由于不能上传视频，姑且截几张图展示下样式

这里的H5动画是放入本地的H5文件，动画就不赘述了，
原生这边用的是WebView 加载动画，并实现交互
1，webView 的初始化：

圈起来的地方是和前端约定好的交互方法：

2，webView加载H5信息
NSString *path = [[NSBundle mainBundle] pathForResource:@"h5/index" ofType:@"html"];
NSString * urlstr= [NSString stringWithFormat:@"%@#/pages/goods/ask-answer/go-answer/index?order_sn=%@&token=%@",path,self.order_sn,[User getUserToken]];
NSString * pathStr = [@"file://" stringByAppendingString:urlstr];
NSURL *url = [NSURL URLWithString:pathStr];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];
如果有音乐的话，需要用AVPlayer播放相应的音乐

pragma mark - 播放音乐

-(void)playVideo {
NSURL * url = [NSURL URLWithString:kVodCodeURL];
AVPlayerItem * songItem = [[AVPlayerItem alloc]initWithURL:url];
AVPlayer * player = [[AVPlayer alloc]initWithPlayerItem:songItem];
self.player = player;
[player play];
}
3,在代理方法中处理交互事件
