我正在尝试升级到最新版本的 OpenTok iOS SDK。但是，我不断收到大量链接错误，如下所示。好像这个最新版本不支持armv7。

但是，lipo 命令确认该框架确实支持 armv7 和 arm64 架构:

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

我已无计可施，如有任何帮助，我们将不胜感激。

谢谢!

最佳答案

好的，由于 OpenTok 支持团队的及时响应，我解决了这个问题!我也在他们的支持论坛上发布了同样的问题。 ( https://forums.tokbox.com/post55977 )

这是对我有用的解决方案(从上面的链接逐字记录)

What are your Build settings? armv7 is supported.

also make sure that you have added the new lib/frameworks as follows:

- Add VideoToolbox.framework.
- Remove libstdc++ and add libc++
- add GLKit.framework (if not there previously)

我的框架列表中缺少上述几个文件。我附上了完整列表的屏幕截图，以防其他人遇到同样的问题。

我在这上面浪费了将近 6 个小时!! :(
