URL Schemes in iPhone application

I have an iPhone application which I wanted to add URL schemes to. The thing is that I have both a free version and a plus version.

What I would like to do is use the same scheme for both apps, but if the plus version is installed I want to the PLUS version to launch instead of the free version. Is that possible?

No. If multiple apps register for the same URL scheme, it is undefined which app will be activated by the OS. From the iOS Application Programming Guide:

Note: If multiple third-party applications register to handle the same URL scheme, it is undefined as to which of the applications is picked to handle URLs of that type.

Edit: just a thought how you might work around this issue: have your plus version register a second private URL scheme that you do not publish. Then, if your free app is launched from a URL, have it check whether the plus version is present and forward the passed URL to the plus version (via its private URL scheme).
