Hi all, first post to this mailing list. I'm trying to implement a simple Slideshow application on OS X using Macruby. It seems the normal way of doing this in Objective-C is by using the IKSlideshow class of Quartz framework. However I quickly started having crashes, even on the simplest example. Digging further I found this openradar from 2009 (http://openradar.appspot.com/7281441) stating that IKSlideshow doesn't work under GC. I tried taking the example app of IKSlideshow, enabling GC, and I confirmed it really crashes (Xcode 4.2, OS X 10.7.2). So since Macruby uses GC, I have no way of using IKSlideshow. So my question is, do anyone know an existing framework or sample code for showing fullscreen slideshows on OS X apps? Thanks everybody! Rúben -- Will work for bandwidth
