Suggestion at SnapKit about dkchainableanimationkit HOT 3 CLOSED

YES, it is really interesting. When I found the animation syntax is so concise and elegant. I have tried to use this syntax to set up UIKit component ChainableKit But it is a little weird. I think this syntax works well with animation but not such well with UIKit.

The suggestion is also very great. And it still needs much more work... I will try it figure it out and see whether it is better way to add constraint to UIKit component.

Thanks so much.

ChainableKit looks really good.

I'm trying to think about what would be the most concise, DRY, and readable syntax, which combines setting properties, animating and constraints (and animating constraints).

To produce this:

.. you could have something like this:

var greenView = UIView()
greenView.set.backgroundColor(UIColor.greenColor()).alpha(0.5) // 'set' to chain properties
view.addSubview(greenView)
greenView.constrain.top.bottom.left.equalTo(view) // 'constrain' to make (and chain) constraints 
greenView.constrain.width.equalTo(view).multipliedBy(0.25)

var redView = UIView(frame:CGRectMake(0, 0, 100, 100))
redView.backgroundColor = UIColor.redColor()
view.addSubview(redView)

greenView.constrain.width.equalTo(view).multipliedBy(0.5).spring.animate(1.0) {
    self.greenView.animate.alpha(1.0).animate(1.0).
    self.redView.animate.moveXY(200,200).delay(0.5).spring.animate(0.5)
}

That’s about 10 lines, 620 characters.

If done without any libraries - https://gist.github.com/cannyboy/dabe7a9f487338e07830 - it would be maybe 40 lines - about 2500 characters.

@cannyboy I responded to your issue on SnapKit. There are some reasons that that syntax wont work (or at least it would be very difficult to make it work). I am thinking of adding a chainable property that takes a NSLayoutContraint and a value and animates the change of the constant.

So if you use SnapKit or Masonry to reference a constraint you could then say

self.myView.makeConstraint(self.myConstraint, 50).animate(1.0);

I just want to make sure this works 100% of the time and conforms to apples API.
