如何解决在 collectionview 中搜索具有多个部分的数据模型
我的 API 响应如下：

{
"movie_category": "Comedy","movie_category_code": "comedy","movie_list": [
{
"name": "Dhamaal","description": "Four lazy slacker conmen buddies who are jobless,homeless and broke learn about the secret of a hidden treasure from a dying thief and later embark on a race against time to find the mobster's buried treasure and claim it while being pursued by a determined police inspector who is hellbent to get the treasure all by himself.","release_year": "2007-09-07 07:00:00","movie_banner": "http:\/\/apis.dev.ganniti.com\/assets\/images\/dhamaal.jpg","movie_icon": "http:\/\/apis.dev.ganniti.com\/assets\/images\/dhamaal.jpg","ratings": "3.7","theatre_locations": [

}
它的模型类如下：
import Foundation
// MARK: - MovieModel
struct MovieModel: Codable,Equatable {
static func == (lhs: MovieModel,rhs: MovieModel) -> Bool {
return false
}
let success: Bool
let message: String
var data: [Datum]
}
// MARK: - Datum
struct Datum: Codable,Equatable {
static func == (lhs: Datum,rhs: Datum) -> Bool {
return false
}
let movieCategory,movieCategoryCode: String
let movieList: [MovieList]
enum CodingKeys: String,CodingKey {
case movieCategory = "movie_category"
case movieCategoryCode = "movie_category_code"
case movieList = "movie_list"
}
}
// MARK: - MovieList
struct MovieList: Codable,Equatable {
static func == (lhs: MovieList,rhs: MovieList) -> Bool {
return false
}
let name,movieListDescription,releaseYear: String?
let movieBanner,movieIcon: String?
let ratings: String?
let theatreLocations: [TheatreLocation]
enum CodingKeys: String,CodingKey {
case name
case movieListDescription = "description"
case releaseYear = "release_year"
case movieBanner = "movie_banner"
case movieIcon = "movie_icon"
case ratings
case theatreLocations = "theatre_locations"
}
}
// MARK: - TheatreLocation
struct TheatreLocation: Codable {
let latitude,longitude: String?
}
来自 API 的这些数据将显示在多个部分和多个项目中。 集合视图数据源和委托如下：
func numberOfSections(in collectionView: UICollectionView) -> Int {
return (self.moviemodel?.data.count)!
}
func collectionView(_ collectionView: UICollectionView,numberOfItemsInSection section: Int) -> Int {
switch section {
case 0:
return (self.moviemodel?.data[section].movieList.count)!
default:
return (self.moviemodel?.data[section].movieList.count)!
}
}
func collectionView(_ collectionView: UICollectionView,cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = alllistcollview.dequeueReusableCell(withReuseIdentifier: "Cell",for: indexPath) as! MovielistCell
return cell
}
现在，有一个搜索文本字段，它将搜索任何关键字并过滤要在 collectionview 中显示的结果。
搜索按钮功能如下：
var filteredShopsA = searchDataModel?.data.filter({ item in
print("item is ",item)
$0.matchAddress(keyword)
return false
})
moviemodel?.data = filteredShopsA!
self.alllistcollview.reloadData()
扩展电影列表{
func matchAddress(_ string: String?) -> Bool {
guard let string = string else { return true }
guard let name = name else { return true }
guard let desc = movieListDescription else { return true }
guard let year = releaseYear else { return true }
// guard let rating = ratings else { return true }
return (name.contains(string) || desc.contains(string) || year.contains(string))
}
}
过滤器功能是我没有得到正确的逻辑来展示集合视图上的值。如何根据集合视图的多个部分中的任何文本进行搜索？
