Ionic3 启动页以及应用图标

1. 将新的启动页和应用图标图片（最好是高清png）上传到根目录 resources
2. 使用命令自动生成，通过CMD进入项目所在文件夹，分别执行

   ionic cordova resources android  

   ionic cordova resources ios

   图片规格：The source image for icons should ideally be at least 1024x1024px and located at resources/icon.png. The source image for splash screens should ideally be at least 2732x2732px and located at resources/splash.png. If you used ionic start, there should already be default Ionic resources in the resources/ directory, which you can overwrite.

   前置条件：This command uses Ionic servers, so we require you to be logged into your free Ionic account. Use ionic login to login.

    

3. 检查根目录下config.xml

   配置项：
   SplashScreenDelay：单位毫秒，默认3秒，启动页隐藏事件

   
   

4. 结束，运行下看看
