vue适配iphoneX底部安全区域

在index.html里面加代码

<meta name="viewport" content="width=device-width, initial-scale=1.0, viewport-fit=cover">

在底部吸底的控件那里处理一下

  .footer{
        width: 100%;
        /*height: 60px;*/
        padding-bottom: env(safe-area-inset-bottom);

        position: fixed;
        bottom: 0;
        background-color: #FFFFFF;
        box-shadow: 0 0 10px rgba(0,0,0,0.05);

        button{
            /*display: inline-block;*/
            display: block;
            width: 91.7%;
            height: 47px;
            margin: 7px 16px 6px 15px;
            background-color: #008CD6;
            border-radius: 5px;
            border: none;
            font-size: 18px;
            color: white;
            letter-spacing: 0.2px;
            text-align: center;

        }
    }
