如果我制作两个iPhone应用程序，我应该如何/应该共享自定义数据（不是联系人和类似的东西）？

If I make two iPhone applications, how can/should I share custom data (not contacts and stuff like that) among them?

推荐答案

有两种不同的方式。

您需要共享的数据是非持久性的。换句话说，你需要启动一个应用程序与一块数据，它可以做一些事情。在这种情况下，您将为每个应用程序注册一个特殊的URL方案。

1) The data you need to share is non-persistent. In other words you need to launch one application with a piece of data that it can do something with. In this case you would register a special URL scheme per application.

您可以通过Craig Hockenberry在他的 博文。

2）数据你需要共享是持久的。换句话说，你需要一个数据文件，这两个应用程序都可以读写。据我所知，除了将数据存储在远程服务器上之外，没有一种安全的方法可以做到这一点。如果您需要无需数据连接即可访问数据，则需要找出在各个应用和远程服务器之间同步数据的方法。

2) The data you need to share is persistent. In other words you need something like a data file that both applications can read and write too. As far as I know there isn't a safe way to do this other than storing your data on a remote server. If you need the data accessible without a data connection then you would need to figure out a way to sync data between the individual apps and the remote server.
