FB App邀请Xamarin

Question

我正在研究如何实现Facebook邀请对话框,并注意到Facebook现在提供了一个新的FB App Invite产品.有没有办法在Xamarin iOS中使用新的App Invite产品？

谢谢!

Answer 1

这是app邀请的实现

您需要为appinvites创建Native实现

只需创建一个名为IFacebookService的接口

定义方法定义,如示例所示

public interface IFacebookservice{
  InviteFriends (string appLinkURL, string previewImageURL);
}

并在平台端执行该实现,如下所示

IOS FacebookService.CS

public void InviteFriends (string appLinkURL, string previewImageURL)
{
            var fromController = UIApplication.SharedApplication.KeyWindow.RootViewController;
            var content = new AppInviteContent {
                AppLinkURL = new NSUrl (appLinkURL),
                PreviewImageURL = new NSUrl (previewImageURL)
            };
            AppInviteDialog.Show (fromController, content, null);
}

Android的 FacebookService.Cs

  public void InviteFriends(string appLinkURL, string previewImageURL)
    {
        if (AppInviteDialog.CanShow())
        {
            var activity = Xamarin.Forms.Forms.Context as Activity;
           var content =new AppInviteContent.Builder().SetApplinkUrl(appLinkURL).SetPreviewImageUrl(previewImageURL).Build() as AppInviteContent;
            AppInviteDialog.Show(activity, content);
        }
    }

用于Xamarin表格

  var facebookservice=Dependency.Get<IFacebookservice>()
    button.click+=delegate{facebookservice.InviteFriends("appurl","previewimageurl")}
