Xcode IOS 7和IOS 8中的Youtube API

我对在我的应用程序中播放youtube视频有以下要求：

• 当容器视图控制器出现时自动播放
• 检测视频何时完成（我在此事件中启用控件）
• 它不是全屏的
• 支持全屏portrail和横向
• 与IOS 7和IOS 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：视频在全屏上每次暂停，不流畅播放

我想这可能是更好的解决方案，但我不能让它在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： IOS 8带有youtube IOS player助手，IOS 7带有UIWebView和嵌入式youtube播放器。结果:

• IOS 8：完美工作
• IOS 7：可以工作，但1/5视频自动播放不工作，因此未检测到视频完成（我不知道为什么）

我很感激任何关于更好解决方案的建议

我的实际代码（第二个选项）：
