Question

为iOS开发应用程序，我创建了一个结构，并且还创建了一个充满结构对象的数组。结构flavors和descrip有两个属性。我想从数组中的每个项目中获取每个flavor属性，并使用它来填充表格视图单元格的标签。数组中有六个项目，所以我想要六个标签，以便它对应。所以标签应该是巧克力片，标签2蜂蜜，标签3糖，等等。所有建议和提示都非常感谢。

Import UIKit

class FlavorController: UIViewController, UITableViewDelegate, UITableViewDataSource {

@IBOutlet weak var flavorTable: UITableView!

struct cookieInfo {
    var flavor: String
    var descrip: String

}

var cookies = [cookieInfo(flavor: "Chocolate Chip", descrip: "Filled with gooey, milk chocholate! A classic!"), cookieInfo(flavor: "Honey", descrip: "Baked and drizzled with 100% pure honey, a must-have for sweet lovers!"), cookieInfo(flavor: "Sugar", descrip: "Simplicity meets savory, a sugar cookie topped with sweet icing!"), cookieInfo(flavor: "Peanut Butter", descrip: "A cookie infused with creamy peanut butter, the perfect cookie treat!"), cookieInfo(flavor: "Snickerdoodle", descrip: "Sugar cookie coated in cinnamon & sugar, baked to perfection!"),cookieInfo(flavor: "Shortbread", descrip: "An underrated yet flavorful cookie just like your grandma used to make!")]



func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
    return cookies.count

}

func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

public func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
    let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! FlavorCellTableViewCell

    //this is where I want to the text of each flavorLabel to be the flavor property of the struct
    cell.flavorLabel.text = ??

    return cell

}

这是简单的数组访问，后面只是字段访问。

let cookie = cookies[indexPath.row]
let flavor = cookie.flavor
cell.flavorLabel.text = flavor

或者更简单：

cell.flavorLabel.text = cookies[indexPath.row].flavor

从结构中获取属性并用作标签的最佳方法？
