Swift Animations made Easy

## Installation

- Add the following to your [`Podfile`](http://cocoapods.org/) and run `pod install`

```

    pod 'Fluent', '~> 0.1'

```

- or add the following to your [`Cartfile`](https://github.com/Carthage/Carthage) and run `carthage update`

```

    github "matthewcheok/Fluent"

```

- or clone as a git submodule,

- or just copy files in the ```Fluent``` folder into your project.

## Using Fluent

Fluent makes writing animations declarative and chainable.

```

boxView

.animate(0.5)

.rotate(0.5)

.scale(2)

.backgroundColor(.blueColor())

.waitThenAnimate(0.5)

.scale(1)

.backgroundColor(.redColor())

```

Simply call one of the animation methods, of which only `duration` is required:

- animate(duration: NSTimeInterval, velocity: CGFloat , damping: CGFloat, options: UIViewAnimationOptions) 

- waitThenAnimate(duration: NSTimeInterval, velocity: CGFloat , damping: CGFloat, options: UIViewAnimationOptions) 

All common properties on `UIView` are supported:

- scale(factor: CGFloat)

- translate(x: CGFloat, y: CGFloat)

- rotate(cycles: CGFloat)

- backgroundColor(color: UIColor) 

- alpha(alpha: CGFloat)

- frame(frame: CGRect)

- bounds(bounds: CGRect)

- center(center: CGPoint)

There are also relative versions of the transforms:

- scaleBy(factor: CGFloat)

- translateBy(x: CGFloat, y: CGFloat)

- rotateBy(cycles: CGFloat)

You may not mix absolute and relative transformations in the same animation.

### Using transforms

The order of the transformations are important!

To reverse the following:

```

boxView

.animate(1)

.translateBy(50, 50)

.rotateBy(0.5)

.scaleBy(2)

.backgroundColor(.blueColor())

.alpha(0.7)

```

We need to undo the transformations in reverse or get weird results:

```

boxView

.animate(1)

.scaleBy(0.5)

.rotateBy(-0.5)

.translateBy(-50, -50)

.backgroundColor(.redColor())

```
