UIActivityViewController class is define under UIKit framework and inherits from UIViewController. This class makes sharing feature super easy. Using UIActivityViewController class we can post content to social media, copy content to pasteboard, send content via SMS and email, and more.

Share text message

Sharing text is one of the basic feature of UIActivityViewController

let shareContent = ["Write your share content"]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

Share image

You can easily share the image using below code

// Get the image which you want to share
guard let image = UIImage(named: "myImage.png") else { return }
let shareContent = [image]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

Share URLs

Share your urls

guard let url = URL(string: "http://swiftdevcenter.com/") else { return }
let shareContent = [url]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

Share text and URLs

We can share both text and URLs

let shareText = "This is text message to share"
guard let url = URL(string: "http://swiftdevcenter.com/") else { return }
let shareContent: [Any] = [shareText, url]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

Share text, image and URLs

We cans share text, image and URLs all three together

let shareText = "This is text message to share"
guard let url = URL(string: "http://swiftdevcenter.com/"),
    let image = UIImage(named: "myImage.png")
    else { return }
let shareContent: [Any] = [shareText, url, image]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

Share content with CompletionWithItemsHandler

CompletionWithItemsHandler is a closure which execute when UIActivityViewController dismissed. Inside this closure we can check the activity type, our sharing is success or not, returned items and error.

let shareContent = ["Write your share content"]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
self.present(activityController, animated: true, completion: nil)

//Completion handler
activityController.completionWithItemsHandler = { (activityType: UIActivity.ActivityType?, completed:
Bool, arrayReturnedItems: [Any]?, error: Error?) in
    if completed {
        print("share completed")
        return
    } else {
        print("cancel")
    }
    if let shareError = error {
        print("error while sharing: \(shareError.localizedDescription)")
    }
}

Remove activity type with excludedActivityTypes

We can remove any activity type using excludedActivityTypes. Let’s say you want to remove the Facebook and Twitter sharing then simply exclude these activity.

let shareContent = ["Write your share content"]
let activityController = UIActivityViewController(activityItems: shareContent,
                                                  applicationActivities: nil)
activityController.excludedActivityTypes = [.postToFacebook, .postToTwitter]
self.present(activityController, animated: true, completion: nil)
