ios5 ARC 什么是从 ARC 中排除文件的编译器标志?

问题描述

谁能帮我记住告诉 XCode 对某些文件不使用 ARC 的标志是什么?我的项目中有几个文件被标记为这样...直到我添加了另一个文件并决定将其转换为 ARC.听起来很容易，对吧?我希望我能够简单地检查我想要的文件并让 XCode 发挥它的魔力.好吧，不是那么容易，在预检查期间它从文件中删除了所有 -Noarc 标志，现在我需要手动将标志重新应用于多个文件.

Can anyone help me remember what was the flag to tell the XCode to not use ARC for some file? I had several files in my project marked as such... Until I added another file and decided to convert that one to ARC. Sounds easy, right? I expected that I would be able to simply check a file that I want and let the XCode do it's magic. Well, not so easy, during pre-check it stripped all -Noarc flags from the files and now I need to manually re- apply the flag to several files.

这个故事的寓意是:一旦您的项目在 ARC 中并且您有一些文件标记为无 ARC，请不要从 Refactor>Convert to ARC 重新运行转换为 ARC 工具.即使预检查失败，它也不会恢复您的设置.

the moral of this story is: once your project is in ARC and you have some files marked as no ARC, do not re-run the convert to ARC tool from Refactor>Convert to ARC. It will not restore your settings even if pre-check fails.
