support more timing functions #52

Open kimon opened 10 years ago

kimon commented 10 years ago

CAMediaTimingFunction is limited to timing functions that can be modeled using a cubic-bezier curve. Add support for timing functions not otherwise expressible.

Ideally they are defined as blocks so it is easy to use custom timing function.

If you want a custom timing function implemented as a block, POPCustomAnimation supports that use case natively.
