CPAnimationSequence

===================

**Describe multi-step animation sequences declaratively.**

Something like this:

	CPAnimationSequence* shakespeare = [CPAnimationSequence sequenceWithSteps:

		[CPAnimationStep           for:0.2 animate:^{ self.romeo.alpha = 1.0;

	                                                       self.julia.alpha = 1.0; }],

		[CPAnimationStep after:1.0 for:0.7 animate:^{

								CGPoint kiss = CGPointMake((self.romeo.center.x + self.julia.center.x)/2,

														   (self.romeo.center.y + self.julia.center.y)/2);

								self.romeo.center = kiss;

								self.julia.center = kiss;

		}],

		[CPAnimationStep after:2.0 for:0.5 animate:[self dramaticDeathAnimationStep]],

		[CPAnimationStep           for:0.0 animate:^{ self.theEnd.hidden = NO; }],

		nil];

	[shakespeare runAnimated:YES];

I described the rationale and possible improvements on the [compeople developer blog on Mobile Apps](http://blog.compeople.eu/apps/?p=43).

### CPAnimationProgram

With the addition of CPAnimationProgram, you can now also **run steps** (and sequences, and programs) **in parallel**, or **overlap** steps (and sequences, and programs).

This is still somewhat experimental, so you might run into problems with particularly complex overlaps. It does seem to work well, though, so give it a try.

### Composite pattern

The component implements the Composite design pattern, which means that you can **nest sequences and programs** as much as device memory and your sanity allow.

Requirements

-------

* CPAnimationSequence uses [ARC](http://developer.apple.com/library/ios/#releasenotes/ObjectiveC/RN-TransitioningToARC/_index.html). If your project doesn’t use ARC, set the `-fobjc-arc` compiler flag on the CPAnimationSequence source files.

* Deployment target iOS 4.3+ (The demo targets iOS 5.0, but is easily adapted for iOS 4.3).
