ios - 搜索过滤器必须从[[String:Any]]()数组过滤到新的过滤数组？

我有一个tableview，我在其中从命名为PlaylistArray的数组中加载所有详细信息。我有一个搜索页面，用户可以在其中搜索playlistArray类型的[[String: Any]]。我不知道如何将用户在PlayListArray中给出的搜索文本过滤为filteredArray。我已附上PlaylistArray答复供您参考。

这是我之前尝试过滤PlaylistArray的代码。

 let searchPredicate = NSPredicate(format: "SELF CONTAINS[c] %@", searchController.searchBar.text!)
 let array = (constantsList.playTypeArray.lectureArraymp3 as NSArray).filtered(using: searchPredicate)
          //  filtered_Array.add(array)
 print(array)

我需要搜索用户提供的搜索文本，我们必须将搜索文本与title的playlistArray标记进行比较。当两者相同时，我需要向过滤后的数组显示特定数组索引的全部详细信息。

PlaylistArray：

[["title": Kaṭha-Bhāṣyam-41 Mantra 1-2-20, "image_url": https://www.imaginetventures.name/swamijione/wp-content/uploads/2019/01/gitanew.png, "mp3": https://www.imaginetventures.name/swamiji/wp-content/uploads/2018/12/01-PURU],["title": Kaṭha-Bhāṣyam-41 Mantra 1-2-20, "image_url": https://www.imaginetventures.name/swamijione/wp-content/uploads/2019/01/gitanew.png, "mp3": https://www.imaginetventures.name/swamiji/wp-content/uploads/2018/12/01-PURU],["title": Kaṭha-Bhāṣyam-41 Mantra 1-2-20, "image_url": https://www.imaginetventures.name/swamijione/wp-content/uploads/2019/01/gitanew.png, "mp3": https://www.imaginetventures.name/swamiji/wp-content/uploads/2018/12/01-PURU]]

最佳答案

这是使用filter API快速解决方案。在此处了解更多信息：https://developer.apple.com/documentation/swift/sequence/3018365-filter

let array = [["title": "Kaṭha-Bhāṣyam-41 Mantra 1-2-20", "image_url": "https://www.imaginetventures.name/swamijione/wp-content/uploads/2019/01/gitanew.png"],
             ["title": "Kaṭa-Bhāṣyam-41 Mantra 1-2-20", "image_url": "https://www.imaginetventures.name/swamijione/wp-content/uploads/2019/01/gitanew.png"]]

guard let searchText = searchController.searchBar.text else {return} //Or use if-let
let filteredArray = array.filter { (object) -> Bool in
    guard let title = object["title"] as? String else {return false}
    return title?.contains(searchText) ?? false
}
