After searching a bit in the forum I want to ask something about Xcode. I made an simple application in Quartz Composer and included a mouse button event and a remote control with TouchOSC to start and stop a (visual)timer. Now I'm trying to convert it to an app in Xcode. So that the app can run on other Mac's. I've included the Quartz framework and tried to ad more frameworks but application does not work proper. It will start but it will not react to any mouse event (buttons) nor the TouchOSC commands. I think I need to include some more files but I'm not sure. Has anyone build apps from just Quartz Composer compositions?
