1、在pages.json中，给对应的页面设置自定义导航栏样式

    {
      "path": "pages/index/index",
      "style": {
        "navigationStyle": "custom",
        "navigationBarTextStyle": "white",
         "navigationBarTitleText": "首页",
      }
    },

2、定义自定义组件customNavbar,在组件中获取屏幕边界到安全区域的距离

<template>
  <view class="navbar" :style="{paddingTop:safeAreaInsets?.top+'px'}">
	<view class="logo">
		<image src="../../static/c1.png" mode=""></image>
		<text>头部导航</text>
	</view>
  >
  <view>
  	<text class="icon-search">搜索</text>
	<text class="icon-scan"></text>
  </view>
  </view>
</template>
<script lang="ts" setup>
const {safeAreaInsets} =uni.getSystemInfoAsync()

console.log(safeAreaInsets)

</script>
