底部导航的设置

app.json里设置导航

 "tabBar": {
    "color": "#999",
    "selectedColor": "#51c3dd",
    "height": "99rpx",
    "borderStyle": "white",
    "backgroundColor": "#fff",
    "list": [    
      {
        "pagePath": "pages/index/index",
        "text": "首页",
        "iconPath": "./images/index.png",
        "selectedIconPath": "./images/index_active.png"
      },
      {        
        "pagePath": "pages/mine/mine",
        "text": "我的",
        "iconPath": "./images/mine.png",
        "selectedIconPath": "./images/mine_active.png"
      }
           
      
    ]
  }

底部导航的icon放到images里   ./images/aaa.png   .  放到服务器上会报错
