配置代码如下:

// step 0: 导入头文件
#import <SJVideoPlayer/SJVideoPlayer.h>
#import "SJFloatSmallViewTransitionController.h"

@interface SJFloatModeDemoViewController1 ()
@property (nonatomic, strong) SJVideoPlayer *player;
@property (nonatomic) NSInteger videoId;
@end

模式2: 在TableView或UICollectionView中播放时, 当播放器视图滑动消失时, 显示小浮窗视图
