iOS 设备上 DPlayer 无法切换 m3u8 视频清晰度问题？

Question

Dplayer在ios中切换清晰度卡住不动，视频格式是m3u8，安卓没有问题可以正常切换

 dp = new DPlayer({
                container: document.getElementById("dplayer"),
                autoplay: false,
                preload: "auto",
                video: {
                    quality: [此处是视频数据],
                    defaultQuality: 0,
                    //缩略图
                    thumbnails: "",
                    pic: res.data.image,
                    customType: {
                        customHls: (videoCus, player) => {
                            // 自定义类型：使用 Hls.js 播放 m3u8
                            const hls = new Hls();
                            hls.loadSource(player.quality.url);
                            hls.attachMedia(videoCus);
                        }
                    }
                },
