uni-app自定义导航栏按钮|uniapp仿微信顶部导航条

<h3>uniApp原生导航栏</h3>
uni-app原生导航栏也能实现一些顶部自定义按钮+搜索框，只需在page.json里面做一些配置即可。设置app-plus，dcloud平台对app-plus做了详细说明：app-plus配置，不过目前暂支持H5、App端，不支持小程序。

 在page.json里配置app-plus即可
 
<div class="cnblogs_code">
<pre>{
"path": "pages/ucenter/index",
"style": {
 "navigationBarTitleText": "我的",
 "app-plus": {
 "titleNView": {
 "buttons": [
 {
 "text": "\ue670",
 "fontSrc": "/static/iconfont.ttf",
 "fontSize": "22px",
 "float": "left"
 },
 {
 "text": "\ue62c",
 "fontSrc": "/static/iconfont.ttf",
 "fontSize": "22px"

 }
 ],
 "searchInput":{
 ...
 }
 }
 }
}
},</pre>
</div>
那么如何监听按钮、输入框事件？ uni-app给出了相应API，只需把onNavigationBarButtonTap和onNavigationBarSearchInputChanged，写在相应的页面中即可。
uniApp自定义导航栏
 如何实现像淘宝、微信顶部导航栏，支持标题居左、居中、搜索条、按钮自定义。。。
将navigationStyle设为custom或titleNView设为false时，原生导航栏不显示，这时就能自定义导航栏
` "globalStyle": { "navigationStyle": "custom" } `
具体效果实例如下：

 这里要注意的是，H5、小程序、App端状态栏都不一样，需要重新计算处理，我这里已经处理好了，可直接使用，在App.vue里面设置即可
<div class="cnblogs_code">
<pre>onLaunch: function() {
uni.getSystemInfo({
 success:function(e){
 Vue.prototype.statusBar = e.statusBarHeight
 // #ifndef MP
 if(e.platform == 'android') {
 Vue.prototype.customBar = e.statusBarHeight + 50
 }else {
 Vue.prototype.customBar = e.statusBarHeight + 45
 }
 // #endif

 // #ifdef MP-WEIXIN
 let custom = wx.getMenuButtonBoundingClientRect()
 Vue.prototype.customBar = custom.bottom + custom.top - e.statusBarHeight
 // #endif

 // #ifdef MP-ALIPAY
 Vue.prototype.customBar = e.statusBarHeight + e.titleBarHeight
 // #endif
 }
})
},</pre>
</div>

 支持传入的属性，另外还用到了vue插槽slot
<div class="cnblogs_code">
<pre>/***
　　isBack 是否返回按钮
