将单个文件转换为arc？(Converting individual files to arc?)

将单个文件转换为arc？(Converting individual files to arc?)

我已经看到很多关于将整个项目转换为弧然后使用标志告诉Xcode哪些不能转换的信息。

将单个文件转换为arc的方法如何？ 我试过了，运行良好。 我可以这样做吗？ 我有点担心，因为如果我在这里和那里转换东西，整个项目不会转换为弧，它们会导致内存泄漏。

I've seen lots of info about converting a whole project to arc and then using flags to tell Xcode which ones not to convert.

What about converting only individual files to arc? I tried it, and it runs fine. Can I do that? I'm kind of worried that since the whole project isn't converted to arc if I convert things here and there they'll cause memory leaks.

是的你可以。 但是，您需要告诉编译器哪些文件不是ARC。 这可以在您的项目设置中执行。 转到your project > Select the target of the app in question > Build Phases 。 现在拖放“Compile Sources”并选择你不想用ARC编译的文件，按下ENTER键，会出现一个小小的弹出框。 在这里你可以写-fno-objc-arc 。 按Done ，你就完成了。

在编译时，它会尝试将自动引用计数添加到没有-fno-objc-arc标志的文件。 使用非弧库时非常有用，如ASIHTTPRequest或MBProgressHud（及其他）。

Yes, you can. However, you need to tell the compiler which files are not ARC. This you can do in your project settings. Go to your project > Select the target of the app in question > Build Phases. Now drop down the "Compile Sources" and select the files you wish not to compile with ARC, press ENTER and a little popup box will appear. Here you can write -fno-objc-arc. Press Done and you are done.

When compiling, it will try to add automated reference counting to the files which do not have the -fno-objc-arc flag. Very usefull when using non-arc libs such as ASIHTTPRequest or MBProgressHud (and others).
