入坑uni-app受不了自有组件极差的体验便自己写了个switch组件

uni-app坑不少，修改switch组件的原有样式在浏览器上能正常显示，但到了打包成APP后却不起作用；使用提供的方法style="transform:scale()只能按比例缩放，可定制性太差！这才打起自己写组件的念头，源码如下：

<template>
    <view>
        <view class="weui-switch" :class="{'weui-switch-on' : isChecked}" :value="value" @tap="toggle"></view>
    </view>
</template>
<script>
    export default {
        name: 'myswitch',
        props: {
          value: {
            type: Boolean,
            default: true
          }
        },
        data () {
            return {
                isChecked: this.value
            }
        },
        watch: {
          value (val) {
            this.isChecked = val
          },
          isChecked(val) {
            this.$emit('change', val);
          }
        },
        methods: {
          toggle() {
            this.isChecked = !this.isChecked;
          }
        }
    }    
</script>
<style>
    .weui-switch {
        display: block;
        position: relative;
        width: 94rpx;
        height: 45rpx;
        outline: 0;
        border-radius: 30rpx;
        box-sizing: border-box;
        background-color: #DFDFDF;
        transition: background-color 0.1s, border 0.1s;
        cursor: pointer;
    }
    .weui-switch:before {
        content: " ";
        position: absolute;
        top: 0;
        left: 0;
        width: 94rpx;
        height: 45rpx;
        border-radius: 30rpx;
        background-color: #3D424F;
        transition: transform 0.35s cubic-bezier(0.45, 1, 0.4, 1);
    }
    .weui-switch:after {
        content: " ";
        position: absolute;
        top: 2rpx;
        left: 4rpx;
        width: 40rpx;
        height: 40rpx;
        border-radius: 50%;
        background-color: #FFFFFF;
        box-shadow: 0 1px 3px rgba(0, 0, 0, 0.4);
        transition: transform 0.35s cubic-bezier(0.4, 0.4, 0.25, 1.35);
    }
    .weui-switch-on {
        border-color: #6F6F6F;
        background-color: #00F8E9;
    }
    .weui-switch-on:before {
        border-color: #1AAD19;
        background-color: #00F8E9;
    }
    .weui-switch-on:after {
        transform: translateX(48rpx);
    }
</style>

引入方法：通过绑定change事件监听组件的开关状态

 <myswitch v-model="item.state" @change="mywitch(item)"></myswitch>
