Make a UICollectionView infinitely scrolling by looping through content

infinite-uicollectionview

This repository aims to provide a simple way of implementing an infinite collection view.
By infinite, we mean that as soon as a user reaches the boundary of the collection view content, the content will then loop back to the start in a circular manner.

Using InfiniteCollectionView

In order to use InfiniteCollectionView:

1. Make it the custom subclass of a UICollectionView component in your storyboard.
2. Set the infiniteDataSource (not the standard UICollectionView dataSource) and implement the required functions.

InfiniteCollectionViewDataSource

The custom datasource is very similar to the standard UICollectionViewDataSource. There are 3 functions to implement:

func cellForItemAtIndexPath(collectionView: UICollectionView, dequeueIndexPath: NSIndexPath, usableIndexPath: NSIndexPath) -> UICollectionViewCell

This function operates exactly the same as the regular cellForItemAtIndexPath, however, you should use dequeueIndexPath for dequeuing your cell and usableIndexPath for your content.

func numberOfItems(collectionView: UICollectionView) -> Int

As with the standard UICollectionViewDatasource, simply return the number of cells of content you have.

Current Support

You can use InfiniteCollectionView to scroll infinitely in a horizontal direction with equally sized cells.

Future

Improvements will include vertical scroll support and support for various cell sizes.

Feature request: Add license

Great library! Would love to use it in an app, but I don't see a license. What are usage rights for this?

How to get the correctly indexPath for [UICollectionView selectItemAtIndexPath:animated:scrollPosition:];

Its not working for ios 10.3.1

Cells are not loading in Ios 10.3.1

displaying only 2 element in RTL langauage

HI ,
This code is working fine in LTR language but not working for RTL language , just showing 2 cell
can you suggest me why?

Feature Request: Dynamic cell sizing based on control

A nice feature would be to have the cell dynamically resize to the width of controls within them i.e. the cell would wrap around the width of the label based on the text within it so each cell isn't the same

Feature Request: Centre cell

When a cell reaches the middle it could snap into the middle. Also on load the cells in the middle should be aligned in the middle.

setting Vertical Scroll direction not working

ISSUE: Unable to use infinitecollectionview class for multiple elements

It seems i’m unable to set the infiniteDataSource & infiniteDelegate delegate to another control in another VC file. Is it only possible to have one delegate set to one control in the VC file. There's no error but when the app builds and run it crashes when trying to set the delegates with the collectionview.

Issue: Prevent multiple cells from being selected

Preven multiple cells from being selected at the same time. If the user presses between two cells there can be issues when trying to get the index path.
