我正在尝试在SKScene中使用iCarousel。问题是,当我拖动旋转木马时,它不会改变图像。我还没有在SpriteKit中找到iCarousel的教程,所以很多都是猜测。
这是我的代码:
import UIKit
import SpriteKit
class Hobbies: SKScene, iCarouselDelegate, iCarouselDataSource {
var carousel : iCarousel = iCarousel()
var imageArray : NSMutableArray = NSMutableArray()
override func didMove(to view: SKView) {
carousel.delegate = self
carousel.dataSource = self
carousel.type = .cylinder
carousel.center = CGPoint(x: self.size.width / 2, y: self.size.height / 2)
carousel.isUserInteractionEnabled = true
carousel.reloadData()
self.view?.addSubview(carousel)
}
func numberOfItems(in carousel: iCarousel) -> Int {
imageArray = ["Hobbies1.png", "Hobbies2.png", "Hobbies3.png"]
return imageArray.count
}
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
var imageview : UIImageView!
if view == nil {
imageview = UIImageView(frame: CGRect(x: 0, y: 0, width: 250, height: 250))
imageview.contentMode = .scaleAspectFit
} else {
imageview = view as! UIImageView
}
imageview.image = UIImage(named: "\(imageArray.object(at: index))")
return imageview
}
func carousel(_ carousel: iCarousel, valueFor option: iCarouselOption, withDefault value: CGFloat) -> CGFloat {
if option == iCarouselOption.spacing {
return value * 1.2
}
return value
}
}
iCarousel正在出现,但不会滚动。
我错过了什么?
使用自动滚动但不能正常滚动时,滚动会起作用。
