Tutorials ad infinitum

As I've mentioned in some other posts, I've been reading quite a few online tutorials lately.  In case you're curious, here's what I've been reading:

• The View Programming Guide for iOS - views are like invisible containers that sit in the application window and display everything that the user sees
• The OpenGL ES Programming Guide for iOS - as I may have mentioned before, OpenGL ES is a graphics library for making 2D and 3D animations... very powerful, and notoriously difficult to learn
• The Drawing and Printing Guide for iOS - I sort of skimmed through this one
• A really good OpenGL ES 2.0 tutorial by Ray Wenderlich that explains OpenGL ES from scratch

There was another site that listed OpenGL ES tutorials by platform and level of complexity that made for a helpful list (that's how I found Ray Wenderlich's stuff), but I can't seem to find my link to it... oh well.  I also glanced at a few other iOS guides on view controllers (they present, manage, and swap out the various views that a user will see during the life of the application), a guide on core animation, and a few other things on OpenGL ES, but I didn't dig into any of those too much, because I didn't feel like I was really learning the stuff that would allow me to dive in and start programming.

Finally, I've recently completed a read through the Sparrow Framework (game engine) documentation - they have really good manual and tutorial pages, and I like their philosophy a lot).  With that as a basis, I'm working my way through two online game tutorials that go start to finish using Sparrow:

• This action game programming tutorial on maniacdev.com which touts its simplicity, and...
• This four-part (and still growing) game tutorial - 1, 2, 3, 4 - posted on "the blog of a teenage programmer" called iKy1e iOS Developer, which looks to be slightly better, at first glance.

Just in case you wanted to follow along with what I'm reading.

More soon (including, hopefully, a sample app!)
