Because you can't. These are the only properties you can animate:

Basically, I was thinking: Hey, why can't I use CABasicAnimation as a
means to animate just a value, not tied to a layer or a view, eg:
If my CABasicAnimation duration is 1 second, and it's fromValue = 0
and it's toValue = 1 and say the interval was 100 milliseconds
my value should increment by 0.10 every 100 milliseconds.
So at 5 seconds my value should be 0.50
Now I could use an NSTimer to do this same thing I suppose, but I
figured since Core Animation was already setup to handle things like
this, why not use that.
So my question is, is this even possible? Should I stop trying with
this approach? Not looking for a how do I do this, more of a yes or
no answer, I would like to figure it out on my own. Just want to make
sure I am not barking up the wrong tree to begin with.
