clang error unknown unknown＆＃39; -fno-obj-arc＆＃39; AFNetworking Xcode 5.1

Question

所以我尝试在iPhone 7上运行我的应用程序，ASIHttp无效。经过一番搜索，我看到人们正在迁移到AFNetworking，所以我决定这样做。这是我做的：

• 将Xcode更新为版本5.1
• 按照说明here （设置cocoapods，安装afnetworking，更改项目）

并试图跑。第一次构建失败，显示以下消息：

clang: error: unknown argument: '-fno-obj-arc' [-Wunused-command-line-argument-hard-error-in-future]
clang: note: this will be a hard error (cannot be downgraded to a warning) in the future
Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang failed with exit code 1

我发现的这两个报告只有2个，这里和

他们告诉我在进行pod下载时添加一些标记：

ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future

那样做又试了一次，但没有用。现在我甚至不能回到另一个项目。到目前为止有没有人处理过这个问题？该选项在命令行中，但我找不到任何删除它。反正我不认为我应该这样做。

这是命令行，您可以在AFNetworking之后立即看到参数：

Answer 1

检查构建阶段部分以获取编译源，您应该拥有无弧标志（ -fno-objc- arc ），只需确保拼写正确。
