A collection view subview for handling multiple continues touches on cells.

pod 'ContinuesTouchCollectionView'

• Swift 4.2+
• iOS 9.0+

• Create a ContinuesTouchCollectionView instance and populate ContinuesTouchCollectionViewCells on it.
• You can set isLocked property to true for disabling the scrolling on collection view and enabling multiple continues touches.
• When you are populating your cells, set ContinuesTouchCollectionViewCellDelegate of the cell, to the view controller you are working on.
• Get informed when your cells started or stopped being touched with the delegate methods.

public protocol ContinuesTouchCollectionViewCellDelegate: class {
  func continuesTouchCollectionViewCellDidStartTouching(_ cell: ContinuesTouchCollectionViewCell)
  func continuesTouchCollectionViewCellDidStopTouching(_ cell: ContinuesTouchCollectionViewCell)
}

• You may also override isTouching property inside your cell class in order to make it responding highlight colors.
• Use isTouching instead of isHihglighed property.

override var isTouching: Bool {
  didSet {
    backgroundColor = isTouching ? .lightGray : .darkGray
  }
}

• Check out the example project for the implementation.

This library is used in my app ScaleBud (iOS, AUv3) in the app store, check it out!
