ios - 全屏 iOS 分享扩展

Question

我知道如何创建 iOS 共享扩展，但我不知道是否有办法让它全屏显示，例如 Action 扩展？

Pinterest 似乎是这样做的，但我不确定是怎么做到的。

Action 扩展的文档说要使用:

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

在扩展的 plist 文件中，但这似乎对共享扩展没有影响？

有没有办法做到这一点？

你可以从那里得到想法iOS Full Screen Share Extension您可以在下面找到与 Swift 3 和 Swift 4

兼容的代码片段的更新语法

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)
    }
