Demo

HActionButton

Example

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

Installation

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

pod "HActionButton"
Swift version version
2.3 2.0.x
3.0 2.1.0 or later

Get Started

Add to view

You can either add HActionButton programmatically with code

let actionButton = HActionButton()
view.addSubview(actionButton)
// Customized configuration
// actionButton.mainButton.backgroundColor = UIColor.blueColor()
// actionButton.backgroundView.backgroundColor = UIColor.darkGrayColor()
// .
// .

or simply drag and drop an UIView in storyboard (Interface Builder) and set the class to HActionButton.

Implements DataSource and Delegate protocol

class ViewController: UIViewController, HActionButtonDataSource, HActionButtonDelegate{
    @IBOutlet weak var actionButton: HActionButton!
    // .
    // .
    // .
    override func viewDidLoad(){
        super.viewDidLoad() 
        actionButton.dataSource = self
        actionButton.delegate = self
        //.
        //.
        //.
    }
    // .
    // .
    // .
   // MARK: - HActionButtonDataSource
   func numberOfItemButtons(actionButton: HActionButton) -> Int {
       return 20
   }
   func actionButton(actionButton: HActionButton, itemButtonAtIndex index: Int) -> UIButton {
       // return circle button with random color by default
       return HActionButton.CircleItemButton(actionButton)

   }
   func actionButton(actionButton: HActionButton, relativeCenterPositionOfItemAtIndex index: Int) -> CGPoint{
       // return circle button with random color by default
       return HActionButton.EquallySpacedArcPosition(actionButton, atIndex: index, from: 0, to: 2 * M_PI)
   }

   // MARK: - HActionButtonDelegate
   func actionButton(actionButton: HActionButton, didClickItemButtonAtIndex index: Int) {
       actionButton.toggle()
       print("button (index) clicked")
   }
}

Now, your action button is supposed to work. Checkout the following parts to customize the action button.

Customize main button

The main action button can be customized by configure mainButton, which is defined in HActionButton class.

// swift 2.3
public var mainButton: UIButton!
// swift 3.0
open var mainButton: UIButton!

Protocols

HActionButtonDataSource

Implement to customize each item button.

class ViewController: UIViewController, HActionButtonDataSource{
    // .
    // .
    // .
   // MARK: - HActionButtonDataSource
   func numberOfItemButtons(actionButton: HActionButton) -> Int {
       return 20
   }
   // Optional
   func actionButton(actionButton: HActionButton, itemButtonAtIndex index: Int) -> UIButton {
       // return circle button with random color by default
       return HActionButton.CircleItemButton(actionButton)

   }
   // Optional
   func actionButton(actionButton: HActionButton, relativeCenterPositionOfItemAtIndex index: Int) -> CGPoint{
       // return circle button with random color by default
       return HActionButton.EquallySpacedArcPosition(actionButton, atIndex: index, from: 0, to: 2 * M_PI)
   }
}

HActionButtonDelegate

Implement to delegate the button action.

class ViewController: UIViewController, HActionButtonDataSource, HActionButtonDelegate{
    // .
    // .
    // .
   // MARK: - HActionButtonDelegate
   func actionButton(actionButton: HActionButton, didClickItemButtonAtIndex index: Int) {
       actionButton.toggle()
       print("button (index) clicked")
   }
   // Optional
   func actionButton(actionButton: HActionButton, didBecome active: Bool) {

   }
}

HActionButtonAnimationDelegate

Implement to customize the animation

class ViewController: UIViewController, HActionButtonDataSource, HActionButtonDelegate, HActionButtonAnimationDelegate{
    // .
    // .
    // .
   // MARK: - HActionButtonAnimationDelegate
   // Optional
   func actionButton(actionButton: HActionButton, animationTimeForStatus active: Bool) -> NSTimeInterval {
       // return 0.3 by default
       return active ? 2 : 0.3
   }
   // Optional
   func actionButton(actionButton: HActionButton, confugureMainButton mainButton: UIButton, forStatus active: Bool) {
       // rotate button with PI/2 back and forth for status by default
       HActionButton.RotateButton(mainButton, byAngle: M_PI/4, forStatus: active)
   }
   // Optional
   func actionButton(actionButton: HActionButton, confugureItemButton itemButton: UIButton, atIndex index: Int, forStatus active: Bool) {
       // set alpha of itemButton by default
       itemButton.alpha = CGFloat(active)
   }
   // Optional
   func actionButton(actionButton: HActionButton, confugureBackgroundView backgroundView: UIView, forStatus active: Bool) {
       // set alpha of backgroundView by default
       backgroundView.alpha = CGFloat(active)
       backgroundView.backgroundColor = UIColor(red: CGFloat(drand48()), green: CGFloat(drand48()), blue: CGFloat(drand48()), alpha: 0.4)
   }
}
