[PWA] Customize the Splash Screen of a PWA built with create-react-app _create

android displays a splash screen for PWAs based on the icons and names you provide, but ios just displays a solid color splash screen for installed PWAs by default.
We\'ll make a new splash screen image for every iOS device resolution size that we want to support, and then we can make a link tag in index.html to specify those images as the splash screen for each device resolution.
Also, make sure to remove background_color from the manifest - or it may overwrite the splash screen images on iOS.

For Splash screen, it use 512*512 image for Andorid.
For IOS we need to add image for splash screen, no other way around currently.

First, we must tell iOS that the app is apple-mobile-web-app-capable with a meta tag.

< meta name="apple-mobile-web-app-capable" content="yes">

Then we can specify each of those launch images as the image for that resolution.

< link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_640x1136.jpg" media="(device-width: 320px) and (device-height: 568px) and (-webkit-device-pixel-ratio: 2) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_750x1334.jpg" media="(device-width: 375px) and (device-height: 667px) and (-webkit-device-pixel-ratio: 2) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_1242x2208.jpg" media="(device-width: 414px) and (device-height: 736px) and (-webkit-device-pixel-ratio: 3) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_1125x2436.jpg" media="(device-width: 375px) and (device-height: 812px) and (-webkit-device-pixel-ratio: 3) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_1536x2048.jpg" media="(min-device-width: 768px) and (max-device-width: 1024px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_1668x2224.jpg" media="(min-device-width: 834px) and (max-device-width: 834px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: portrait)"> < link rel="apple-touch-startup-image" href="https://www.songbingjia.com/android/splash_2048x2732.jpg" media="(min-device-width: 1024px) and (max-device-width: 1024px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: portrait)">

Finally, in manifest.json, we have to actually remove the "background_color" setting first. Otherwise, that will override all of our images.
