import UIKit

extension UIImage {
    public convenience init?(fromBundleWithClassName: AnyClass, imageNamed: String, withType: String) {
        let bundle = NSBundle(forClass: fromBundleWithClassName)
        let imagePath = bundle.pathForResource(imageNamed, ofType: withType)
        if let imgPath = imagePath {
            self.init(contentsOfFile: imgPath)
        } else {
            self.init(named: "")
        }
