你能解决这个问题吗？
@AshishKakkad 到目前为止，在这个问题上没有任何线索。仍在寻找解决方案。

【解决方案1】：

这是 ios13.0 中的一个错误。在展示VC时，ReplayKit使用UIApplicationRotationFollowingController(modalTransitionStyle = pageSheet)来展示一个RPBroadcastPickerStandaloneViewController(modalTransitionStyle = curl)。但是 curl 仅在之前的 vc 为 fullScreen 时可用。所以解决办法就是把presentApi挂钩，改变样式。
