Apple Mach-O链接器错误(20) - 架构armv7的未定义符号

Question

在我添加"libPusher-combined.a"及其头文件后,在"Other Linker Flags"构建设置中添加"-all_load"后,我收到了这些错误.我按照说明完全按照"-all_load"键入的部分(在"添加到iOS项目"中的"使用预编译的静态库"下,但最终得到20个Mach-O Linker错误.) /有人可以帮我这个吗？

以下是错误:

如果您需要更多信息,请询问.我希望我不会给太多麻烦.提前致谢.

Answer 1

检查以确保包含以下框架(通过https://github.com/square/SocketRocket):

框架依赖性

您的.app必须与以下框架/ dylib链接

libicucore.dylib CFNetwork.framework Security.framework Foundation.framework

Answer 2

确保在构建设置选项卡中的"其他链接器标志"中也有-licucore,如附带的屏幕截图所示:

Answer 3

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相关联.这删除了我的所有错误和警告.

Answer 4

对于最新的sdk,您应该添加:

libicucore.tbd 

因为libicucore.dylib不再存在.

希望.tbd扩展名不是"要删除"吗？

你可以在你的目标->构建阶段中检查一下吗？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建，无论我猜您正在使用 SRWebSocket 库。只需打开该项目并为模拟器进行构建，然后从构建文件夹复制文件，然后添加到您的项目中，如果您在设备上运行应用程序，则对设备执行相同的操作。
