    height:60px;
  font-size:78px;
}

.scrollable {
  width:350px;
  white-space: nowrap;
  overflow-x:scroll;
  overflow-y:hidden;
}

.pop-up {
  position:fixed;
  height:300px;
  background:red;
  border: 1px solid #000;
  width:100%;
  top:0;
  overflow-y:scroll;
  z-index:9999;
}

.somemoretext {
  padding-top:600px;
}

谢谢你的帮助.

以下css修复了您的问题

html,body{height:100%}
body{background:red}
p {
  font-size:22px;
}

.item {
  display:inline-block;
  width:80px;
    height:60px;
  font-size:78px;
}

.scrollable {
  width:350px;
  white-space: nowrap;
  overflow-x:scroll;
  overflow-y:hidde;
  position: relative;
  -webkit-transform: translateZ(0);
}

.pop-up {
  position:fixed;
  height:300px;
  background:blue;
  border: 1px solid #000;
  width:100%;
  top:0;
  overflow-y:scroll;
  z-index:9999;
  -webkit-overflow-scrolling: touch;
}

.somemoretext {
  padding-top:600px;
}

包含-webkit-的行是在Safari中进行滚动工作的关键.
在.pop-up DIV中你需要overflow-y:scroll和-webkit-overflow-scrolling:touch来强制滚动.在.scrollableyou需要-webkit-transform:tranzlateZ(0); 要上下移动实际的html内容,其他方面DIV会滚动但溢出的内容不会显示.
