微信小程序中自帶tabbar，我在app.json中配置了4個tabBar類似如下"tabBar": {    "color": "#9FB9BA",    "selectedColor": "#00AAA8",    "backgroundColor": "#1F2346",    "borderStyle": "white",    "position": "bottom",    "list": [{        "pagePath": "pages/exhibition/exhibition",        "text": "1",        "iconPath": "images/exhibition-white.png",        "selectedIconPath": "images/exhibition-active.png"    }, {        "pagePath": "pages/museum/museum",        "text": "2",        "iconPath": "images/museum-white.png",        "selectedIconPath": "images/museum-active.png"    }, {        "pagePath": "pages/spreadtrum/spreadtrum",        "text": "3",        "iconPath": "images/spreadtrum-white.png",        "selectedIconPath": "images/spreadtrum-active.png"    }, {        "pagePath": "pages/mine/mine",        "text": "4",        "iconPath": "images/mine-white.png",        "selectedIconPath": "images/mine-active.png"    }]}但是顯示出來缺和其他的小程序差很多，圖片一律81X81的請問是哪里寫錯了嗎，或者能否外部調(diào)試導(dǎo)航樣式，想要間距大一點(diǎn)，圖片小一點(diǎn)
