其实这是swift 2.0中的代码，有人能告诉我如何在swift 3.0中编写这些代码吗？

Question

func searchBar(searchBar: UISearchBar, textDisChange searchText:String){ 
    filteredArray =tableData.filter({ names: String) ->Bool in 
    return name.lowercaseString.rangeOfString(of: searchText.lowercaseString) 
    }) 
} 

Answer 1

试试这个：

func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) 
{ 
    filteredArray = tableData.filter { (names) -> Bool in 
     return (names.lowercased().range(of: searchText.lowercased()) != nil) 
    } 
}
