ARC error when compiling
提问by Ben
I'm trying to compile using the LLVM GCC 4.0 compiler, and I get this error in multiple of my .m files: ARC forbids explicit message send of 'release' I've tried using -fno-objc-arc as a compiler flag but that returns the error: Unrecognized command line option "-fno-objc-arc".
我正在尝试使用 LLVM GCC 4.0 编译器进行编译，并且在我的多个 .m 文件中出现此错误：ARC 禁止“发布”的显式消息发送我已尝试使用 -fno-objc-arc 作为编译器标志但这会返回错误：无法识别的命令行选项“-fno-objc-arc”。
How can I solve this?
我该如何解决这个问题？

Simply remove all calls to -release. You're not allowed to call -releaseunder ARC because the compiler will insert all the necessary retain/releasecalls for you. Read more about ARC here.
只需删除对 的所有调用-release。你不能-release在 ARC 下调用，因为编译器会为你插入所有必要的retain/release调用。在此处阅读有关 ARC 的更多信息。
The other way is to use the conversion tool, and Xcode can convert your project to ARC (including removing these calls) for you:
另一种方法是使用转换工具，Xcode 可以为您将您的项目转换为 ARC（包括删除这些调用）：
To disable ARC entirely, change your build settings:
要完全禁用 ARC，请更改构建设置：
However I'd recommend you start using ARC, it will make things a lot easier and actually faster too.
但是我建议你开始使用 ARC，它会让事情变得更容易，实际上也更快。

If you happen to be using the ASI (http://allseeing-i.com/ASIHTTPRequest/How-to-use) api, refer to this answer as it needs to be built using -fno-obj-arc flags for specific classes... Files doesn't support the ARC feature, how to deal withand refer to the answer titled 'Disable ARC for that one class'
如果您碰巧使用 ASI ( http://allseeing-i.com/ASIHTTPRequest/How-to-use) api，请参阅此答案，因为它需要使用特定类的 -fno-obj-arc 标志构建...文件不支持 ARC 功能，如何处理和参考标题为“为该一类禁用 ARC”的答案
