ios - 如何通过使用 git 提交号作为 xcode 内部版本号来避免无限循环

Question

我最近使用脚本来增加与 git 提交相关的项目构建号，但我遇到了无限循环。

我构建，然后构建号被更改，然后我提交，因为 info.plist 被更改，然后构建号将在下次构建时更改，所以我必须再次提交，因为 info.plist 已更改，然后你就知道会发生什么了。

有什么办法可以避免这种情况吗？还是有更好的方法来自动增加内部版本号？

附言。因为我和其他人一起工作过这个项目，所以每次构建时手动更改数字或颠簸它很难保持数字。

是的，这是一个经典问题。我使用类似的技术，但我没有将内部版本号与 git 提交相关联，而是检测源树中文件的更改与版本文件(一个简单文件保存版本和内部版本号)。如果有变化，我会修改内部版本号。

这是我使用的 python 脚本。您应该在您的 Xcode 项目中将其作为一个单独的目标，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 的位置下方:

#!/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 ]
