在此先感谢。

Answer 1

最后得到了解决......

现在“MobileVLCKit不稳定”的版本更新到主于09月20日从后台线程的UIKit（iOS版11视频播放）的问题。

解决方法1：

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

解决方案2：

1. 克隆从以下URL回购：http://code.videolan.org/videolan/VLCKit.git

2. 打开终端，导航到根目录并执行./buildMobileVLCKit.sh -f（注意：可能需要1-2小时才能将c完成）

3. 成功完成后，将在VLCKit/build /文件夹位置生成MobileVLCKit.framework。
4. 只需将其拖动到您的项目。

Answer 2

您需要将MobileVLCKit更新到版本为“3.0.0a38”或更高版本的Pod'MobileVLCKit-unstable'。此问题已解决。无法以任何方式使旧版本的库发挥作用，因为它从后台线程调用UIKit。
