iCarousel

Question

所以我创建了一个 iCarousel 并且能够成功运行它。然而，我确实需要在 viewcontroller 上加载多个轮播。我找到了多个 iCarousels 代码并尝试将其改编为 Swift。不幸的是，现在我得到了一个 Thread1 信号 SIGABRT，它显示在行 "class AppDelegate" 上。真的不知道为什么要这样做。

请帮帮我！这是 ViewController

的代码

class ChangeRoomViewController: UIViewController, iCarouselDataSource, 
iCarouselDelegate {

    var hatsArray : NSMutableArray = NSMutableArray()
    var shirtsArray : NSMutableArray = NSMutableArray()

@IBOutlet weak var carousel1: iCarousel!
@IBOutlet weak var carousel2: iCarousel!

override func viewDidLoad() {

    super.viewDidLoad()

    hatsArray = ["TopHat.jpeg", "WhiteBrimHat.jpeg", "StoutHat.jpg", "BaseballCapBlackw:Red.jpg", "WhiteBaseballCap.jpg"]
    carousel1.type = iCarouselType.cylinder
    carousel1.reloadData()

    shirtsArray = ["StarWarsBlackFittedT.jpg", "CollaredFittedWhiteWithBeigeSplash.jpg", "CollaredWhiteWithZigzagLightBlueStripes.jpg", "ClooaredBlackWithWhiteStripes.jpg", "CollaredFittedNavyBlue.jpg"]
    carousel2.type = iCarouselType.cylinder
    carousel2.reloadData()
}

func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {

    var hatsView : UIImageView!
    var shirtsView : UIImageView!

    if view == nil {
        hatsView = UIImageView(frame: CGRect(x: 16, y: 65, width: 90, height: 60))
        hatsView.contentMode = .scaleAspectFit
        shirtsView = UIImageView(frame: CGRect(x: 16, y: 133, width: 90, height: 60))
        shirtsView.contentMode = .scaleAspectFit
    } else {
        hatsView = view as! UIImageView
        shirtsView = view as! UIImageView
    }

    hatsView.image = UIImage(named: "\(hatsArray.object(at: index))")
    shirtsView.image = UIImage(named: "\(shirtsArray.object(at: index))")

    if (carousel == carousel1) {
        return hatsView
    }else {
        return shirtsView
    }

}

func numberOfItems(in carousel: iCarousel) -> Int {
    if (carousel == carousel1) {
        return hatsArray.count
    }else {
        return shirtsArray.count
    }
}

}

我可以重现您的错误，这是由 shirtsArray 为空引起的，因此行

shirtsView.image = UIImage(named: "\(shirtsArray.object(at: index))")

导致您遇到的异常。

我不知道为什么，但是如果你移动这条线

    shirtsArray = ["StarWarsBlackFittedT.jpg", "CollaredFittedWhiteWithBeigeSplash.jpg", "CollaredWhiteWithZigzagLightBlueStripes.jpg", "ClooaredBlackWithWhiteStripes.jpg", "CollaredFittedNavyBlue.jpg"]

只要赋值给hatsArray，就可以了。

您的 viewForItemAt 函数有点乱。为什么要在决定需要哪一个之前为两个轮播创建 images/views？
