我对在我的应用中播放YouTube的视频有以下要求：
- 容器视图控制器出现时自动播放
- 检测视频何时完成(在此事件中启用控件(
- 它开始不是全屏
- 支持全屏端口和横向
- 与 IOS 7 和 8 完全兼容
首先，我尝试youtube-ios-player-helper，结果如下：
- IOS 8：完美工作
- IOS 7：视频每次全屏暂停，播放不流畅。
我认为这可能是更好的解决方案，但我无法使其在 IOS 7 中正常工作。
第二个也是实际选项，我使用混合解决方案：带有youtube-ios-player-helper的IOS 8和带有UIWebView和嵌入youtube播放器的IOS 7。结果：
- IOS 8：完美工作
- IOS 7：工作，但1/5视频自动播放不起作用，因此未检测到视频完成(我不知道为什么(
我感谢任何关于更好解决方案的建议，
我的实际代码(第二个选项(：

我在 iOS
