LTHRadioButton

Slightly inspired by Google’s material radio button.

The clip below has 3 sections: full speed, 25% and 10%, but after converting it to GIF, it actually made it longer, so the 10% part takes a really long time. Here’s an mp4 link; try with Chrome if Safari doesn’t work - for me it doesn’t.

How to install

Manual

Drag LTHRadioButton.swift from the source folder into your Xcode project.

How to use

The initializer takes up to 3 params: a radius, a selectedColor, and a deselectedColor. All of them are optional:

  • radius defaults to 18
  • selectedColor defaults to a light blue
  • deselectedColor defaults to UIColor.lightGray

It doesn’t use Auto Layout internally, but after initialization it will have a proper size, so you can simply create constraints based on its frame.width and frame.height.

Properties

selectedColor and deselectedColor have been made publicly customizable for cases like a tableView with alternating row and radio colors, where the tableView might dequeue a cell with one color for displaying a cell with a different color.

isSelected - Indicates whether the radio button is selected.

Methods

init(radius: CGFloat = 18, selectedColor: UIColor? = nil, deselectedColor: UIColor? = nil) // Colors default internally if nil.
func select(animated: Bool = true) // Selects the radio button.
func deselect(animated: Bool = true) // Deselects the radio button.

Example

let radioButton = LTHRadioButton(selectedColor: .red)
container.addSubview(radioButton)

radioButton.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
  radioButton.centerYAnchor.constraint(equalTo: container.centerYAnchor),
  radioButton.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant: 16),
  radioButton.heightAnchor.constraint(equalToConstant: radioButton.frame.height),
  radioButton.widthAnchor.constraint(equalToConstant: radioButton.frame.width)]
)

[...]

radioButton.select()

[...]

radioButton.deselect(animated: false)
