Вопрос:
Мне нужна ваша помощь, чтобы проанализировать ответ, поступающий из API, и обновить раздел таблицы и строку на основе предпочтения порядка «колоды» ключей.
Прямо сейчас я создаю словарь значений ключа, группируя аналогичный тип «колоды», но после группировки последовательности колод, поступающей из ответа, изменяется, что приводит к неупорядоченному словарю.
Вот мой код:
func hitGetDVLData(dataDict: NSDictionary) {
APIsHandler.getDVLVideos(postData: dataDict) { (result, response, error, errorMessage) in
if let responseData = response {
if( error == nil amp;amp; (responseData["status"] as AnyObject) as? Bool ?? false){
if let responseData1 = responseData["data"] as? NSDictionary {
self.courseDataDict = responseData1 as! [String : Any]
if let topics = (responseData1["curriculam"] as? NSDictionary)?.value(forKey: "topics") as? [[String : Any]] {
// attached output below
self.totalArrayCount = topics.count
let crossReference = Dictionary(grouping: topics, by: { $0["deck"] as! String })
self.premimumVideoArray = [:]
self.premimumVideoArray = crossReference
// attached output below
}
self.tableviewHeightConstraint.constant = self.tableViewHeight
self.tableView.reloadData()
}
}
}
}
}
Где courseDataDict amp; premimumVideoArray — это переменная, определяемая следующим образом
var courseDataDict: [String : Any] = [:]
var premimumVideoArray : [String : [[String:Any]]] = [:]

Любой способ, как получить эти данные, чтобы моя последовательность группировки была в виде
[«Доклинические», «Параклинические», «Клинические (предварительные)», «Клинические», «SARPO»].
т.е. 1-й раздел — доклинические исследования и там строки, 2-й раздел — параклинические исследования и там строки, и так далее.
Заранее спасибо.

1. Словари по определению неупорядочены.
2. Сократите свой вопрос и удалите ненужную информацию. Мне кажется, что у вас уже есть ответ, используйте массив, который вы указали в конце, и выполните цикл по нему и получите значения из вашего словаря в этом порядке.
3. @JoakimDanielson Но как??
4. @Magnas да, но как мне это нужно в отсортированном виде.
Ответ №1:
Я бы посоветовал вам изучить и использовать Codable вместо этого для вашего декодирования json и работы со структурами, чтобы ваш код был понятнее и с ним было проще работать.
Предполагая, что вы это сделаете, и у вас будет пользовательский тип, подобный приведенному ниже (то, что вы опубликовали, не соответствует json, поэтому я сделал некоторые предположения)
struct Topic: Decodable {
let topicId: Int
let completed: String
let deck: String
let subImageUrl: String
let title: String
let total: Int
enum CodingKeys: String, CodingKey {
case topicId = "topic_id"
case subImageUrl = "sub_img_url"
case completed, deck, title, total
}
}
Затем мы можем обернуть эту структуру в другой пользовательский тип, который соответствует вашим требованиям пользовательского интерфейса, с именем deck (я называю их здесь section) и массивом тем
struct TopicSection {
let section: String
let topics: [Topic]
}
Итак, если у вас есть все ваши разделы из json в массиве topics , вы можете затем создать массив этой новой структуры, где содержимое поступает в порядке, указанном в вашем массиве названий разделов.
let sectionNames = ["Preclinicals", "Paraclinicals", "Clinicals (Prefinals)", "Clinicals", "SARPO"]
var sections = [TopicSection]()
sectionNames.forEach { name in
let section = TopicSection(section: name, topics: topics.filter { $0.deck == name})
sections.append(section)
}
И затем вы можете использовать sections массив в качестве источника для вашего табличного представления. Конечно, TopicSection также можно было бы использовать даже без использования Codable , изменив тип topics на словарь, [String: Any]
Комментарии:
1. Спасибо за это, но мои названия разделов являются динамическими.
2. @SatishThakur Тогда как вы определяете порядок сортировки?
3. @SatishThakur есть какие-нибудь отзывы по этому поводу?
