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:

tableView.isParallaxEnabled = true

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

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.
