Present real view controller in the preview

[hansstefan]

Instead of making a screenshot of a view controller at the begining and presenting a screenshot in the preview, you can present a viewController itself in the preview and make a screenshot of it at the commit. This screenshot is for smooth animation purpose only. The advantage is that if you have a content which is loaded from the server then it is loaded in the preview, just like in the original 3d Touch PeekPop. Below is the effect I was able to get.

Thanks @hansstefan.

I originally considered doing this but in my own tests I got very poor performance on iOS8 iPhone 4S.

I appreciate the pull request but will need to do some more testing before deciding on the next step...

I have just tested on iphone 4S with ios 8. Performance regarding showing the viewController is very good. The only problem is the delay caused by the blur calculations.

And by the way, have you thought about using UIPercentDrivenInteractiveTransition. It has a lot of similarity to what is needed.

Aw, so this is the issue I'm running into. Just got everything working for my 3D Touch device, and briefly touched on a non 3D touch device. Planned on diving into this more tomorrow.

+1 absolutely needed, even if we need to lay off of the crazy performance-heavy tasks. I'd say, at least, make things configurable and we can choose how to roll on our end. Not a massive deal as I'll just fork it myself. Just a thought/vote.

Thanks @mcgraw and @hansstefan. There's definitely a valid use case for using the full view controller but it should definitely be configurable (and in my opinion, not the default configuration). I'll work on an update.

Is there any progress on this? Would need that for previewing server generated data.

@michelalbers Check my pull request. The code is here:
