A generic customizable picker view based on UICollectionView.

CollectionPickerView

Generic and customizable picker based on UICollectionView. Picker cells are fully customizable.

Supports:

• Flat/wheel look.
• Snap to center after scroll.
• Both horizontal and vertical direction.

Fork of AKPickerView-Swift. Works in iOS 8.

Usage

Since this view is using UICollectionView internally you have to provide data same way as you would do with collection view (using dataSource). You can also use delegate if you want to handle item selection or underlaying UIScrollView callbacks. See example project for details.

Set the direction to vertical.

pickerView.isHorizontal = false

Disable wheel effect of the picker.

pickerView.isFlat = true

Prevent center selection when scrolling.

pickerView.selectCenter = false

Set spacing between cells, default 10.

pickerView.cellSpacing = 10

Set cell size (width for horizontal, height for vertical style), default 100.

pickerView.cellSize = 100

Set wheel effect perspective representation.

pickerView.viewDepth = 2000

Disable fading gradient mask.

pickerView.maskDisabled = true

Current selected index might be obtained from selectedIndex.

NSLog("\(pickerView.selectedIndex)")

And reload the picker view when any change in data set occurs.

pickerView.reloadData()
