uni-app头部这个灰色怎么去除

uni-app头部这个灰色怎么去除，如果加"navigationStyle": "custom"，打包在手机上运行就会像图二一样和状态栏重叠，这种应该怎么搞呢

{
            "path": "pages/login/login",
            "style": {
                "navigationBarTitleText": ""
            }
        },

mainfest.json



"app-plus" : {
    "statusbar": {  
        "immersed": false  
    },
}
