# Parallaxable

Beautiful parallax effect for your Table/Collection cells. (Or something else)

## Installation

Add

`pod 'Parallaxable'`

to your podfile, and run

`pod install`

## Usage

Out of the box, Parallaxable calculates parallax offset for any collection/table cell.

For enable calculation you need to set:

```swift

tableView.isParallaxEnabled = true

```

Also you need to conform protocol `Parallaxable` with your cell like: 

```swift

let parallaxOffsetMultiplier: CGFloat = 20

extension TableCell: Parallaxable {

    func updateVerticalParallaxOffset(with offset: CGFloat) {

        var targetCenter = contentView.center

        targetCenter.x = imageView.center.x

        targetCenter.y += offset * parallaxOffsetMultiplier

        imageView.center = targetCenter

    }

    func updateHorizontalParallaxOffset(with offset: CGFloat) {

        var targetCenter = contentView.center

        targetCenter.x += offset * parallaxOffsetMultiplier

        targetCenter.y = imageView.center.y

        imageView.center = targetCenter

    }

}

```

Code above will offset `TableCell`'s imageView from center by `offset`.

`offset` is value from `-1` to `1` representing position of cell relative to table/collection view's center.
