Question

我尝试使用本指南尝试使用Facebook App Invites： Facebook App Invites iOS我的代码如下：

@IBAction func tapInviteFriends() {
    if AccessToken.current?.authenticationToken == nil {
        AccessToken.current = AccessToken.init(authenticationToken: stringValue(object: UserDefaults.standard.string(forKey: “facebookToken”)))
    }

    let inviteDialog:FBSDKAppInviteDialog = FBSDKAppInviteDialog()

    if(inviteDialog.canShow()){
        let appLinkUrl:URL = URL(string: "https://fb<dot>me/1358637537516578")!
        let previewImageUrl:URL = URL(string: "http://is4.mzstatic.com/image/thumb/Purple122/v4/e6/a2/1a/e6a21ada-b51a-17fe-4522-6618f864cc80/source/175x175bb.jpg")!

        let inviteContent:FBSDKAppInviteContent = FBSDKAppInviteContent()
        inviteContent.appLinkURL = appLinkUrl
        inviteContent.appInvitePreviewImageURL = previewImageUrl
        inviteContent.destination = .facebook

        inviteDialog.content = inviteContent
        inviteDialog.delegate = self
        inviteDialog.fromViewController = self

        inviteDialog.show()
    }

}

func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didCompleteWithResults results: [AnyHashable : Any]!) {
    if results != nil{
        let resultObject = NSDictionary(dictionary: results)
        if let didCancel = resultObject.value(forKey: “completionGesture”)
        {
            if (didCancel as AnyObject).caseInsensitiveCompare(“Cancel”) == ComparisonResult.orderedSame
            {
                print(“User Canceled invitation dialog”)
            }
        }
    }
}

func appInviteDialog(_ appInviteDialog: FBSDKAppInviteDialog!, didFailWithError error: Error!) {
    print(“Error tool place in appInviteDialog \(error)“)
}

然而，这仅显示了当其通过Wi-Fi并且当其在3G / LTE上无法工作时分享的朋友列表，并且对话窗口刚刚关闭并转到错误方法。有没有办法使它不仅在Wi-Fi上工作？或者这是Facebook的错误吗？

我不认为它与wifi有什么关系。你应该买一部更好的手机。

iOS Facebook App Invites仅适用于WiFi
