提前致谢。

Answer 1

您需要将 MobileVLCKit 更新到版本“3.0.0a38”或更高版本的 pod 'MobileVLCKit-unstable'。此问题已解决。没有办法让旧版本的库以任何方式工作，因为它从后台线程调用 UIKit。

Answer 2

终于找到解决办法了...

现在 'MobileVLCKit-Unstable' 版本已于 9 月 20 日更新为主版本，使用来自后台线程的 UIKit（iOS 11 视频播放）问题。

解决方案1：

将 pod 'MobileVLCKit-unstable', '3.0.0a38' 添加到 podfile 和运行 pod install

解决方案 2：

从以下 URL 克隆了存储库：http://code.videolan.org/videolan/VLCKit.git
打开终端，导航到根目录并执行./buildMobileVLCKit.sh -f（注意：可能需要1-2小时才能完成）
成功完成后，MobileVLCKit.framework 将在 VLCKit/build/ 文件夹位置生成。
只需将其拖到您的项目中即可。
