Example

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

VRPicker is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod "VRPicker"

Usage

The VRPicker class is generic, and accepts one type parameter which must be a subclass of VRPickerItem. The type you pass in here will be your item class. VRPicker is instantiated with an instance of VRPickerConfiguration (which also accepts one type parameter), and a CGRect for frame:

struct PickerItem: VRPickerItem {
  let number: Int

  var description: String {
    return "(number) yrs"
  }
}

let config = VRPickerConfiguration<PickerItem>(items: ...)
let pickerView = VRPicker<PickerItem>(with: config, frame: .zero)

pickerView.didSelectItem = { item in
  print(item)
}

As done in the example above, the didSelectItem function property should be set to receive updates about which item is currently selected.

Configuration

VRPickerConfiguration, which is used when instantiating an instance of VRPicker, holds the various properties which can be configured.

All configuration properties have default values.

items: [T] (no default value)

The list of items to display in the picker. The items must conform to the protocol VRPickerItem, which extends CustomStringConvertible.

defaultSelectedIndex: Int (default value: 0)

Which index should be selected when the picker is initialized.

selectedFont: UIFont (default value: UIFont.boldSystemFont(ofSize: 20))

Which font to use for the currently selected item.

selectedFontColor: UIColor (default value: UIColor.white)

Which font color to use for the currently selected item.

nonSelectedFont: UIFont (default value: UIFont.systemFont(ofSize: 14))

Which font to use for the non-selected items.

nonSelectedFontColor: UIColor (default value: UIColor.black)

Which font color to use for the non-selected items.

selectionRadiusInPercent: Double (default value: 0.3)

The radius of the selection circle, in percent. (1.0 = 100 %)

selectionBackgroundColor: UIColor (default value: UIColor.green)

Which background color to use for the selection circle.

gradientColors: [UIColor] (default value: [UIColor.white.withAlphaComponent(0.8), UIColor.white.withAlphaComponent(0)])

An array of gradient colors to use for the left and right sides.

gradientWidthInPercent: Double (default value: 0.4)

The gradient width, in percent, of the entire picker width. (1.0 = 100 %)

gradientPosition: GradientPosition (default value: GradientPosition.above)

Which position to use for the gradients, above or below the items.

itemWidth: Int (default value: 100)

Which width, in points, to use for the items.

sliderVelocityCoefficient: Double (default value: 60)

Velocity coefficient for the scroll views.
