OpenTok（iOS）v2.4.0（64位）-体系结构armv7的未定义符号

我正在尝试升级到最新版本的OpenTok iOS SDK。但是，我不断收到大量的链接错误，如下所示。似乎此最新版本不支持armv7。

但是，lipo命令确认该框架确实支持armv7和arm64体系结构：

$> lipo -info OpenTok.framework/OpenTok
Architectures in the fat file: OpenTok.framework/OpenTok are: armv7 armv7s i386 x86_64 arm64

我尽力了，任何帮助将不胜感激。

谢谢！
