iOS 录屏功能开始录制失败

问题：在开发录屏功能时报如下错误：

2021-05-14 10:51:51.213305+0800 ScreenRecorderDemo[3316:1068581] -[UIWindow endDisablingInterfaceAutorotationAnimated:] called on <UIWindow: 0x101406310; frame = (0 0; 375 812); gestureRecognizers = <NSArray: 0x281d55da0>; layer = <UIWindowLayer: 0x2813365a0>> without matching -beginDisablingInterfaceAutorotation. Ignoring.

原因：使用Main.storyboard的方式作为程序的入口，并且在AppDelegate中添加了UIWindow

解决：去掉AppDelegate中添加的UIWindow，或者不使用Main.storyboard
