swift2 – 在Swift中过滤字典数组

概述我有一个带字典的数组示例： ( { Email = "kate-bell@mac.com"; Name = "Kate Bell"; Number = "(555) 564-8583"; }, { Email = "d-higgins@mac.com"; Name = "Dani 我有一个带字典的数组示例：

(        {        Email = "kate-bell@mac.com";        name = "Kate Bell";        Number = "(555) 564-8583";    },{        Email = "d-higgins@mac.com";        name = "DanIEl Higgins";        Number = "555-478-7672";    })

我想根据密钥“名称”过滤这个字典

func searchbar(searchbar: UISearchbar,textDIDChange searchText: String) {    let predicate = nspredicate(format:"name == %@",searchText)    let filteredArray = (arrContact as NSMutableArray).filteredArrayUsingPredicate(predicate)    print(filteredArray)    if(filteredArray.count == 0){                searchActive = false;            } else {                searchActive = true;            }            tblData.reloadData() }

我总是从上面的swift代码得到空数组.请帮我解决这个问题.谢谢

解决方法 试试这个swift 3

func searchbar(_ searchbar: UISearchbar,textDIDChange searchText: String) {    // Put your key in predicate that is "name"    let searchPredicate = nspredicate(format: "name CONTAINS[C] %@",searchText)    let array = (arrContact as NSArray).filtered(using: searchPredicate)    print ("array = \(array)")    if(array.count == 0){        searchActive = false;    } else {        searchActive = true;    }    self.atable.reloadData()}
