ios5 ARC什么是编译标志从ARC中排除文件？ [英] ios5 ARC what is the compiler flag to exclude a file from ARC?

问题描述

-fno-objc-arc

任何人都可以帮助我记住什么是标志告诉XCode不使用ARC的某些文件？我有我的项目中有几个文件标记为这样...直到我添加了另一个文件，并决定将这一个转换为ARC。听起来很容易，对吧？我希望我能够简单地检查一个我想要的文件，让XCode做它的魔法。好吧，不那么容易，在预检查它剥离所有-Noarc标志从文件，现在我需要手动重新应用标志到几个文件。

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.

这个故事的道德是：一旦你的项目是在ARC，你有一些文件标记为没有ARC，不要重新运行转换为ARC工具从重构>转换为ARC。即使预检查失败，也无法恢复您的设置。

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.
