客户最近发现选中原生tabbar的时候突然有个颜色，不知道从哪来的。而且说很多台手机也出现这样的状况。

json里的文件是这样的：

"tabBar": {

"color": "#8a8a8a",

"selectedColor": "#fc5051",

"borderStyle": "black",

"backgroundColor": "#FFFFFF",

"list": [

{

"pagePath": "pages/index/index",

"iconPath": "/images/tabbar/home1.png",

"selectedIconPath": "/images/tabbar/home.png",

"text": "首页"

},

{

"pagePath": "pages/goods/find/find",

"iconPath": "/images/tabbar/find1.png",

"selectedIconPath": "/images/tabbar/find.png",

"text": "发现"

},

{

"pagePath": "pages/goods/cart/cart",

"iconPath": "/images/tabbar/cart1.png",

"selectedIconPath": "/images/tabbar/cart.png",

"text": "购物车"

},

{

"pagePath": "pages/index/user/user",

"iconPath": "/images/tabbar/my1.png",

"selectedIconPath": "/images/tabbar/my.png",

"text": "会员中心"

}

]

}
