Swift UIActivityViewController - ios

Question

Could anyone tell me how to implement "Open in Safari" in UIActivityViewController? I know this questions is a duplicate of another question posted a long time ago, and the method at that time was by using a framework that can no longer be used.
The data I am sharing is a URL. I already have a fully working ActivityVC and I only need to add that “open in safari” button.
Thank you very much.
code:
#IBAction func shareButtonPressed(_ sender: UIButton) {
let activityVC = UIActivityViewController(activityItems: [URL(string: urlStr)!], applicationActivities: nil)
activityVC.popoverPresentationController?.sourceView = self.view
self.present(activityVC, animated: true, completion: nil)
}

Answer 1

You need to implement your own activity, please check the code below.
import UIKit
final class SafariActivity: UIActivity {
var url: URL?
override var activityImage: UIImage? {
return UIImage(named: "SafariActivity")!
}
override var activityTitle: String? {
return NSLocalizedString("Open in Safari", comment:"")
}
override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
for item in activityItems {
if
let url = item as? URL,
UIApplication.shared.canOpenURL(url)
{
return true
}
}
return false
}
override func prepare(withActivityItems activityItems: [Any]) {
for item in activityItems {
if
let url = item as? URL,
UIApplication.shared.canOpenURL(url)
{
self.url = url
}
}
}
override func perform() {
var completed = false
if let url = self.url {
completed = UIApplication.shared.openURL(url)
}
activityDidFinish(completed)
}
}
let url = URL(string: "http://www.apple.com")!
let activityViewController = UIActivityViewController(activityItems: [url], applicationActivities: [SafariActivity()])
present(activityViewController, animated: true, completion: nil)

Updated to Swift 5.1 & iOS 13
Bonus:
ActivityType extension to use with .excludedActivityTypes.
UIImage(systemName:) to use SF Symbols plus .applyingSymbolConfiguration to take advantage of its flexibility.
To improve:
Implement completion handler on UIApplication.shared.open to handle errors (unlikely to occur).
import UIKit
extension UIActivity.ActivityType {
static let openInSafari = UIActivity.ActivityType(rawValue: "openInSafari")
}
final class SafariActivity: UIActivity {
var url: URL?
var activityCategory: UIActivity.Category = .action
override var activityType: UIActivity.ActivityType {
.openInSafari
}
override var activityTitle: String? {
"Open in Safari"
}
override var activityImage: UIImage? {
UIImage(systemName: "safari")?.applyingSymbolConfiguration(.init(scale: .large))
}
override func canPerform(withActivityItems activityItems: [Any]) -> Bool {
activityItems.contains { $0 is URL ? UIApplication.shared.canOpenURL($0 as! URL) : false }
}
override func prepare(withActivityItems activityItems: [Any]) {
url = activityItems.first { $0 is URL ? UIApplication.shared.canOpenURL($0 as! URL) : false } as? URL
}
override func perform() {
if let url = url {
UIApplication.shared.open(url)
}
self.activityDidFinish(true)
}
}

Try this Link if it meets your requirement

Code Required
class FavoriteActivity: UIActivity {
override func activityType() -> String? {
return "TestActionss.Favorite"
}
override func activityTitle() -> String? {
return "Add to Favorites"
}
override func canPerformWithActivityItems(activityItems: [AnyObject]) -> Bool {
NSLog("%#", __FUNCTION__)
return true
}
override func prepareWithActivityItems(activityItems: [AnyObject]) {
NSLog("%#", __FUNCTION__)
}
override func activityViewController() -> UIViewController? {
NSLog("%#", __FUNCTION__)
return nil
}
override func performActivity() {
// Todo: handle action:
NSLog("%#", __FUNCTION__)
self.activityDidFinish(true)
}
override func activityImage() -> UIImage? {
return UIImage(named: "favorites_action")
}
}
Usage
#IBAction func showAvc(sender: UIButton) {
let textToShare = "Look at this awesome website!"
let myWebsite = NSURL(string: "http://www.google.com/")!
let objectsToShare = [textToShare, myWebsite]
let applicationActivities = [FavoriteActivity()]
let avc = UIActivityViewController(activityItems: objectsToShare, applicationActivities: applicationActivities)
self.presentViewController(avc, animated: true, completion: nil)
}
