Setting value for title of NSOpenPanel does not work-CodePudding

I want to set title for my NSOpenPanel, but it does not work! Apple says:

Gets and sets the title for the panel shown at the top of the window.

But I can not make codes works, not sure what is wrong?

let nsOpenPanel = NSOpenPanel()
    nsOpenPanel.canChooseFiles = true
    nsOpenPanel.title = "Hello, Choose Files"

   if (nsOpenPanel.runModal() == .OK) ... // rest of codes ...

CodePudding user response：

The title is something from the past when windows in macOS had title bars. To show text or an instruction on top of the NSOpenPanel object, use the message property:

nsOpenPanel.message = "Hello, Choose Files"
