我这边是查阅材料,写了个JS版的函数:

  IOS_STOP_preventDefault() {    let startY, endY;    const scrollTop =      document.documentElement.scrollTop || document.body.scrollTop;    const clientHeight =      document.documentElement.clientHeight || document.body.clientHeight;    const scrollHeight =      document.documentElement.scrollHeight || document.body.scrollHeight;    document.addEventListener(      'touchstart',      function (e) {        startY = e.touches[0].pageY;      },      { passive: false }    );    document.addEventListener(      'touchmove',      function (e) {        endY = e.touches[0].pageY; //记录手指触摸的挪动中的坐标        //手指下滑,页面达到顶端不能持续下滑        if (endY > startY && scrollTop <= 0) {          e.preventDefault();        }        //手指上滑,页面达到底部不能持续上滑        if (endY < startY && scrollTop + clientHeight >= scrollHeight) {          e.preventDefault();        }      },      { passive: false }    );  }

当咱们判断以后环境是IOS环境时,在onload/onready/或各种框架生命周期里调用即可
