uniapp 内使用 nvue 做原生标题

nvue 页面只能使用 vue 的生命周期，uniapp 生命周期 api 支持部分，css 样式只支持 flex，很多 css 样式不支持

pages.josn 配置 nvue

vue 页面里获取 nvue 组件，使用

this.videoTitleNvue = uni.getSubNVueById('title');
this.videoTitleNvue.setStyle({
	top: 44 + uni.getSystemInfoSync().statusBarHeight + 'px',
	left: '0px',
	width: '100%',
	height: '40px'
});
this.videoTitleNvue.show('auto', 0, function() {
	// 打开后进行一些操作...
	//
});
