Swift xcode 错误："Row.Type has no subscript members"

Question

我正在尝试创建一个包含 12 行的表，当您单击一行时，它会将用户传输到带有按钮列表的新窗口。

我收到错误的类：

行类：

import UIKit

let rows = [
    Row(FileName: "File slot 1",
        QuartzImage: "Image slot 1"),
    Row(FileName: "File slot 2",
        QuartzImage: "Image slot 2"),
    Row(FileName: "File slot 3",
        QuartzImage: "Image slot 3"),
    Row(FileName: "File slot 4",
        QuartzImage: "Image slot 4"),
    Row(FileName: "File slot 5",
        QuartzImage: "Image slot 5"),
    Row(FileName: "File slot 6",
        QuartzImage: "Image slot 6"),
    Row(FileName: "File slot 7",
        QuartzImage: "Image slot 7"),
    Row(FileName: "File slot 8",
        QuartzImage: "Image slot 8"),
    Row(FileName: "File slot 9",
        QuartzImage: "Image slot 9"),
    Row(FileName: "File slot 10",
        QuartzImage: "Image slot 10"),
    Row(FileName: "File slot 11",
        QuartzImage: "Image slot 11"),
    Row(FileName: "File slot 12",
        QuartzImage: "Image slot 12")]
class Row
{
    ///// enum Type: String {
    // }
    var FileName: String
    var QuartzImage: String
    // var type: Type
    // var shortDescription: String
    // var longDescription: String
    init(FileName: String, QuartzImage: String) {
        self.FileName = FileName
        self.QuartzImage = QuartzImage
}
}

Answer 1

使用：let filename = rows[indexPath.row].FileName而不是通过密钥访问。

此外，通常属性声明为骆驼大小写从较低开始，即：fileName和quartzImage
