從facebook-ios-sdk切換到facebook-swift-sdk，在新代碼中使用FBSDKAppInviteDialogDelegate

Question

我正在從Facebook iOS SDK切換到Facebook Swift SDK。

我希望收到應用邀請結果的通知。這是我在舊代碼：

extension VolumesListViewController: FBSDKAppInviteDialogDelegate { 

    public func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: Error!) { 
     ... 
    } 


    func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [AnyHashable: Any]!) { 
     ... 
    } 
} 

看來，在斯威夫特SDK，這DialogDelegate封裝成的框架和實施沒有打開：

所以，這是SDKDelegate：

extension AppInvite { 
    internal class SDKDelegate: NSObject, FBSDKAppInviteDialogDelegate { 
     internal var completion: ((Result) -> Void)? 

     func setupAsDelegateFor(_ dialog: FBSDKAppInviteDialog) { 
      // We need for the connection to retain us, 
      // so we can stick around and keep calling into handlers, 
      // as long as the connection is alive/sending messages. 
      objc_setAssociatedObject(dialog,  Unmanaged.passUnretained(self).toOpaque(), self, .OBJC_ASSOCIATION_RETAIN) 
      dialog.delegate = self 
     } 

     func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog?, didCompleteWithResults results: [AnyHashable: Any]?) { 
      completion?(.success(results?.keyValueFlatMap { ($0 as? String, $1 as? String) } ?? [:])) 
     } 

     func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog?, didFailWithError error: Error) { 
      completion?(.failed(error)) 
     } 
    } 
} 

如何在不使用舊框架的情況下實現與通知相同的功能？

我的理由是這樣的：

爲Facebook SDK斯威夫特的框架以同樣的方式作爲Facebook的SDK適用於iOS的組織方式。他們也依賴Facebook的iOS SDK，儘管這可能會在未來某個時候發生變化。

所以，對什麼事都變得清楚，我只是張貼在SO一個問題：

這是我發現：我可以使用封閉落後的AppInvite.Dialog.show（來自：邀請:)有反饋從對話框：

let appInvite = AppInvite(appLink: URL(string: "http://eggheadgames.com/cryptograms")!) 
do { 
    try AppInvite.Dialog.show(from: self, invite: appInvite) { result in 
     switch result { 
     case .success(_): 
      Logger.logUIEvent("InviteFriend", label: "called") 
     case .failed(_): 
      Logger.logUIEvent("InviteFriend", label: "unavailable") 
     } 
    } 
} catch _ { 
    Logger.logUIEvent("InviteFriend", label: "unavailable") 
}
