iOS安装相同应用程序的联系人列表 [英] iOS List of Contacts With Same App Installed

问题描述

我正在寻找一种方法来为安装相同应用程序的用户创建iOS上的联系人列表。也许是一种同步Facebook联系人并发送电子邮件邀请到这些联系人安装该应用程序的方式。关键是我需要一些方法来知道我手机上的哪些联系人已经安装了应用程序，我似乎无法找到有关不同方法的信息。

I'm looking for a way to create a list of contacts on iOS for people who have the same app installed. Maybe a way to sync Facebook contacts and send e-mail invitations to those contacts to install the app. The point is that I need some way to know which contacts on my phone have the app installed and I can't seem to find information on the different approaches to this.

有没有API可以帮助我？有多种方法呢？哪里甚至开始这样做？创建我的联系人列表是很容易的。检测哪些安装有我的应用程序是一个不同的故事。

Are there any APIs to help me? Are there multiple approaches to this? Where do I even begin to do this? Creating a list of my contacts is easy enough. Detecting which ones have my app installed is a different story.

推荐答案

我唯一的想法是使用服务器。您将联系人（最好匿名）传输到服务器，您可以确定哪个联系人也安装了该应用程序。服务器返回结果。

The only idea I have, would be to use a server. You transfer your contacts (best anonymized) to the server and there you can determine which contact also has the app installed. The server returns the result.

基本上所有具有联系人列表的应用程序都知道使用这种方法（例如whatsapp）。

Basically all apps with a "contact list" I know of use this approach (e.g. whatsapp).

对于匿名化检查哈希函数。

For the anonymisation check hash-functions.
