如何在Swift中在Facebook上分享视频？

import FacebookCore

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    ApplicationDelegate.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
    return true
}

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    ApplicationDelegate.shared.application(app, open: url, options: options)
    return true
}

import FacebookShare

@IBAction func shareButtonTapped(_ sender: UIButton) {
    guard let videoURL = URL(string: "YOUR_VIDEO_URL") else { return }
    
    let content = VideoShareContent(video: Video(url: videoURL))
    let shareDialog = ShareDialog(content: content)
    shareDialog.mode = .automatic
    
    present(shareDialog, animated: true)
}
