IOS打包后，navigationBar和tabbar不显示

IOS打包后，navigationBar和tabbar不显示，而且顶部状态栏的背景颜色也未变。Android没有问题。请问这是啥原因呀？
"tabBar": {
"color": "#7a7e83",
"selectedColor": "#ffffff",
"backgroundColor": "#26273e",
"list": [{
"pagePath": "pages/main/main",
"text": "设备",
"iconPath": "static/images/tabbar/tabbar_device.png",
"selectedIconPath": "static/images/tabbar/tabbar_device_choice.png"
}, {
"pagePath": "pages/map/map",
"text": "地图",
"iconPath": "static/images/tabbar/tabbar_map.png",
"selectedIconPath": "static/images/tabbar/tabbar_map_HL.png"
}, {
"pagePath": "pages/alarmlogs/alarmlogs",
"text": "预警",
"iconPath": "static/images/tabbar/tabbar_alarm.png",
"selectedIconPath": "static/images/tabbar/tabbar_alarm_HL.png"
}, {
"pagePath": "pages/user/user",
"text": "我的",
"iconPath": "static/images/tabbar/tabbar_user.png",
"selectedIconPath": "static/images/tabbar/tabbar_user_HL.png"
}]，
"globalStyle": {
"navigationBarTextStyle": "#ffffff",
"navigationBarBackgroundColor": "#2a2b44",
"backgroundColor": "#fbf9fe"
}
启动页为main，判断如果未登录会转到登录页，使用的是reLaunch，所以登录完成后转回main页也用的reLaunch
