首先,我是Swift的新手,如果我的问题看起来微不足道,我感到抱歉。

我想要一个非常简单的命令行程序,该程序可以打开一个对话框来选择文件或文件夹。此工具不得在Dock中运行带有图标弹跳的实际完整应用,而应包含一些细微的内容。而已。我所做的工作正好能产生这种效果,只是小组无法获得关注。当我单击面板时,它保持灰色。有趣的是,可以单击按钮或拖放文件,但是无法浏览文件系统。键盘事件也不会被捕获。

import AppKit

let dialog = NSOpenPanel()

dialog.title                   = "Choose a .tif file or a folder";
dialog.showsResizeIndicator    = true;
dialog.showsHiddenFiles        = false;
dialog.canChooseDirectories    = true;
dialog.canCreateDirectories    = true;
dialog.allowsMultipleSelection = false;
dialog.allowedFileTypes        = ["tif", "tiff"];
dialog.isFloatingPanel         = true;

if (dialog.runModal() == NSApplication.ModalResponse.OK)
{
  let result = dialog.url // Pathname of the file
  if (result != nil)
  {
    let path = result!.path
    print(path)
    exit(0)
  }
}

exit(1)

如何显示正常运行的NSOpenPanel?即:可以获取焦点,可以与鼠标和键盘进行交互,...

在这种情况下(无窗口的应用程序),您需要将NSApplication激活策略设置为.accessory来激活面板(还有.regular,但它会显示Dock图标和菜单栏)

import AppKit

NSApplication.shared.setActivationPolicy(.accessory)

let dialog = NSOpenPanel()

dialog.title                   = "Choose a .tif file or a folder"
dialog.showsResizeIndicator    = true
dialog.showsHiddenFiles        = false
dialog.canChooseDirectories    = true
dialog.canCreateDirectories    = true
dialog.allowsMultipleSelection = false
dialog.allowedFileTypes        = ["tif", "tiff"]
dialog.isFloatingPanel         = true


if (dialog.runModal() == NSApplication.ModalResponse.OK)
{
    let result = dialog.url // Pathname of the file
    if (result != nil)
    {
        let path = result!.path
        print(path)
        exit(0)
    }
}

exit(1)
