是的，这是一个经典问题。我使用了类似的技术，但我没有将内部版本号与 git 提交相关联，而是检测与 version 文件（一个简单文件）的修改时间相关的源树中文件的更改保存版本和内部版本号）。如果有变化，我会修改内部版本号。
这里是我使用的 python 脚本。您应该在您的 Xcode 项目中使其成为一个单独的目标，然后使其他目标依赖于该目标。它将根据需要使用新版本/内部版本号更新您的 .plist 文件。它假定源代码树位于版本文件的位置之下：
#!/usr/bin/env python
#
# Bump build number in Info.plist files if a source file have changed.
#
# usage: bump_buildnum.py buildnum.ver Info.plist [ ... Info.plist ]
