Question

我想将我的项目（城市名称）分类为SplitViewController部分中的2个部分：国内和国际。

我在enum中使用dataModel并在init中使用MasterViewController这是我到目前为止所拥有的。

...的DataModel

import UIKit

enum welcomeImage {
    case austin, athens, barcelona, losAngeles, newYork, palmSprings, paris, portland, reykjavik, rome
}

class Destination {
    let name: String
    var description: String
    var destinationType: String
    let imageName: welcomeImage

    init(name: String, description: String, destinationType: String, imageName: welcomeImage) {
        self.name = name
        self.description = description
        self.destinationType = destinationType
        self.imageName = imageName

    }

func welcomeImage() -> UIImage? {
        switch self.imageName {
        case .athens:
            return UIImage(named: "Athens.jpg")
        case .austin:
            return UIImage(named: "Austin.jpg")
        case .barcelona:
            return UIImage(named: "Barcelona.jpg")
        case .losAngeles:
            return UIImage(named: "Los Angeles.jpg")
        case .newYork:
            return UIImage(named: "New York.jpg")
        case .palmSprings:
            return UIImage(named: "Palm Springs.jpg")

        }
    }

... MasterViewController

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)!

    self.cities.append(Destination(name: "Austin, Texas", description: "The lonestar state, BBQ and live music! Just watch out for the fire ants and always bring a bottle of water where ever you go.", destinationType: "", imageName: .austin))
    self.cities.append(Destination(name: "Athens, Greece", description: "The birthplace of democracy. The freshest food in Europe! Being in Athens, you get a genuine feeling of antiquity.", destinationType: "", imageName: .athens))
    self.cities.append(Destination(name: "Barcelona, Spain", description: "Home of Gaudi and the epic construciton of La Sagrada Familia. The croissants in Barcelona are actually better than those in Paris.", destinationType: "", imageName: .barcelona))
    self.cities.append(Destination(name: "Los Angeles, California", description: "San Gabriel mountains, swimming pools, palm trees, beaches and high-energy...", destinationType: "", imageName: .losAngeles))
    self.cities.append(Destination(name: "New York, New York", description: "The big apple", destinationType: "", imageName: .newYork))
    self.cities.append(Destination(name: "Palm Springs, California", description: "Warm Desert Breezes", destinationType: "", imageName: .palmSprings))
}

委派方法......

override func numberOfSections(in tableView: UITableView) -> Int {
        return 2
    }

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return self.cities.count
    }

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {        
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath) 
        let city = self.cities[indexPath.row]
        cell.textLabel?.text = city.name
        if let imageView = cell.imageView, let itemImage = city.welcomeImage() {
            imageView.image = itemImage
        } else {
            cell.imageView?.image = nil
        }
        return cell
    }

MasterViewController中的数组......

let sectionTitles: [String] = ["Domestic", "International"]

var domesticCity: [welcomeImage] = [.austin, .losAngeles, .newYork, .palmSprings]
var internationalCity: [welcomeImage] = [.athens, .barcelona]

我不确定将destinationType中的哪些内容放入tableView中将城市划分为国内和国际的相应部分。

感谢任何帮助。谢谢！

最简单的方法是为每个表部分填充数组。创建每个目标并将其添加到self.cities时，将destinationType设置为“Domestic”或“International”。完成self.cities后，创建self.domesticCities和self.internationalCities数组，并通过self.cities并将每个城市添加到正确的destinationType数组。

然后：

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if(section == 0){
            return self.domesticCities.count
        } else if(section == 1){
            return self.internationalCities.count
        }
        return 0; // should never get here
    }

同样适用于cellForRowAt。

我做同样的事情，根据名字的第一个字母组织联系人，并支持右侧拇指索引（或他们称之为的任何东西）。您可以使用带有destinationType“keys”的数组字典来管理多个部分，但只有两个部分可以显式定义数组。
