swift - 如何通过 UISearchBar 文本过滤掉内容？

Question

我用这个代码搜索

extension PlacesVC : UISearchBarDelegate {

    func  searchBarSearchButtonClicked(_ searchBar: UISearchBar) {

        places = places.filter("name CONTAINS[cd] %@", searchBar.text)
        table.reloadData()
    }

    func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
        if searchBar.text?.count == 0 {

            DispatchQueue.main.async {
                searchBar.resignFirstResponder()
            }

        }
    }
}

我不断得到

通话中的额外参数

有谁知道我错过了什么以及如何阻止它？

var places = [["lat": "40.718081110553925", "name": "59 Leonard St", "lon": "-74.00565161821724"], ["lat": "40.87124295389947", "name": "66 Lawrence Ave", "lon": "-74.0764477654279"], ["lat": "40.82326949018643", "name": "685 Fairview Ave", "lon": "-74.00056756991113"]]

你有一个Array. 您正在尝试使用filter但您的论点或更适合NSPredicate. 正确使用filter。

places = places.filter { ($0["name"] ?? "").range(of: searchBar.text, options: [ .caseInsensitive, .diacriticInsensitive ]) != nil }
