I need to change the large app icon (512x512) for app store. I can't find how to to this through iTunes Connect. I's possible change the app screenshots though. I read the iTunes manual (page 97) and it says that it can be done but I only have the "choose file" button for screenshots, not for the large icon.
I am also confused because the same manual says on on page 99 that edit-ablity of the large icon is locked.
What am I missing?
Yes, editing of large icons that are already in use by iTunes Connect is locked, but however, You can still register a new update to Your app, in which You can upload Your new 1024*1024 icon
:)
Hi,
I think, no need to upload a new build. Sorry, it's in French, but I think you get it. You need to scroll a little bit but there you can upload an image file. Best is PNG and size 1024x1024.
I found out that you can change the large app icon if your app is not on sale yet - but the place to change it is well hidden.
1.click on the app in itunes connect
2.click on "view details"
3.click on "edit" button next to Version Information at the top of the page
4.scroll all the way down
5.change icon
I was confused, because I used to know the "upload icon" field from my iOS app, but did not see the field when I wanted to submit my Mac OS X desktop app.
The answer above indicates that you can upload an icon only for updates, which is true for iOS apps, but for Mac OS X apps, you can never upload a separate icon file, instead the 512 icon is uploaded together with your binary bundle:
"Note: You will not be asked to provide a large icon when adding your Mac OS X app because it will be uploaded later as part of the binary."
from p56 of https://itunesconnect.apple.com/docs/iTunesConnect_DeveloperGuide.pdf
To change the icon from one app-version to the next, after adding the new version to prepare for submission:
- Delete the previous icon by clicking the red (-) on the icon
- Save changes
- Refresh page, and you can choose file to add
Don't know why but after we delete the icon the link "Choose file" appears to be hidden, but if we save and then reload the page it shows up. Hope it helps
Also an issue I had was that the app was rejected and we wanted to update the icon before pushing a new version. In order to change the icon I had to remove the current build and then we could update the App Store Icon.
