1.浏览一遍简易教程，下载相应的开发工具

写一个小例子

点击左侧的 “编辑”-》点击右侧代码里的 app.json 修改为

{
 "pages":[
  "pages/fightings/home", 
  "pages/publish/home", 
  "pages/mine/home"
 ],
 "tabBar": {
  "list": [
   {
    "pagePath": "pages/fightings/home",
    "text": "挑战"
   },
   {
    "pagePath": "pages/publish/home",
    "text": "发布"
   },
   {
    "pagePath": "pages/mine/home",
    "text": "我"
   }
  ]
 },
 "window":{
  "backgroundTextStyle":"light",
  "navigationBarBackgroundColor": "#fff",
  "navigationBarTitleText": "i挑战",
  "navigationBarTextStyle":"black"
 }
}

说明

pages就是我们有多少个页面
tabbar是页面底部的tab
window是页面的一些属性

这个样子太丑了我们先来美化一下这个tab

{
 "pages":[
  "pages/home/home",  
  "pages/fightings/home", 
  "pages/mine/home"
 ],
 "tabBar": {
  "color":"#666666",
  "selectedColor":"#f10b2e",

  "list": [
   {
    "pagePath": "pages/home/home",
    "text": "大厅",
    "iconPath": "./res/icon_tab_home.png",
    "selectedIconPath": "./res/icon_tab_home_hl.png"
    },
    {
    "pagePath": "pages/fightings/home",
    "text": "挑战",
    "iconPath":"./res/icon_tab_fighting.png",
    "selectedIconPath":"./res/icon_tab_fighting_hl.png"
   },

   {
    "pagePath": "pages/mine/home",
    "text": "我",
    "iconPath": "./res/icon_tab_me.png",
    "selectedIconPath": "./res/icon_tab_me_hl.png"
   }
  ]
 },
 "window":{
  "backgroundTextStyle":"light",
  "navigationBarBackgroundColor": "#fff",
  "navigationBarTitleText": "i挑战",
  "navigationBarTextStyle":"black"
 }
}

说明

字段都比较简单就不详细说了其中 “iconPath”: “./res/icon_tab_me.png”是图片的路径

自己在项目里创建一个res文件夹，然后放入需要的图片

tab 好看一点了吧
