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

今天先到这里吧。。。
