当我将iPhone项目转换Objective - c ARC为时，我总是遇到同样的错误：

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo: can't figure out the architecture type of: /Users/user/Library/Developer/Xcode/DerivedData/TestApp-fktzngidcyimjibgdosyphgbuzpe/Build/Intermediates/TestApp.build/Debug-iphoneos/TestApp.build/Objects-normal/armv7/TestAppCommand /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/lipo failed with exit code 1

请有人可以建议我如何解决这个问题？

If you are using 3rd party libraries that don't support ARC you should just add this flag to the files in question in your build phases/compile sources (prevents ARC on only those files). This should help you determine if your code is the issue or the library you are using (if that's the case).

-fno-objc-arc

尝试使用这个

我通过将 Project > Build Settings Architectures 中的 Valid Architecture 的值从默认的“armv6 armv7”更改为“armv7”来解决了这个问题。希望这可以帮助。

确保将 -fno-objc-arc 标志添加到每个实现文件（.m 文件）。

然后清理项目（项目菜单 -> 清理）并再次构建。在课堂上这样做时，我有时不得不清洁和建造两次。好像是个小bug。
