Question

所以这就是我正在做的事情。制作了一个带有不同“骑行”的表，“骑行单元”都链接到一个pageControllerView，但我希望它们链接到关于那个特定骑行的静态信息（var）。这意味着每次点击桌面视图RideCell都会链接到存储在网页浏览中的特定“游乐设施”信息，而不是通用页面视图......

错误在Ride2上，并说“无法转换”，我确信它与信息[Page]组件相关，代码行的末尾：

    func setupRides() {

    let ride2 = Ride(title: "Contacts", route: "", image: #imageLiteral(resourceName: "main"), info: [tron])
//  let ride3 = Ride(title: "Pirates of the Caribbean", route: "Event", image: #imageLiteral(resourceName: "pirates"), info: [Page(title: "Pirates of the Caribbean", message: "Soaring Over the Horizon (FP)", imageName: "main")])

我只是试图让它在一个工作之前完成剩下的工作。

其他重要代码如下：

var tron: [Page] = {
let firstPage = Page(title: "Share a great listen", message: "It's free to send your books to the people in your life. Every recipient's first book is on us.", imageName: "main")
let secondPage = Page(title: "Send from your library", message: "Tap the More menu next to any book. Choose \"Send this Book\"", imageName: "main")
let thirdPage = Page(title: "Send from the player", message: "Tap the More menu in the upper corner. Choose \"Send this Book\"", imageName: "main")
return [firstPage, secondPage, thirdPage]
}()

这就是我的Ride和Page Classes的样子。

class Ride {
let title: String
let route: String
let image: UIImage
let info: [Page]

init(title: String, route: String, image: UIImage, info: [Page]){
    self.title = title
    self.route = route
    self.image = image
    self.info = info   
}
}

class Page {
let title: String
let message: String
let imageName: String

init(title: String, message: String, imageName: String) {
    self.title = title
    self.message = message
    self.imageName = imageName  
}
}

很抱歉，如果这是Noob问题。我做了RTFF，但还没找到......

Answer 1

tron是Page的数组，因为它被声明为[Page]。

执行[tron]时，您将tron放在另一个数组中。您现在拥有[[Page]]，这是Page的数组数组。

如此简单：

let ride2 = Ride(title: "Contacts", route: "", image: #imageLiteral(resourceName: "main"), info: tron)

无法将'[Page]'类型的值转换为预期的元素类型'Page'
