Changing the Button Title for Open and Save Panels

Open and save panels are how Mac apps let people open and save files. An open panel defaults to using Open as the text for the main button. A save panel defaults to using Save. The default values make sense, but suppose you want to use an open panel to import a file in your app. How do you change the button text from Open to Import?

Use the prompt property to change the button text. The following example shows how to change the button text in an open panel from Open to Import:

func buildImportOpenPanel() -> NSOpenPanel {
  let openPanel = NSOpenPanel()
  openPanel.prompt = "Import"
  return openPanel
}

Look at the NSSavePanel class reference to see other ways to customize the appearance of save and open panels.
