App.vue中onlaunch下 plus.navigator.closeSplashscreen();
此方法关闭真机app打开时候的启动图，时间约6s

onLaunch: function() {
            //console.log('App Launch')
            switch (uni.getSystemInfoSync().platform) {
                case 'android':
                    //console.log('运行Android上') 
                    plus.navigator.closeSplashscreen();
                    break;
                case 'ios':
                    //console.log('运行iOS上') 
                    plus.navigator.closeSplashscreen();
                    break;
                default:
                    //console.log('运行在开发者工具上') 
                    break;
        }
    }
