swift - NSSearchField TextDidChange 的方法是什么？

Question

macOS 中函数 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

等价的是委托(delegate)方法 controlTextDidChange:

通知的对象是NSSearchfield。您必须强制转换类型

@IBOutlet weak var searchBar: NSSearchField!

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

}
