ios - 如何使用 Xcode 制作一个 imessage 扩展包以便可以导入

Question

我们使用Unity生成一个项目到Xcode，并希望利用iMessage扩展，但唯一的方法是在Unity生成Xcode项目后进行扩展，所以每次我们构建项目时我们应该重新设置 iMessage 扩展。

尽管我们已将 iMessage 扩展制作为一个文件夹并保存在磁盘上，因此每次生成 Xcode 项目时我们都必须

1. 使用 Xcode 添加 iMessage 扩展功能。
2. 将某些内容拖到 Xcode 中，以使用预制代码覆盖生成的代码。

这个过程很烦人，所以我们正在寻找其他一些容易做到这一点的方法。

有什么办法可以做到这一点吗？谢谢。

是的，您可以为此使用 Unity xcode api参见 https://bitbucket.org/Unity-Technologies/xcodeapi

基本上，您创建一个构建后处理器，它创建一个新目标并将标签资源添加到新生成的构建中。
