1. Solution

Add -webkit-overflow-scrolling: touch;
under the element that needs to be scrolled Give an example (can be pasted directly): 

<!DOCTYPE html><html lang="en"><head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>隐藏横向滚动条</title>
    <style>
    * {        
        margin: 0;        
        padding: 0;    
    }
    .cover {        
        width: 100%;        
        overflow: hidden;    
    }
    .father {        
        width: 100%;        
        padding: 0 10px;        
        background-color: #ff630c;        
        overflow-x: auto;        
        margin-top: -30px;        
        padding-bottom: 30px;        
        -webkit-transform: translateY(30px);        
        transform: translateY(30px);        
        box-sizing: border-box;    
    }
    .son {        
    width: 500%;        
    padding-bottom: 10px;    
    }

    .show {        
    width: 19%;        
    height: 60px;        
    background-color: #f00;        
    float: left;        
    margin-right: 5px;        
    text-align: center;    
    }

    .second {        
    width: 100%;        
    height: 50px;        
    background-color: #eee;        
    z-index: 100000;    
    }
    </style>
    <style>
    .father2 {        
    overflow-x: scroll;        
    width: 100%;        
    position: relative;        
    top: 10px;        
    margin-top: -10px;        
    -webkit-overflow-scrolling: touch;    
    }

    .son2 {        
    width: 500%;        
    padding-bottom: 10px;    
    }

    .show2 {        
    display: inline-block;        
    vertical-align: middle;        
    letter-spacing: -99999px;        
     text-align: center;        
     width: 19%;        
     margin-right: 10px;        
     height: 50px;        
     background-color: #f00;    
     }
     
    </style></head><body>
    <p class="cover">
        <p class="father">
            <p class="son">
                <p class="show">1</p>
                <p class="show">2</p>
                <p class="show">3</p>
                <p class="show">4</p>
                <p class="show">5</p>
            </p>
        </p>
    </p>
    <p class="cover">
        <p class="father2">
            <p class="son2">
                <p class="show2">1</p>
                <p class="show2">2</p>
                <p class="show2">3</p>
                <p class="show2">4</p>
                <p class="show2">5</p>
            </p>
        </p>
    </p>
    <p class="second"></p></body></html>

2. The reason

Horizontal scrolling is slow because Safari natively supports the -webkit- attribute, but the default is The rendering behavior in the browser causes lag when sliding. But after using this overflow-scrolling attribute, a native scrolling tab, native-scrolling control will be created, because the sliding degree will be very smooth~~~~As for the reason, students who are familiar with IOS may need to explore the native control. .
Compatibility: IOS5.0 or later.
