// You need to firstly create trigger button. You can do this using block or your builder object which should conform to 'RHButtonViewConfigProtocol'
// RHTriggerButtonView allows you to change image for pressed state! 👌🏻
let triggerButton = RHTriggerButtonView(pressedImage: UIImage(named: "exit_icon")!) {
    $0.image = UIImage(named: "trigger_img")
    $0.hasShadow = true
}

// Then you need to create instance of SideButtons coordinator class with your View Controller view (it can be even TableView)
sideButtonsView = RHSideButtons(parentView: view, triggerButton: triggerButton)
sideButtonsView.delegate = self
sideButtonsView.dataSource = self

// When SideButtons controller is initialized properly you should set thier position in view in e.g. viewWillAppear method:
override func viewWillAppear(animated: Bool) {
    super.viewWillAppear(animated)

    sideBttns?.setTriggerButtonPosition(CGPoint(x: bounds.width - 85, y: bounds.height - 85))
}

//Finally you should create array of buttons which will feed our dataSource and Delegate methods :) e.g.:
let button_1 = RHButtonView {
    $0.image = UIImage(named: "icon_1")
    $0.hasShadow = true
}

let button_2 = RHButtonView {
    $0.image = UIImage(named: "icon_2")
    $0.hasShadow = true
}

let button_3 = RHButtonView {
    $0.image = UIImage(named: "icon_3")
    $0.hasShadow = true
}

buttonsArr.appendContentsOf([button_1, button_2, button_3])

//Similar as it is in TableView, now you should reload buttons with new values
sideButtonsView.reloadButtons()

func sideButtonsNumberOfButtons(sideButtons: RHSideButtons) -> Int
func sideButtons(sideButtons: RHSideButtons, buttonAtIndex index: Int) -> RHButtonView

func sideButtons(sideButtons: RHSideButtons, didSelectButtonAtIndex index: Int)
func sideButtons(sideButtons: RHSideButtons, didTriggerButtonChangeStateTo state: RHButtonState)

sideBttns?.setTriggerButtonPosition(25, y: frame.size.height - 85))
