我正在使用Swift创建一个iOS应用,并正在使用来自GitHub的iCarousel(通过cocoapods安装),我不确定自己做错了什么,但是我似乎无法获得我设置为具有任何功能的iCarouselOptions效果...
我想要做的就是简单地更改轮播中UIView的间距(它们太靠近且重叠,这是我不希望的)。
这是我的代码:
import UIKit
import iCarousel
class MiniGamesViewController: UIViewController, iCarouselDelegate, iCarouselDataSource {
//Objects
@IBOutlet weak var leaveMinigamesButton: UIButton!
//Variables
var carouselHeight : CGFloat!
var selectionBallSize : CGFloat!
override func viewDidLoad() {
super.viewDidLoad()
leaveMinigamesButton.layer.zPosition = 3
carouselHeight = self.view.frame.size.height - 200
selectionBallSize = self.view.frame.size.width * 0.65
let carousel = iCarousel(frame: CGRect(
x: 0,
y: 100,
width: self.view.frame.size.width,
height: carouselHeight))
carousel.perspective = -0.005
carousel.centerItemWhenSelected = true
carousel.decelerationRate = 0.9
carousel.viewpointOffset = CGSize(width: 0, height: 0) //-selectionBallSize * 1.2
carousel.dataSource = self
carousel.type = .rotary
view.addSubview(carousel)
}
override func viewDidAppear(_ animated: Bool) {
setNeedsStatusBarAppearanceUpdate()
}
//This is how many items there will be in my rotary iCarousel
func numberOfItems(in carousel: iCarousel) -> Int {
return 6
}
//This defines each item or 'cell' in the iCarousel
func carousel(_ carousel: iCarousel, viewForItemAt index: Int, reusing view: UIView?) -> UIView {
let imageView: UIImageView
if view != nil {
imageView = view as! UIImageView
} else {
imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: selectionBallSize, height: selectionBallSize))
}
imageView.image = UIImage(named: "orbCyan")
return imageView
}
func carousel(_ carousel: iCarousel, valueFor option: iCarouselOption, withDefault value: CGFloat) -> CGFloat {
switch (option) {
case .spacing: return value * 2
case .radius: return 200
case .fadeMinAlpha: return 0.5
default: return value
}
}
}
具体来说,我代码的最底层是自定义的地方 应该可以生效,但是在我运行该应用程序时似乎并没有进行任何更改。此刻,我只关心尝试将轮播中的UIView隔开得更远。
我将iCarouselOptions函数放在正确的位置吗?甚至被“呼唤”吗?
感谢您的帮助!
答案 0 :(得分:1)
您不知道吗?我发布此问题后,立即发现问题哈哈(经过一天的尝试)。原来我错过了简单的一行:
carousel.delegate = self
在下面:
carousel.dataSource = self
这完全可以解决问题,现在可以正常工作了。我需要新鲜的眼睛:P
