未解决的标识符错误“ imageArray”

Question

为什么无法识别我的变量。它在第二个视图控制器上。

import UIKit 

class PacksPage: UIViewController {
    @IBOutlet weak var iCarouselView: iCarousel! 

    var imageArray = [ UIImage(named:"PeoplePack"),
                       UIImage(named:"MachineryPack"), 
                       UIImage(named:"ArchitecturePack") ,
                       UIImage(named:"MoneyPack"),
                       UIImage(named:"AnimalPack"), 
                       UIImage(named:"PrimitivePack") , 
                       UIImage(named:"GalacticPack") ]

    //...
} 

extension ViewController: iCarouselDelegate, iCarouselDataSource { 
    func numberOfitems(in carousel: iCarousel) —> Int { 
        return imageArray.count 
    }
}

Answer 1

出现此错误的原因是该变量在ViewController上不存在。您可以创建PacksPage viewController的扩展。

Answer 2

您应该使用

extension PacksPage: iCarouselDelegate, iCarouselDataSource

代替

extension ViewController: iCarouselDelegate, iCarouselDataSource

尝试一下并分享您的结果。
