    tips:
   <view class="item">1. image:图片链接地址，必须 https，请使用一张3x高清图。若设置了 image，则 title 参数失效</view>
   <view class="item">2. backgroundColor: 导航栏背景色，支持 16 进制颜色值</view>
   <view class="item">3. borderBottomColor: 导航栏底部边框颜色，支持16进制颜色值。若设置了 backgroundColor，borderBottomColor 会不生效，默认会和 backgroundColor 颜色一样。</view>
