In order for plugins that worked for Phonegap 2.9 (and under) to work with the new Phonegap 3.0, you have to add a plugin.xml to the plugin’s folder where the .m and .h files (for iOS) are located. You might need to edit the .m files for plugins built for iOS, as well.
To get an example of how the new plugin.xml file should look, check out this code I recently posted to GitHub for a Card.io credit card scanner plugin update: https://github.com/m140v/card.io-iOS-SDK-PhoneGap/blob/master/plugin.xml
Once you do this, you will also have to replace all the
(void)scan:(NSMutableArray *)args withDict:(NSMutableDictionary *)options
-type declarations with:
