ionic3 解决白屏

1、设置不自动隐藏splashscreen页面，设置最多延迟10s再关闭，这样可以不显示启动前的白画面

<preference name="AutoHideSplashScreen" value="false" />    <preference name="FadeSplashScreenDuration" value="5000" />    <preference name="ShowSplashScreen" value="true" />    <preference name="ShowSplashScreenSpinner" value="false" />    <preference name="SplashShowOnlyFirstTime" value="false" />    <preference name="FadeSplashScreen" value="true" />    

2、 <preference name="webviewbounce" value="false" />    <preference name="UIWebViewBounce" value="false" />    <preference name="DisallowOverscroll" value="true" />    <preference name="android-minSdkVersion" value="16" />  

3、<preference name="BackupWebStorage" value="none" />    <preference name="SplashMaintainAspectRatio" value="true" />    <preference name="SplashScreen" value="screen" />    <preference name="SplashScreenDelay" value="10000" />    <preference name="loadUrlTimeoutValue" value="700000" />

4、设置不显示载入的圆圈；<preference name="ShowSplashScreenSpinner" value="false" />

5、目录文件src/app 的app.component.ts中有来确保程序启动后关闭splashscreen页面（不用设置）platform.ready().then(() => { Splashscreen.hide(); });
