How to change UIActivity Copy to copy Link in UIActivityViewController in Swift

Question

How can I change the text to copy link when the item being shared is a link

I am tried this but it does not work as expected

 @objc(CustomUIActivity) class CustomUIActivity: UIActivity { private var url = NSURL() override class var activityCategory: UIActivity.Category { return .share } override var activityType: UIActivity.ActivityType? { return .customuiactivity } override var activityTitle: String? { return "Copy Link" } override var activityImage: UIImage? { return UIImage(named: "icon-copy") } override func canPerform(withActivityItems activityItems: [Any]) -> Bool { for activityItem in activityItems { if let _ = activityItem as? NSURL { return true } } return false } var textToShare: String? override func prepare(withActivityItems activityItems: [Any]) { for activityItem in activityItems { if let url = activityItem as? NSURL { self.url = url } } } override func perform() { // perform your custom activity UIPasteboard.general.string = url.absoluteString activityDidFinish(true) } } extension UIActivity.ActivityType { static let customuiactivity = UIActivity.ActivityType("com.productHunt.copyLink") }

The "Copy" is the default system provided item that you cannot updated as UIActivity.activityTitle is read only.

However, you can add the custom activity item, you have almost did the same below is my version

class CustomUIActivity : UIActivity { var _activityTitle: String var _activityImage: UIImage? var activityItems = [Any]() var action: ([Any]) -> Void private var url = URL(string: "Nil") init(title: String, image: UIImage?, performAction: @escaping ([Any]) -> Void) { _activityTitle = title _activityImage = image action = performAction super.init() } override var activityTitle: String? { return _activityTitle } override var activityImage: UIImage? { return _activityImage } override var activityType: UIActivity.ActivityType? { return UIActivity.ActivityType(rawValue: "com.productHunt.copyLink") } override class var activityCategory: UIActivity.Category { return .action } override func canPerform(withActivityItems activityItems: [Any]) -> Bool { for activityItem in activityItems { if let _ = activityItem as? URL { return true } } return false } override func prepare(withActivityItems activityItems: [Any]) { for activityItem in activityItems { if let url = activityItem as? URL { self.url = url } } self.activityItems = activityItems } override func perform() { print("URL : \(String(describing: url?.absoluteString))") UIPasteboard.general.string = url?.absoluteString action(activityItems) activityDidFinish(true) } }

You can call initialize this CustomUIActivity as below:

 let customItem = CustomUIActivity(title: "Copy Link", image: UIImage(named: "icon-copy")) { sharedItems in for string in sharedItems { print("Here's the string: \(string) ") } } let items: [Any] = ["This app is my favorite", URL(string: "https://www.google.com")!] let ac = UIActivityViewController(activityItems: items, applicationActivities: [customItem]) present(ac, animated: true)

This will work, and copies the link:

Another solution is to define a custom UIActivityItemSource, like this:

class MyCustomItemSource: NSObject, UIActivityItemSource { private let propertyA: URL private let propertyB: String init(a: URL, b: String) { self.propertyA = a self.propertyB = b } func activityViewController(_ activityViewController: UIActivityViewController, itemForActivityType activityType: UIActivity.ActivityType?) -> Any? { switch activityType { case .copyToPasteboard: return a default: return "\(a.absoluteString)\nb" } } func activityViewControllerPlaceholderItem(_ activityViewController: UIActivityViewController) -> Any { return a } }

Then, use it as below:

let myItemSource = MyCustomItemSource(a: URL(string: "your url"), b: "Your text to share") let activityVC = UIActivityViewController(activityItems: [myItemSource], applicationActivities: []) vc.present(activityVC, animated: true)
