表单使用 AppleScriptObjC 有点麻烦，但 Myriad Helpers 有很大帮助。 要使用 NSOpenSave+MyriadHelpers 类别，请使用 File > Add Files to …[=16 将它们的 .h 和 .m 文件添加到您的 Xcode 项目中=] 菜单项。例如，从一个新的（默认）AppleScript 应用程序项目，您可以执行以下操作：

on applicationDidFinishLaunching_(aNotification)
    tell current application's NSOpenPanel's openPanel()
        its setMessage:"Please select a file:"
        its setPrompt:"Choose"
        its setDirectoryURL:(current application's NSURL's fileURLWithPath:(POSIX path of (path to desktop)))

        its setCanChooseFiles:true
        its setCanChooseDirectories:false
        its setAllowsMultipleSelection:true
        its setAllowedFileTypes:{"png"} -- list of extensions or UTIs

        its showOver:theWindow calling:{"panelCompletion:", me}
    end tell
end

on panelCompletion:openItems
    if openItems is missing value then -- "Cancel" button
        log "Cancel"
        return -- or whatever
    end if
    repeat with anItem in openItems as list
        log anItem -- do your thing with the individual file paths
    end repeat
end panelCompletion:
