完全删除 Three20 Facebook API 的说明
之前我将 Three20 及其安装脚本添加到我的 iPhone 项目中。我不想再使用它并想将其删除。我看到了有关此问题的各种问题，但没有找到彻底删除它的干净方法。
Previously I added three20 with the install script to my iPhone project. I no longer want to use it and would like to remove it. I saw various questions about this, but didn't see a clean cut way to thoroughly remove it.

我仅通过从大型项目中删除 Three20 库就成功删除了 Three20。完成后，您需要修复链接错误，用您自己的代码替换 Three20 以前提供的例程。
您可能会发现最好创建一个新项目并将要保留的代码移入其中。您不仅可以从彻底重新检查代码中受益，并且可能会发现一些需要改进或丢弃的内容，您还可以真正摆脱所有 Three20 工件和设置，并且您可能会避免我遇到的一些错误 - 例如 Three20 的 URL基于导航系统转义所有可能或可能不匹配您自己的首选资源命名方案的 URL。
如果它是代码，您只想让它工作并且不管它，也许脚本可以工作。如果您想要维护和使用它的代码，那么在其中投入时间可能是值得的。
I had success removing Three20 by just removing the Three20 libraries from a large project. Once that is done you need to fix up the link errors, substituting your own code for the routines formerly provided by Three20.
You might find it better to create a new project and move the code you want to keep into it. Not only will you benefit from a thorough reexamination of code and probably find a fair bit to improve or discard, you will truly get rid of all three20 artefacts and settings, and you might avoid some bugs that I encountered - like the fact that three20's URL-based navigation system escapes all URLs which may or may not match your own preferred resource naming scheme.
If it's code you just want to make work and leave alone maybe a script would work. If it is code you want to maintain and use it might pay to invest the time in it.
