Re: Displaying an "album of images" in iOS

Turns out there's an iCarousel framework that provides Cover Flow functionality.

Thanks to all!

Yes! Coverflow! That was the name of it!

Thanks for the pointer.

You could use a collection view if you just want a grid of thumbnails. If you 
want that coverflow sort of thing, Apple doesn’t supply a class for that these 
days, but there are many 3rd party implementations you could check out. Just 
search for “iOS coverflow” and I’m sure you’ll find many hits.

Displaying an "album of images" in iOS

[Carl Hoefs via Cocoa-dev]

I'm writing an iPhone app that analyzes an input image and generates nine jpg 
images. That's too many to be displayed at once on the GUI, so I thought to use 
an "album of images" that the user can thumb through (an animated display that 
used to be popular years ago on Finder, Safari, iTunes, etc). 

I can't find how to do this, either because I don't know the correct 
terminology for it, or because it's been deprecated many moons ago. Any ideas?

-Carl

I think, this is what must have happened in my case.
(It's just funny that it did not happen with one animation/layer, but with 
slightly different layers/animations it did happen.)

That seems to work like a charm!
Thanks a million for the pointer.
