Quick start

1. Audio Recording(音频录制)

Just add the button that inherits from AudioRecordButton to the page and set the proxy. Call the proxy method endRecord to refresh the data when you end the audio recording to see the latest recording file.(只需要把继承于AudioRecordButton的按钮添加到页面上并设置代理即可，在结束音频录制时调用代理方法endRecord刷新数据就可以看到最新的录音文件)

   _recordButton.delegate = self;

   #pragma mark - audio delegate
    -(void)endRecord{
        [self refreshDataSource];
    }

2. Audio Play (音频播放)

AudioPlayView *voiceButton;
if (indexPath.row >= self.playViews.count || self.playViews.count == 0) {
voiceButton = [[AudioPlayView alloc] initWithFrame:CGRectMake(10, 10, 200, 30)];
voiceButton.filePath = filePath;
voiceButton.isShowLeftImg = YES;
if (![self.playViews containsObject:voiceButton]) {
[self.playViews addObject:voiceButton];
}
if (indexPath.row % 2 == 0){
voiceButton.isInvert = YES;
voiceButton.frame =CGRectMake(kScreenWidth-210, 10, 200, 30);
}
}else{
voiceButton = [self.playViews objectAtIndex:indexPath.row];
}
[cell.contentView addSubview:voiceButton];

Audio Play Delegate:

  [Audio shareAudio].audioPlay.delegate = self;

Audio Play Delegate Function:

    /// 开始播放音频（状态：加载中、加载失败、加载成功正在播放、未知）
    - (void)audioPlayBegined:(AVPlayerItemStatus)state;
    /// 正在播放音频（总时长，当前时长）
    - (void)audioPlaying:(NSTimeInterval)totalTime time:(NSTimeInterval)currentTime;
    /// 结束播放音频
    - (void)audioPlayFinished;

3. Video Recording (视频录制)

    _videoView  =[[VideoView alloc] initWithFMVideoViewType:TypeFullScreen];
    _videoView.delegate = self;
    [self.view addSubview:_videoView];

Video View Delegate:

    ///退出录制
    -(void)dismissVC;
    ///视频录制完成
    -(void)recordFinishWithvideoUrl:(NSURL *)videoUrl;

4. Video Play (视频播放)

    VideoPlayViewController *playVC = [[VideoPlayViewController alloc] init];
    playVC.videoUrl =  videoUrl;
    [self presentViewController:playVC animated:YES completion:nil];

5. AR Video Recording (AR动画录制)

    [Video shareVideo].arRecord.delegate = self;
    [Video shareVideo].arRecord.renderer.scene = self.sceneView.scene;
    [Video shareVideo].arRecord.needToSavedPhotosAlbum = YES; //是否保存到本地相册
    [Video shareVideo].arRecord.needCompress = NO;//是否压缩视频

AR Video Record Delegate:

    ///合成视频
    - (void)endMerge:(NSURL *)url;
    - (void)updateRecordingProgress:(CGFloat)progress;
    - (void)updateRecordState:(RecordState)recordState;

    #pragma mark - AR Video Record
    ///开始录制视频
    - (void)recordBegined;
    ///停止录制视频
    - (void)recordFinshed;
