActivityViewController code is working for me. also attached screen shot for both the methods.
func shareImage() {
let img = UIImage(named: "SoSampleImage")
let messageStr = "Ketan SO"
let activityViewController:UIActivityViewController = UIActivityViewController(activityItems: [img!, messageStr], applicationActivities: nil)
activityViewController.excludedActivityTypes = [UIActivityTypePrint, UIActivityTypePostToWeibo, UIActivityTypeCopyToPasteboard, UIActivityTypeAddToReadingList, UIActivityTypePostToVimeo]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
Screen shot for UIActivityViewController example :
Alternative Using SLComposeViewController :
func share(){
let img = UIImage(named: "SoSampleImage")
let composeSheet = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
composeSheet.setInitialText("Hello, Ketan!")
composeSheet.addImage(img)
self.presentViewController(composeSheet, animated: true, completion: nil)
}

Hope it will help you..
Do let me know if you have any query.
Try this This is working for me!!!
#IBAction func btnExport(sender: AnyObject)
{
print("Export")
let someText:String = "Hello want to share text also"
let objectsToShare:UIImage = self.imgView.image!
let sharedObjects:[AnyObject] = [objectsToShare,someText]
let activityViewController = UIActivityViewController(activityItems : sharedObjects, applicationActivities: nil)
activityViewController.popoverPresentationController?.sourceView = self.view
activityViewController.excludedActivityTypes = [ UIActivityTypeAirDrop, UIActivityTypePostToFacebook,UIActivityTypePostToTwitter]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
I achieve this with the help of VisualActivityViewController which is present in this GitHub repository
It gives me a nice, custom view as well--one that shows the user both the text and image that the user is going to share.
func pickerView(sender : UIButton) {
let message="text"
let objectsToShare = [message]
let wsActivity = WhatsAppActivity()
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: [wsActivity])
activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList,UIActivityTypeCopyToPasteboard,UIActivityTypeSaveToCameraRoll,UIActivityTypePrint]
self.presentViewController(activityVC, animated: true, completion: nil)
}
How can i do the same thing with Facebook messenger ?
As far as my research went, you cannot share "string" in FB messenger. This has something to do with FB messenger policy (lost link ref for this). In order to share on Facebook messenger, your "activityItems: objectsToShare" should contain an NSURL. I have tried sharing multiple NSRULs and it did not work out.
You can pass an array of [String, NSURL] for example:
func pickerView(sender : UIButton) {
let message="text"
let url = NSURL(String: "https://www.google.com")!
let objectsToShare = [message, url] //this is now an [AnyObject]
//assuming you are don't have applications to exclude
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: [wsActivity])
self.presentViewController(activityVC, animated: true, completion: nil)
}
You will find both whatsapp and FB messenger showing up in your share sheet. However, FB messenger will only use the NSURL its, and ignore the String item in the AnyObject Array. WhatsApp will show the text followed by the link.
You might be able to do what you want to do using the FB SDK. I have not tried it personally though.
If you want to present facebook app in UIActivityViewController
than not specify any excludedActivityTypes property .
Because excludedActivityTypes: [String]? //default is nil.`
so just use as
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: [wsActivity])
self.presentViewController(activityVC, animated: true, completion: nil)
it will show you all option including facebook , twitter ext.
I'm developing part of an app so that when you tap the share button, it allows you to instantly share a screenshot of your highscore along with a message. I haven't been able to produce/share a screenshot, and when I tap the share button, the app only allows me to copy my default text or "Mail" my default text, not allowing me to post to Facebook, Twitter, Messages, and more.
func shareButtonPress() {
var postPhrase = "Just hit \(highscore)! Beat it! #SwypIt"
//Generate the screenshot
UIGraphicsBeginImageContext(view.frame.size)
view.layer.renderInContext(UIGraphicsGetCurrentContext())
var image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
var postImage = UIImage(named: "\(image)")
var activityViewController : UIActivityViewController = UIActivityViewController(activityItems: [postPhrase, postImage!], applicationActivities: nil)
self.presentViewController(activityViewController, animated: true, completion: nil)
}
What is the best way of going about this? Thanks!
This is how i handle sharing in my app.
func socialShare(#sharingText: String?, sharingImage: UIImage?, sharingURL: NSURL?) {
var sharingItems = [AnyObject]()
if let text = sharingText {
sharingItems.append(text)
}
if let image = sharingImage {
sharingItems.append(image)
}
if let url = sharingURL {
sharingItems.append(url)
}
let activityViewController = UIActivityViewController(activityItems: sharingItems, applicationActivities: nil)
activityViewController.excludedActivityTypes = [UIActivityTypeCopyToPasteboard,UIActivityTypeAirDrop,UIActivityTypeAddToReadingList,UIActivityTypeAssignToContact,UIActivityTypePostToTencentWeibo,UIActivityTypePostToVimeo,UIActivityTypePrint,UIActivityTypeSaveToCameraRoll,UIActivityTypePostToWeibo]
self.presentViewController(activityViewController, animated: true, completion: nil)
}
I have excluded a number of sharing options using .excludedActvityTypes.
Then whenever you hit the share button have it call this
socialShare(sharingText: "Just hit \(highscore)! Beat it! #SwypI", sharingImage: UIImage(named: "The screenshot you are saving"), sharingURL: NSURL(string: "http://itunes.apple.com/app/"))
The reason you are not seeing Twitter and Facebook as sharing options is because you need to be signed into them within the settings on the IPhone. Not the individual apps.
Hope this helps.
Use a SLComposeViewController.
import Social
func shareButtonPress() {
var postPhrase = "New high score \(highscore)!"
//Generate the screenshot
UIGraphicsBeginImageContext(view.frame.size)
view.layer.renderInContext(UIGraphicsGetCurrentContext())
var image = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()
var postImage = UIImage(named: "\(image)")
let shareToFacebook = SLComposeViewController(forServiceType: SLServiceTypeFacebook)
shareToFacebook.setInitialText(postPhrase)
shareToFacebook.addImage(postImage)
presentViewController(shareToFacebook, animated: true, completion: nil)
}
