使用的是vite + vue3的setup语法糖。

最终实现的效果为：

1.pages.json 中配置"navigationStyle": "custom"。以首页为例。

{
	"pages": [ 
		{
			"path": "pages/index/index",
			"style": {
				"navigationStyle": "custom",  //单个页面设置
				"navigationBarTitleText": "首页"
			}
		}
	],
	
	"globalStyle": {
        // 全局配置
		"navigationStyle": "custom"
	}
}

2.创建components目录，在components目录下创建navbar.vue组件

3.分析结构

顶部状态栏实际上分为两个部分，一个是系统状态栏，一个是状态栏的下方的内容区域。

大致就是图上两个部分。结构分出来后也就比较明了先要做啥了。

（1）获取顶部系统状态栏的高度

不同手机顶部的系统状态栏的高度是不一样的，可以通过方法uni.getSystemInfoSync() 获取顶部安全区域高度。拿到方法中的两个属性statusBarHeight,system。

const setNavSize = ()=>{
		const { statusBarHeight,system } = uni.getSystemInfoSync()
		status.value = statusBarHeight * 2
		const isIOS = system.indexOf('iOS') > -1
		if( !isIOS ){
			navHeight.value = 96  //非ios
		}else{
			navHeight.value = 88  //ios
		}
	}

由于iOS有刘海屏所以，iOS的内容高度为88。

（2）内容部分

首先当我们在主页时，出现主页的图标。

当我们主页有跳转内容时，点击跳转按钮进行跳转后，也就是当前不在主页页面，此时图标会变成返回图标。

HTML实现代码：

<!-- 内容 -->
		<view class="navbar" :style= " 'height:' + navHeight +'rpx;' + containerStyle">
			<view class="back-icon" @click="backHome">
				<image v-if="pages > 1" src="../../static/resource/navbar/ic_back.png" mode=""></image>
				<image v-else src="../../static/resource/navbar/ic_home.png" mode=""></image>
			</view>
			<view class="nav-title" v-if="titleText">
				<view :style=" 'height:' + navHeight + 'rpx;line-height:'+ navHeight + 'rpx;'+ textStyle ">{{titleText}}</view>
			</view>
		</view>

当页面有其他内容而不只是单单的图标时。

此时我们通过传入一个变量“isHome”配合v-if和v-else来实现该效果。

<view v-if="isHome" class="headNav" :style="'height:'+ navHeight + 'rpx;line-height:'+ navHeight + 'rpx;padding-left:20rpx'" >
			<text class="city">中部地区</text>
			<view style="flex:1">
				<navigator
					url="../../pages/search/index"
					:style=" 'height:'+ menu.height*2 + 'rpx;line-height:'+ menu.height*2 + 'rpx;margin-top:'+ (menu.top*2 - status) + 'rpx;margin-left:32rpx;margin-right:'+ (menu.width*2 + 24) + 'rpx;background:#f4f4f4;border-radius:200rpx;text-align:center'"
				>
					<text class="search-text">找医院</text>
				</navigator>
			</view>
		</view>
		<!-- 内容 -->
		<view v-else class="navbar" :style= " 'height:' + navHeight +'rpx;' + containerStyle">
			<view class="back-icon" @click="backHome">
				<image v-if="pages > 1" src="../../static/resource/navbar/ic_back.png" mode=""></image>
				<image v-else src="../../static/resource/navbar/ic_home.png" mode=""></image>
			</view>
			<view class="nav-title" v-if="titleText">
				<view :style=" 'height:' + navHeight + 'rpx;line-height:'+ navHeight + 'rpx;'+ textStyle ">{{titleText}}</view>
			</view>
		</view>

内容部分需要获取内容部分的高度，还需要知道胶囊的位置大小，从而来计算搜索框的大小。通过uni.getMenuButtonBoundingClientRect()来获取胶囊的位置大小。

整个的实现代码如下：

<template>
	<view class="nav">
		<!-- 状态栏 -->
		<view :style= "'height:' + status + 'rpx;' + containerStyle"></view>
		<view v-if="isHome" class="headNav" :style="'height:'+ navHeight + 'rpx;line-height:'+ navHeight + 'rpx;padding-left:20rpx'" >
			<text class="city">中部地区</text>
			<view style="flex:1">
				<navigator
					url="../../pages/search/index"
					:style=" 'height:'+ menu.height*2 + 'rpx;line-height:'+ menu.height*2 + 'rpx;margin-top:'+ (menu.top*2 - status) + 'rpx;margin-left:32rpx;margin-right:'+ (menu.width*2 + 24) + 'rpx;background:#f4f4f4;border-radius:200rpx;text-align:center'"
				>
					<text class="search-text">找医院</text>
				</navigator>
			</view>
		</view>
		<!-- 内容 -->
		<view v-else class="navbar" :style= " 'height:' + navHeight +'rpx;' + containerStyle">
			<view class="back-icon" @click="backHome">
				<image v-if="pages > 1" src="../../static/resource/navbar/ic_back.png" mode=""></image>
				<image v-else src="../../static/resource/navbar/ic_home.png" mode=""></image>
			</view>
			<view class="nav-title" v-if="titleText">
				<view :style=" 'height:' + navHeight + 'rpx;line-height:'+ navHeight + 'rpx;'+ textStyle ">{{titleText}}</view>
			</view>
		</view>
	</view>
</template>
