如果设置了-webkit-overflow-scrolling: touch。iPhone是不会显示滚动条的。

    1. .van-list {
    2.     overflow-y: scroll;
    3.     -webkit-overflow-scrolling: auto;
    4. }
    5. .van-list::-webkit-scrollbar {
    6.     -webkit-appearance: none;
    7. }
    9. .van-list::-webkit-scrollbar:vertical {
    10.     width: 8px;
    11. }
    13. .van-list::-webkit-scrollbar:horizontal {
    14.     height: 11px;
    15. }
    17. .van-list::-webkit-scrollbar-thumb {
    18.     border-radius: 8px;
    19.     border: 2px solid white; /* should match background, can't be transparent */
    20.     background-color: rgba(0, 0, 0, .5);
