全屏iOS分享扩展

Question

I know how to create an iOS share extension, but what I can't figure out is if there is a way to make it fullscreen such as an Action extension?

Pinterest seem to do this but I'm not sure how.

The docs for an Action extension say to use:

          <key>NSExtensionActionWantsFullScreenPresentation</key>
    <true/>

In the plist file for the extension but this doesn't seem to have an effect in the Share extension?

Is there anyway to accomplish this?

You can get ideas from there iOS Full Screen Share Extension and you can find the updated syntax for the code snippets below which is compatible with Swift 3 and Swift 4

EntryViewController

import UIKit

@objc(EntryViewController)

class EntryViewController : UINavigationController {

    override init(rootViewController: UIViewController) {
        super.init(rootViewController: ShareViewController())
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)!
    }

    override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
        super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
    }

    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        self.view.transform = CGAffineTransform(translationX: 0, y: self.view.frame.size.height)
        UIView.animate(withDuration: 0.3, animations: { () -> Void in
            self.view.transform = .identity
        })
    }

}

ShareViewController

import UIKit
import Social

class ShareViewController: SLComposeServiceViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        self.view.backgroundColor = UIColor.white
        self.navigationItem.title = "Share"

        self.navigationItem.leftBarButtonItem = UIBarButtonItem(barButtonSystemItem: .cancel, target: self, action: Selector(("cancelButtonTapped:")))
        self.navigationItem.rightBarButtonItem = UIBarButtonItem(barButtonSystemItem: .save, target: self, action: Selector(("saveButtonTapped:")))
    }

    func saveButtonTapped(sender: UIBarButtonItem) {
        self.hideExtensionWithCompletionHandler(completion: { (Bool) -> Void in
        self.extensionContext!.completeRequest(returningItems: nil, completionHandler: nil)
        })
    }

    func cancelButtonTapped(sender: UIBarButtonItem) {
        self.hideExtensionWithCompletionHandler(completion: { (Bool) -> Void in
        self.extensionContext!.cancelRequest(withError: NSError())
        })
    }

    func hideExtensionWithCompletionHandler(completion: @escaping (Bool) -> Void) {
        UIView.animate(withDuration: 0.3, animations: { 
        self.navigationController!.view.transform = CGAffineTransform(translationX: 0, y: self.navigationController!.view.frame.size.height)
        }, completion: completion)
    }

}

I have solved full screen share extension.

It's simple.

You add NSExtensionActionWantsFullScreenPresentation and set TRUE under NSExtension of extension app's info.plist
