我试图升级到最新版本的OpenTok iOS SDK。然而，我一直收到像下面这样的大量链接错误。看起来这个最新版本不支持armv7。
Undefined symbols for architecture armv7:

然而，lipo命令确认该框架支持armv7和arm64两种架构：
$> lipo -info OpenTok.framework/OpenTok
Architectures in the fat file: OpenTok.framework/OpenTok are: armv7 armv7s i386 x86_64 arm64
我已经到了无计可施的地步，非常感谢任何帮助。
谢谢！
