How do I get the name of a UIButton after it has been pressed and compare it with an array of items?

The UIButton has an image view embedded within it. I want to apply image names to buttons and then take those names once a button has been pressed. When the UIButton and/or UIImage has been pressed I want to retrieve the name associated with that button/image and compare it with an array. Here is where I am at the moment:

enum Icon: String {
    case African = "african"
    case Buffet = "buffet"
    case Burger = "burger"
    case Chinese = "chinese"
    case Fries = "fries"
    case Grill = "grill"
    case IceCream = "icecream"
    case Japanese = "jap"
    case Mexican = "mex"
    case Pizza = "pizza"
    case Seafood = "seafood"
    case StreetFood = "streetfood"
    case Taj = "taj"
    case Turkey = "turkey"
    case Vegetarian = "vegetarian"
}


struct Food {
    let icon: UIImage?



init(foodCategories: [String: AnyObject]) {

    if let iconString = foodCategories["icon"] as? String {
        icon = foodImageFromIconString(iconString)
    }
}

func foodImageFromIconString(iconString: String) -> UIImage {
    var imageName: String

    if let iconValue = Icon(rawValue: iconString) {
        switch iconValue {
        case .African: imageName = "african"
        case .Buffet: imageName = "buffet"
        case .Burger: imageName = "burger"
        case .Chinese: imageName = "chinese"
        case .Fries: imageName = "fries"
        case .Grill: imageName = "grill"
        case .IceCream: imageName = "icecream"
        case .Japanese: imageName = "jap"
        case .Mexican: imageName = "mex"
        case .Pizza: imageName = "pizza"
        case .Seafood: imageName = "seafood"
        case .StreetFood: imageName = "streetfood"
        case .Taj: imageName = "taj"
        case .Turkey: imageName = "turkey"
        case .Vegetarian: imageName = "vegetarian"

        }
    }

    return UIImage(named: imageName)!

}
