Button not rotating when tapped after setting background Image?

[gabhisekdev]

I am using your frame work for implementing floating action button. I tried to use an image for the button by setting actionButton.setImage = "".*The problem now is the button is not rotating as it was earlier. Any idea??

    ```

let twitterImage = UIImage(named: "twitter_icon.png")!
let plusImage = UIImage(named: "googleplus_icon.png")!

    let twitter = ActionButtonItem(title: "Twitter", image: twitterImage)
    twitter.action = { item in print("Twitter...") }

    let google = ActionButtonItem(title: "Google Plus", image: plusImage)
    google.action = { item in print("Google Plus...") }

    actionButton = ActionButton(attachedToView: self.view, items: [twitter, google])
    actionButton.action = { button in button.toggleMenu() }
    actionButton.setImage(UIImage(named: "bottom-logo-icon.png")!, forState: .Normal)
    actionButton.backgroundColor = UIColor.clearColor()
