swift - 需要按 ObjectBulletin.id 对 tableview 进行排序

Question

我需要按 ObjectBulletin 中的 id 对我的 tableview 数据进行排序。我无法弄清楚如何对 id 进行排序并正确反射(reflect)数据。

我的结构

struct BulletinHelper: Codable {
    let limit: Int?
    let offset: Int?
    let objects: [ObjectBulletin]?
    let totalCount: Int?

    enum CodingKeys: String, CodingKey {
        case limit = "limit"
        case offset = "offset"
        case objects = "objects"
        case totalCount = "total_count"
    }
}

struct ObjectBulletin: Codable {
    let id: Int?
    let portalID: Int?
    let name: String?
    let size: Int?
    let height: JSONNullBulletin?
    let width: JSONNullBulletin?
    let encoding: JSONNullBulletin?
    let type: String?
    let objectExtension: String?
    let cloudKey: String?
    let s3URL: String?
    let friendlyURL: String?
    let altKey: String?
    let altKeyHash: String?
    let title: String?
    let meta: MetaBulletin?
    let created: Int?
    let updated: Int?
    let deletedAt: Int?
    let folderID: Int?
    let hidden: Bool?
    let cloudKeyHash: String?
    let archived: Bool?
    let altURL: String?
    let url: String?

    enum CodingKeys: String, CodingKey {
        case id = "id"
        case portalID = "portal_id"
        case name = "name"
        case size = "size"
        case height = "height"
        case width = "width"
        case encoding = "encoding"
        case type = "type"
        case objectExtension = "extension"
        case cloudKey = "cloud_key"
        case s3URL = "s3_url"
        case friendlyURL = "friendly_url"
        case altKey = "alt_key"
        case altKeyHash = "alt_key_hash"
        case title = "title"
        case meta = "meta"
        case created = "created"
        case updated = "updated"
        case deletedAt = "deleted_at"
        case folderID = "folder_id"
        case hidden = "hidden"
        case cloudKeyHash = "cloud_key_hash"
        case archived = "archived"
        case altURL = "alt_url"
        case url = "url"
    }
}

表格

var bulletins: BulletinHelper?

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "bullentinCell", for: indexPath)
    let files = bulletins?.objects![indexPath.row]
    cell.textLabel?.text = files?.name
    cell.detailTextLabel?.text = "Weekly Bulletin"

    return cell
}

我的排序尝试

它确实为我提供了排序的 ID，但我需要相关数据与其一起排序。

    let mysort: [Int] = [(bulletins?.objects![indexPath.row].id)!]
    let sortedlist = mysort.sorted()
    print(sortedlist)

Answer 1

根据@Kamran 的回复，我想出了这个按预期工作的解决方案。

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCell(withIdentifier: "bullentinCell", for: indexPath)
    let sortedlist = bulletins?.objects?.sorted(by: { ($0.id ?? 0) > ($1.id ?? 0) })
    let files = sortedlist![indexPath.row]
    cell.textLabel?.text = files.name
    cell.detailTextLabel?.text = "Weekly Bulletin"

    return cell
}
