无法使用Xcode 9.4，SWIFT4.1在KASlideShow吊舱中加载图像

Question

我试图使用KASlideshow荚有一个淡入淡出动画在我的幻灯片，但图像没有显示在我的输出。我试图用我在堆栈溢出中看到的解决方案来解决这个问题，但是对我不起作用。

这是我的密码供你参考。请帮我解决这个问题。谢谢

类ViewController

class ViewController: UIViewController, KASlideShowDelegate, KASlideShowDataSource {
func slideShow(_ slideShow: KASlideShow!, objectAt index: UInt) -> NSObject! {
    return slideImages[0];
}

func slideShowImagesNumber(_ slideShow: KASlideShow!) -> UInt {
    return UInt(slideImages.count)
}

func slideShow(slideShow: KASlideShow, imageForPosition position: KASlideShowPosition) -> UIImage{
//missing code here
}

声明

@IBOutlet var whiteView: UIView!
@IBOutlet weak var slideShow: KASlideShow!

 var slideImages = [UIImage]()

viewDidLoad

override func viewDidLoad() {
    super.viewDidLoad()

     slideImages = [
        UIImage(named: "img1.png"),
        UIImage(named: "img3.png"),
        UIImage(named: "img5.png"),
        UIImage(named: "img6.png"),
        UIImage(named: "img8.png"),
        UIImage(named: "img9.png"),
        UIImage(named: "img11.png"),
        UIImage(named: "img12.png"),
        UIImage(named: "img13.png"),
        UIImage(named: "img14.png"),
        UIImage(named: "img15.png"),
        UIImage(named: "img16.png"),
        UIImage(named: "img17.png"),
        UIImage(named: "img18.png"),
        UIImage(named: "img19.png"),
        UIImage(named: "img21.png"),
        UIImage(named: "img22.png"),
        UIImage(named: "img23.png"),

        ] as! [UIImage]

    slideShow.delegate = self
    slideShow.datasource = self


    slideShow.delay = 1
    slideShow.transitionDuration = 0.5
    slideShow.transitionType = KASlideShowTransitionType.fade
    slideShow.imagesContentMode = .scaleAspectFill
    slideShow.add(KASlideShowGestureType.tap)


    slideShow.start()

KASlideShow代表

func kaSlideShowWillShowNext(slideshow: KASlideShow){
    NSLog("kaSlideShowWillShowNext")
}

/*func kaSlideShowWillShowPrevious(slideshow: KASlideShow){
    NSLog("kaSlideShowWillShowPrevious")
}

func kaSlideDidShowNext(slideshow: KASlideShow){
    NSLog("kaSlideDidShowNext")
}

func kaSlideShowDidShowPrevious(slideshow: KASlideShow){
    NSLog("kaSlideShowWillShowPrevious")
}
*/

you need to change datasource method and images array set only name like this

arrslideImages = ["test_1.jpeg","test_2.jpeg","test_3.jpeg"]

func slideShow(_ slideShow: KASlideShow!, objectAt index: UInt) -> NSObject! {

        let ind = NSInteger(index)
        return slideImages[ind] as NSObject;
    }
