[IOS] ImageView 翻圖片

裡面有用到兩種不同Array寫法來存圖片

class ViewController: UIViewController {
    @IBOutlet weak var btnPre: UIButton!
    @IBOutlet weak var btnNext: UIButton!
    @IBOutlet weak var labelName: UILabel!
    
    @IBOutlet weak var image: UIImageView!
    //兩種array方法
    var arrayImage = ["水上威尼斯","史特拉斯堡-2","科瑪", "新天鵝堡＿繽紛","春露"]
    
    var pic: [UIImage] = [
        UIImage(named: "水上威尼斯")!,
        UIImage(named: "史特拉斯堡-2")!,
        UIImage(named: "科瑪")!,
        UIImage(named: "新天鵝堡＿繽紛")!,
        UIImage(named: "春露")!
    ]
    var current:Int = 0
    var count:Int = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()
        count = arrayImage.count
        //image.image = UIImage(named: "水上威尼斯")
        image.image = pic[0]
        labelName.text = arrayImage[0]
        
    }
 
    @IBAction func preClick(_ sender: UIButton) {
        current -= 1
        if current < 0 {
            current = count - 1
        }
        //image.image = UIImage(named:String(arrayImage[current]))
        image.image = pic[current]
         labelName.text = arrayImage[current]
    }
    @IBAction func nextClick(_ sender: UIButton) {
        current += 1
        if current == count {
            current = 0
        }
        //image.image = UIImage(named:String(arrayImage[current]))
        image.image = pic[current]
 
        labelName.text = arrayImage[current]
 
    }
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
    }
}
