苹果Mach-O链接器错误（20） – 架构armv7的未定义符号
我在添加“libPusher-combined.a”及其头文件后，在“Other Linker Flags”构build设置中添加“-all_load”后，收到了这些错误。 我完全按照“-all_load”（在“添加到您的iOS项目中”中的“使用预编译的静态库”部分）中的指示进行操作 ，但是最终我得到了20个Mach-O Linker错误。 /谁能帮我一下吗？
这里是错误：

你能检查你的目标 – >build设阶段。 这些文件是否存在？ 如果您正在运行模拟器，那么首先您需要为该库的模拟器进行构build，不pipe我是否使用SRWebSocket库。 只需打开该项目，只需构build模拟器，然后从构build文件夹复制文件，然后添加到您的项目，如果您正在设备上运行您的应用程序执行相同的设备。
检查以确保您包含以下框架（通过https://github.com/square/SocketRocket ）：
框架依赖关系
您的.app必须链接到以下框架/ dylibs
libicucore.dylib CFNetwork.framework Security.framework Foundation.framework
确保您在“其他链接器标志”中的“生成设置”选项卡中也有“-licucore”，如附件屏幕截图所示：
我将完整的SocketRocket文件夹复制到我的应用程序中，以便在我的应用程序中使用Web套接字，并将libicucore.dylib，CFNetwork.framework，Security.framework，Foundation.framework二进制文件与我的项目链接起来。 这删除了我所有的错误和警告。
对于最新的sdk，你应该添加：
libicucore.tbd
因为libicucore.dylib不存在了。
希望.tbd扩展名不是用来“删除”的？
在我的情况下，当我添加SystemConfiguration.framework到项目和问题去… 🙂
