app启动后大概有几秒白屏,才会显示首页,下面介绍如何通过设置启动页来解决启动白屏问题：

config.xml配置

在cordova5.0版本以后，需要安装cordova-plugin-splashscreen插件以后才能修改和设置App的启动页面。

安装splashscreen插件：

cordova plugin add cordova-plugin-splashscreen
或
cordova plugin add https:
//github.com/apache/cordova-plugin-splashscreen.git

基本配置

然后在你的config.xml文件中，添加以下代码来设置APP的图标和启动页的图片：

其他配置

<preference name="SplashScreen" value="screen"/>

<preference name="ShowSplashScreenSpinner" value="false" />

<preference name="SplashShowOnlyFirstTime" value="false"/>

<preference name="AutoHideSplashScreen" value="false" />

<preference name="SplashScreenDelay" value="30000"/>

<preference name="FadeSplashScreen" value="false" />

若要使用启动页面淡入淡出的效果，则还需添加如下配置：

<preference name="FadeSplashScreen" value="true" />


<preference name="SplashMaintainAspectRatio" value="true"/>
<preference name="FadeSplashScreenDuration" value="500" />

隐藏启动页

splashscreen插件提供有以下两个方法：

navigator.splashscreen.hide();//隐藏启动页面

navigator.splashscreen.show();//显示启动页面

你可以在$ionicPlatform.ready中调用上面的hide方法，也可以引入$cordovaSplashScreen,然后使用$cordovaSplashScreen.hide()隐藏启动页。如果是ionic2则采用如下方式：
