我正在尝试使用Google Cast Remote Display。只需添加GoogleCastRemoteDisplay.framework即可导致链接错误。我已经整理了一些，但无法弄明白......

有人有想法吗？

通过运行“pod install”解决它而不是手动引入.framework然而这是一个统一项目，所以有问题 select customer_id as customer.id ....目标覆盖`Pods / Target Support Files / Pods / Pods.release.xcconfig'中定义的Unity-iPhone [Release]构建设置。这可能会导致CocoaPods安装出现问题

转到项目构建设置 - ＆gt;其他链接器标志并添加了$（继承）

AudioToolbox
CoreMedia
corevideo的
OpenGLES
QuartzCore

和Metal如果使用那种渲染方法。
