I’ve built this app in the style of iPhoneGUIExample, where the UI is built in Objective-C/IB and the code is running in openframeworks. I want to be able to swipe to switch background images, with the sketch running on top of it. The other thing is that I have some UI controls that need to run on top of the sketch, so the sketch really needs to be in between the background image and the controls. I’m sure I can probably hack some OF code into the sketch to get the swiping/background switching done, but so far I haven’t needed to go there and would prefer not to if necessary. Does anyone have any ideas, or should I just write this feature in OF alone? Thanks!
