A sequential animations without of creating a sequence action? #8

Sometimes it is not necessary to create a group object to run simultaneous animations. You can just create a lot of actions and call rz_runAction: for each of them. Is it possible to create something similar for sequences? I mean for example rz_runNextAction: which makes the animation passed to it to be called after all the currently existing animations or at once if it is a single action.

The benefit of using a group animation is that the completion block is called once all animations in the group finish (something difficult to do by calling the actions individually). I'm not sure why you would want to avoid using a sequence action. One nice thing about RZViewActions is that it avoids the need for global state. There is no easy way to handle the proposed rz_runNextAction: without knowing the global state of all in-flight animations. Therefore I don't believe such an API is within the scope of this library.

It's enough for me. I thought it is quite easy. The problem I describe is for example the following:

let we create UITableView which uses RZViewAction instead of usual default push/pop animation;
we want to allow user to perform push animation when the pop is not finished yet (instead of disabling of the user interaction until pop finishing).

I don't want to override this default behaviour, it is just an example. And I can't simply use "sequence" because I don't know even the count of RZViewAction objects before the animation starts. Or maybe you could suggest how to extend the current "sequence" in runtime

Ah, so you want to append an RZViewAction to an existing RZViewAction sequence while it is in-flight? If so, then I would like to add this to the API because I think it is a valuable addition. Feel free to either open a PR with the change, or I will get to it in the next day or so. Thanks!

@gerchicov-bp I have added this functionality in #9
