iCheckbox

A custom checkbox component for iOS apps, written in Swift 3.0. Checkboxes can be ordered in one or two columns, can have solid borders with or without rounded corners, single or multiple selections, etc. iCheckbox works with iOS 8 and newer, also can be used in an Objective-C project.

See few examples:

Single selection, two columns, rounded corners solid border with title

Single selection, two columns, solid border with title

Single selection, two columns, no border

Multiple selections, single column, no border

Library offers checkbox/checkbox pool customization:

• Checkbox

  • Normal state title color
  • Selected state title color
  • Normal state image
  • Selected state image
  • Size

• Checkbox pool

  • Position on canvas
  • Selection type
  • Pool style
  • Border type
  • Border width
  • Border color
  • Border corner radius
  • Header title color

Install manually

1. Drag the iCheckbox.xcodeproj to your project. Go to app target’s settings, press the “+” under the Embedded Binaries section, and select the iCheckbox.framework
2. Add @import iCheckbox in your class.
3. That’s all.

Getting Started

Using iCheckbox is straightforward. Use iCheckboxBuilderConfig to create a configuration instance for the iCheckboxBuilder which will render checkboxes. iCheckboxBuilderConfig contains values to setup checkbox title color, checkbox states images, checkbox pool border, etc. Except iCheckboxBuilderConfig, iCheckboxBuilder takes a series of iCheckboxStates, each of them describing a checkbox, it’s title and selected state. To get notified when a checkbox is tapped, interested class must implement iCheckboxDelegate’s didSelectCheckbox() method.

Full example:

Swift

class ViewController: UIViewController, iCheckboxDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        addCheckboxes()
    }

    func addCheckboxes() {
        var checkboxBuilderConfig = iCheckboxBuilderConfig()
        checkboxBuilderConfig.headerTitle = "Some title"

        let checkboxBuilder = iCheckboxBuilder(withCanvas: self.view, andConfig: checkboxBuilderConfig)
        checkboxBuilder.delegate = self

        var firstCheckboxState = iCheckboxState()
        firstCheckboxState.title = "One"
        var secondCheckboxState = iCheckboxState()
        secondCheckboxState.title = "Two"
        var thirdCheckboxState = iCheckboxState()
        thirdCheckboxState.title = "Three"
        var fourthCheckboxState = iCheckboxState()
        fourthCheckboxState.title = "Four"
        var fifthCheckboxState = iCheckboxState()
        fifthCheckboxState.title = "Five"
        var sixthCheckboxState = iCheckboxState()
        sixthCheckboxState.title = "Six"
        var seventhCheckboxState = iCheckboxState()
        seventhCheckboxState.title = "Seven"
        checkboxBuilder.addCheckboxes(withStates: [firstCheckboxState,
                                                   secondCheckboxState,
                                                   thirdCheckboxState,
                                                   fourthCheckboxState,
                                                   fifthCheckboxState,
                                                   sixthCheckboxState,
                                                   seventhCheckboxState])
    }

    func didSelectCheckbox(withState state: Bool, identifier: Int, andTitle title: String) {
        print("Checkbox '\(title)', has selected state: \(state)")
    }
  }
