      关于升级iOS10和Xcdoe8的提示:    
  在Xcode8环境下将项目运行在iOS10的设备/模拟器中，访问相册和相机需要额外配置info.plist文件。分别是Privacy - Photo Library Usage Description和Privacy - Camera Usage Description字段，详见Demo中info.plist中的设置。

 A：是否有集成GKNavigationBarViewController？需要升级到2.0.4及以上版本，详见issue：[https://github.com/QuintGao/GKNavigationBarViewController/issues/7](https://github.com/QuintGao/GKNavigationBarViewController/issues/7)。       
 
+**Q：有的视频导出失败？**            
+A：升级到2.2.6及以上版本试试，发现是修正视频转向导致的，2.2.6开始默认不再主动修正。如需打开，可设置needFixComposition为YES，但有几率导致安卓拍的视频导出失败。       
+
+**Q：视频导出慢？**            
+A：视频导出分两步，第一步是通过PHAsset获取AVURLAsset，如是iCloud视频则涉及到网络请求，耗时容易不可控，第二步是通过AVURLAsset把视频保存到沙盒，耗时不算多。但第一步耗时不可控，你可以拷贝我源码出来拿到第一步的进度给用户一个进度提示...
