NSSearchField TextDidChange的方法是什么？

Question

macOS中的功能searchBar(_ searchBar: UISearchBar, textDidChange searchText: String)的类似方法是什么？

得到答案：

 @IBOutlet weak var searchBar: NSSearchField!
  func controlTextDidChange(_ obj: Notification){
    let searchObject:NSSearchField? = obj.object as? NSSearchField
    if searchObject==self.searchBar{

    }
}

Answer 1

等效的是委托方法controlTextDidChange:

notification的对象是NSSearchfield。您必须转换类型

@IBOutlet weak var searchBar: NSSearchField!

func controlTextDidChange(_ notification : Notification){
    guard let field = notification.object as? NSSearchField, field == self.searchBar else { return }

}

Answer 2

您需要添加如下图所示的controlTextDidChange方法（最后一个方法），然后添加searchFieldDidEndSearching

跟踪您何时完成搜索或搜索栏是否为空，并且在您清空后才开始编辑文本字段时会调用searchFieldDidStartSearching(_ sender: NSSearchField)

        DispatchQueue.main.async {
            self.searchTable.reloadData()
        }
    }

    func searchFieldDidStartSearching(_ sender: NSSearchField) {


    }

    func controlTextDidChange(_ obj: Notification) {
        guard let field = obj.object as? NSSearchField, field == self.searchBar else { return }
        filteredPokemonList = allPokemonList.filter({ (pokemon) -> Bool in
            return pokemon.name.lowercased().contains(field.stringValue.lowercased())
        })

        DispatchQueue.main.async {
            self.searchTable.reloadData()
        }
    }
