Adding a startup image to a web app for iPad - ipad

I've tried adding a startup screen to my application, but it doesn't work (neither from Safari, nor from home screen).
<meta name="viewport" content="initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no"/>
<!-- Startup images -->
<!-- iOS iPad (retina, portrait) -->
<link rel="apple-touch-startup-image" media="(device-width: 1536px) and (orientation: portrait) and (-webkit-device-pixel-ratio: 2)" href="images/apple-touch-startup-image-1536x2008.png">
<!-- iOS iPad (retina, landscape) -->
<link rel="apple-touch-startup-image" media="(device-width: 1536px) and (orientation: landscape) and (-webkit-device-pixel-ratio: 2)" href="images/apple-touch-startup-image-1496x2048.png">
<!-- iOS iPad (portrait) -->
<link rel="apple-touch-startup-image" media="(device-width: 768px) and (orientation: portrait) and (-webkit-device-pixel-ratio: 1)" href="images/apple-touch-startup-image-768x1004.png">

I open it on iPad with retina display. All images are accessible, and load via direct links normally. All landscape images are in portrait format and rotated 90 degrees clockwise. I also tried setting "width" for retina to 2048, with no luck.
Is there anything I missed?

iOS WebApp not showing startup image

I added
<link rel="apple-touch-icon" href="favicon.png" />
<link rel="apple-touch-startup-image" href="splash-screen.png"/>
<meta name="apple-mobile-web-app-status-bar-style" content="black">
between the head tags of my website
but it doesn't work for the startup image
is this normal?
Are you trying to view the startup image in your desktop browser? If so then I would visit your website on an IOS mobile device and add the app to your homescreen. When you open it you should see the splash screen.
Splash screen are also tricky with different screen sizes. You can use the following code to ensure that it works.
<!-- IOS Touch Icons -->

It is quite tedious to generate all of these images so I would use a tool to generate the different icon and splash screen images automatically.
One such tool would be http://ticons.fokkezb.nl/
This functionality appears to have been broken since iOS 9.
Although there hasn't been any official word, this thread (and the lack of response from Apple) suggests it is possibly a bug.
The official documentation (last updated December 2016) still lists the apple-touch-startup-image feature so hopefully it will be fixed eventually.

iOS8 WebApp Splash Screen Black

I'm looking into adding a splash screen for a WebApp in iOS8, however I just get a black rectangle instead of the splash image. An example I found online suffers from the same problem. (As seen here.) I've tried both on an iPad Air and an iPhone 5s. Is this a known bug, or am I doing something wrong?

I was just working on a similar project: "building a WebApp" and went through the same headaches.
I have an iPhone 5S with iOS 8.1.1 and I just tested your third line with the 640px x 1096px picture successfully. I included once your whole code snippet and it worked aswell. I also went to your example page and it worked, too.
Unfortunately I don't have the link to the source, because I was just surfing the web but I can remember that one person had a problem with the line (your first line) for the iPhone 3. And as far as I can remember he had to put it at the end for no particular reason.
This is exactly the code I used for my test on line 3:
<link rel="apple-touch-startup-image"
href="https://s3.amazonaws.com/mikemai/assets/img/ios/h/apple-touch-startup-image-640x1096.png"
media="(device-width: 320px) and (device-height: 568px)
and (-webkit-device-pixel-ratio: 2)"/>
I would suggest to test it only with this line first and adding the rest step by step. Hope it helps to know that it works here :)
One last thought:
If you use a manifest file and you save the startup-image locally, you have to remove the WebApp and save to home screen again to reload the image or you have to update the manifest file aswell. Just in case the black rectangle got saved (not sure if it ever does).
In case you're interested, here is the meta for the title (keep it short):
<meta name="apple-mobile-web-app-title" content="Your WebApp Name" />

Web app with splash screen eventually prevents iOS from exiting the application and prevents restarting

I've found myself in an odd situation where I've set up Splash screens in iOS for a web app that I'm building and have found myself not being able to exit it after starting it up/closing/restarting it up a couple of times. This bug seems to also prevent rebooting also, I'm able to recreate this on both an iPad 3 and iPad mini and was wondering if someone else is aware of this?
Essentially in doing so, it's caused:
You can't exit the application by tapping the home button, or long pressing it
Can't power off the iPad by holding down the off button!
The screen won't turn off
I'm using the latest iOS for each and currently seem to be stuck waiting them both to run out of power!
Here's the code I have setup for displaying Splash screens:
<link href="images/touch/splash/splash-320x480.png" media="(device-width: 320px) and (device-height: 480px) and (-webkit-device-pixel-ratio: 1)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-640x960.png" media="(device-width: 320px) and (device-height: 480px) and (-webkit-device-pixel-ratio: 2)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-640x1136.png" media="(device-width: 320px) and (device-height: 568px) and (-webkit-device-pixel-ratio: 2)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-768x1024.png" media="(device-width: 768px) and (device-height: 1024px) and (orientation: portrait) and (-webkit-device-pixel-ratio: 1)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-1024x768.png" media="(device-width: 768px) and (device-height: 1024px) and (orientation: landscape) and (-webkit-device-pixel-ratio: 1)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-1536x2048.png" media="(device-width: 768px) and (device-height: 1024px) and (orientation: portrait) and (-webkit-device-pixel-ratio: 2)" rel="apple-touch-startup-image">
<link href="images/touch/splash/splash-2048x1636.png" media="(device-width: 768px) and (device-height: 1024px) and (orientation: landscape) and (-webkit-device-pixel-ratio: 2)" rel="apple-touch-startup-image">
I'm wondering if anybody else is able to recreate to confirm this issue? I wasn't seeing this until I added the Splash screens.
Edit: I was able to reset only by holding the power button and home button.
Edit 2: Now I've rebooted each of them I can't recreate the issue now. I'll keep trying but there doesn't seem to be any rhyme or reason as to what caused it on 2 separate devices.

iPad Web App Splash Screen Won't Work in Landscape Mode

I've read countless threads, blog posts, and other documentation online about this, yet I cannot get it to work. I've spent hours researching this and trying different things.
I'm trying to get a splash screen image to show for a web app on the iPad 2. I'm not even concerned with the iPad 3 resolution yet.
These are the tags that I have:
<link href="images/splash_748.png" media="screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:landscape)" rel="apple-touch-startup_image">
<link href="images/splash_768.png" media="screen and (min-device-width: 481px) and (max-device-width: 1024px) and (orientation:portrait)" rel="apple-touch-startup-image">
splash_748.png is 748x1024
splash_768.png is 768x1004
The portrait mode splash screen works just fine. The landscape version will not show. Does anyone have any ideas? I've tried over a dozen different ways to do this. None of them have worked.
I've been deleting the app and clearing Safari's cache each time I make an update. Then I go back to the web page and send it to the home screen. This seems to pick up changes in the images, so I can't imagine it's caching anything else.
Your code has a mistake in it. Look at the end of the first line
rel="apple-touch-startup_image"
it should be
rel="apple-touch-startup-image"
notice the _ should be a -

I think you have the Retina landscape dimensions backwards, should be: 2048x1496 not 1496x2048
