Gliding Collection is a smooth, flowing, customizable decision for a UICollectionView Swift Controller

Looking for developers for your project?
This project is maintained by Ramotion, Inc. We specialize in the designing and coding of custom UI for Mobile Apps and Websites.


The iPhone mockup available here.

Requirements

  • iOS 8.0+
  • Xcode 8
  • Swift 3 (<= 1.0.3)
  • Swift 4 (>= 1.1.0)

Installation

You can install GlidingCollection in several ways:

  • Add source files to your project.

pod 'GlidingCollection'

github "Ramotion/gliding-collection"

How to use

• Create a view controller class:

import GlidingCollection

class ViewController: UIViewController {
  let items = ["gloves", "boots", "bindings", "hoodie"]
}

• Drag a UIView onto the canvas. Change it's class to GlidingCollection and use autolayout constraints.

step-2

• Connect this view to your view controller class as an @IBOutlet.

@IBOutlet var glidingCollection: GlidingCollection!

• Make your view controller conform to GlidingCollectionDatasource. It's very similar to the UITableView or UICollectionView datasource protocols that you know:

extension ViewController: GlidingCollectionDatasource {

  func numberOfItems(in collection: GlidingCollection) -> Int {
    return items.count
  }

  func glidingCollection(_ collection: GlidingCollection, itemAtIndex index: Int) -> String {
    return "" + items[index]
  }

}

• Make your view controller conform to UICollectionViewDatasource:

extension ViewController: UICollectionViewDatasource {
  
  func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
    let section = glidingView.expandedItemIndex // Value of expanded section.
    return images[section].count
  }
  
  func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    guard let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "Cell", for: indexPath) as? CollectionCell else { return UICollectionViewCell() }
    // Configure and return your cell.
    return cell
  }
  
}

Customize

You can customize the appearance of GlidingCollection by overriding GlidingConfig's shared instance with your own.

var config = GlidingConfig.shared
config.buttonsFont = UIFont.boldSystemFont(ofSize: 22)
config.activeButtonColor = .black
config.inactiveButtonsColor = .lightGray
GlidingConfig.shared = config

🗒 All parameters with their descriptions are listed in GlidingConfig.


Notes

There is a GlidingCollectionDelegate protocol which can notify you when item in GlidingCollection didSelect, willExpand and didExpand.

If you want to achieve a parallax effect on a horizontal cards stack, you need to place your parallax view in a cell's contentView and set its tag to 99.

parallax-view

There is a kGlidingCollectionParallaxViewTag constant if you want to layout a cell in code.

imageView.tag = kGlidingCollectionParallaxViewTag
