编译时出现ARC错误 [英] ARC error when compiling

问题描述

我正在尝试使用LLVM GCC 4.0编译器进行编译，并且我在我的.m文件中出现了这个错误：ARC禁止显式消息发送'release'
我尝试过使用-fno- objc-arc作为编译器标志但返回错误：无法识别的命令行选项-fno-objc-arc。

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".

我该如何解决这个问题？

How can I solve this?

推荐答案

只需删除对 -release 的所有调用。您不能在ARC下调用 -release ，因为编译器将插入所有必需的 retain / 发布为您打电话。详细了解ARC 此处。

Simply remove all calls to -release. You're not allowed to call -release under ARC because the compiler will insert all the necessary retain/release calls for you. Read more about ARC here.

另一种方法是使用转换工具，Xcode可以为您将项目转换为ARC（包括删除这些调用）：

The other way is to use the conversion tool, and Xcode can convert your project to ARC (including removing these calls) for you:

要完全禁用ARC，请更改构建设置：

To disable ARC entirely, change your build settings:

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。

However I'd recommend you start using ARC, it will make things a lot easier and actually faster too.
