Set server MIME types
You may need to congure your web server so the manifest le and app le are
transmitted correctly.
For OS X Server, add the following MIME types to the web service’s MIME Types settings:
application/octet-stream ipa
text/xml plist
For IIS, use IIS Manager to add the MIME type in the Properties page of the server:
.ipa application/octet-stream
.plist te
xt/xml
Troubleshoot wireless app distribution
If wireless app distribution fails with an “unable to download” message:
•
Make sure the app is signed correctly. Test it by installing it on a device using Apple
Congurator, and see if any errors occur.
•
Make sure the link to the manifest le is correct and the manifest le is accessible to
web users.
•
Make sure the URL to the .ipa le (in the manifest le) is correct and the .ipa le is accessible
to web users over HTTPS.
Network conguration requirements
If the devices are connected to a closed internal network, you should let iOS devices access the
following:
•
ax.init.itunes.apple.com: The device obtains the current le-size limit for downloading apps
over the cellular network. If this website isn’t reachable, installation may fail.
•
ocsp.apple.com: The device contacts this website to check the status of the distribution
certicate used to sign the provisioning prole.
Provide updated apps
Apps you distribute yourself aren’t automatically updated. When you have a new version for
users to install, notify them of the update and instruct them to install the app. Consider having
the app check for updates and notify the user when it opens. If you’re using wireless app
distribution, the notication can provide a link to the manifest le of the updated app.
If you want users to keep the app’s data stored on their device, make sure the new version uses
the same bundle identier as the one it’s replacing, and tell users not to delete their old version
before installing the new one. The new version replaces the old one and keeps data stored on
the device, if the bundle identiers match.
Distribution provisioning proles expire 12 months after they’re issued. After the expiration date,
the prole is removed and the app won’t launch.
Before a provisioning prole expires, go to the iOS Dev Center website to create a new prole for
the app. Create a new app archive (.ipa) with the new provisioning prole, for users installing the
app for the rst time.
