NSOpenPanel讲解

首先把2个按钮连线到swift文件中,2个按钮代码如下:
NSOpenPanel 创建对象以后通过 设置属性canChooseDirectories和canChooseFiles实现打开文件或者文件夹
通过block beginSheetModal实现打开文件窗口.

代码例子

  var pathUrls = [URL]()//保存选择所有文件的路径数组//MARK: - 选择文件@IBAction func btnOpenFileClick(_ sender: Any) {let openPanel = NSOpenPanel()openPanel.prompt = "选择"openPanel.canChooseDirectories = false //不允许选择目录openPanel.canChooseFiles = true //选择文件openPanel.allowsMultipleSelection = true//允许多选openPanel.beginSheetModal(for: view.window!) {[unowned self]  result inif result != .OK { //result是点击的结果,如果点击确定result == .OKprint("点击取消")return}//遍历多选的所有路径for url in openPanel.urls{print("路径是=",url.path)}pathUrls = openPanel.urls}}//MARK: - 选择目录@IBAction func btnOpenDirClick(_ sender: Any) {let openPanel = NSOpenPanel()openPanel.prompt = "选择"openPanel.canChooseDirectories = true //openPanel.allowsMultipleSelection = trueopenPanel.canChooseFiles = falseopenPanel.beginSheetModal(for: view.window!) { [unowned self]  result inif result != .OK {print("点击取消")return}//遍历多选的所有路径for url in openPanel.urls{print("路径是=",url.path)}pathUrls = openPanel.urls}}//MARK: - 用finder打开文件所在位置@IBAction func btnOpenPathClick(_ sender: Any) {print("pathUrls=",pathUrls)NSWorkspace.shared.activateFileViewerSelecting(pathUrls)}
