iOS OTA install not registering custom URL scheme

Question

For one of our clients, we have developed an OTA app store for distribution.

To enable testing if the apps are installed, in each of the apps I wrote, I added two custom URL schemes: one that's just the app id, and one with the app id and the version (both with . replaced by -); so for example com-mycompany-app and com-mycompany-app-1-2-0 for com.mycompany.app, version 1.2.0.

Then, in our "app store" I just use [[UIApplication sharedApplication] canOpenUrl:] to determine if an App is installed or the latest version, and if so, replace the "Install" button with an "Open" button.

When installing the app through XCode, it works great. However, when I install the same app OTA, through my "app store", the canOpenUrl: call always returns NO. To see if it was a caching thing, I have tried restarting the "app store" app after OTA install has finished, but I get the same results.

Is this an issue with my manifest plist file? In the Info.plist that belongs to the target, the custom URL Scheme stuff is obviously there, but it's not in the manifest's. However, I would imagine it only uses the manifest to launch initial install...shouldn't the Info.plist be used during actual install to register these sorts of things? Is there something else I'm missing?

Thanks!

Edit: I'm using a custom build script to actually create the .ipa and .plist files that are being used for OTA distribution. I tried using iPhone Configuration Utility to install the IPA directly, and my app store was able to recognize those URLs as being openable. The only possible things I can think of are either that the plist I'm using to download & install needs to have some sort of reference to these custom URL schemes, or it's actually a legitimate bug in Apple's OTA framework.

Answer 1

I got this working, in case anyone is watching this or stumbles upon a similar issue.

The only thing I changed -- and there's no documentation saying the old way wouldn't or shouldn't work -- was to use periods in my URL scheme, instead of hyphens. So com-company-app:// became com.company.app:// (same as the bundle ID), and likewise with the version-appended one.

I don't know if my old URL schemes were violating official URL spec, or if you're supposed to use reverse-DNS, but everything is working, now.
