ios - 引入 SocketRocket 时出现 Apple Mach-O 链接器错误

Question

我使用的是 Xcode 版本 6.0.1 (6A317)，并且很长一段时间都遇到 Apple Mach-O 错误。引入 SocketRocket 项目后出现此错误。

我已确保按照 https://github.com/square/SocketRocket 中给出的步骤进行操作

我看到的唯一异常(exception)是 SocketRocket.framework 在我尝试将其添加到 + Link Binary with libraries 下时显示为红色。

我添加了以下库:

Security.Framework
CFNetwork.Framework
UIKit.Framework
Foundation.Framework
libicucore.dylib
libsocketrocket.a
libresolv.dylib

我已将其他链接器标志设置为 -ObjC仅构建事件架构 - 否，因为将其设置为是会引发错误:检查依赖项。没有要编译的架构(ONLY_ACTIVE_ARCH=YES，active arch=x86_64，VALID_ARCHS=i386)。有效架构 - armv64 armv7 armv7s

这个问题真的很浪费我的时间。我尝试关注其他帖子，但没有任何办法可以帮助我解决问题!

Answer 1

1.- 您是否将一个 .m 文件导入到另一个 .m 文件而不是 Header 中？它有时会错误地发生并导致该问题。

2.- 在构建阶段下检查您的编译源，您没有包含相同的文件 2 次，尽管从外观上看这似乎不是问题。

3.- 如果一切都失败了。在管理器中为项目清理 DerivedData 文件夹。清理并重建。
