My last animation tutorial for now. This demo shows how to animate an image, in this case it’s a simple bouncing ball. There is nothing really new except this line.
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
which tells the animation to kind of speed up as it progresses. In this case it gives the effect of gravity since the ball speeds up as it gets closes to the bottom. This is not accurate but it makes it look better for the purpose of this demo.

This demo takes the first animation demo one step further. Since UIButton’s(and most control objects) are just UIView’s that can be animation just like the views. The first change is showing how you can animate a button just like the page flip and the second extends animation a little further. This shows some new commands for animation and how to fade views in and out. It also shows you how to execute commands after an animation has completed.
Demo Movie.

Being a developer I’m often contact by individuals and companies seeking advice and answers to their iPhone questions.

I’m posting this as my first tutorial because I know it was something that took me a while to figure out. Every example I looked at had too much other code in the project and I never really understood what was happening with just the animation. Well, here is the very basics of animation and page flipping. Download the code and build it to see how it works and play around with the different arguments to change the speed and animation effect.

Yeah, the holiday season is on it’s way and I’m sure it’s on a lot of other developers minds too…what can I make that will sell well over the holiday season. Well, since I’m too busy working on free applications I figured I would throw my ideas out there and see if anyone else picks up on them.
