Hi Christ, sory for the late reply.
Here you have sprite with all PNG's included in the package: https://dl.dropbox.com/u/9963929/appdesignbox/hi-res_sprite.png
Included Xcode project provide working implementation of every UI element but only as a sample, not connected with business logic or data in the app.
Regarding your last screenshot (the one with progress bar, sliders, on/off switch), do you provide working implementation of those UI elements or just the sliced PNGs?
Could you provide another screenshot that shows most of the sliced PNGs? You can add watermark on it to protect your graphics, I want to see exactly what I'm getting
