macOS store sandbox应用程序使用NSOpenPanel选择下载文件文件夹，但无法再次访问该文件夹
我的应用程序是从网站下载文件 我为macOS商店启用了项目的沙箱 应用程序将触发NSOpenPanel，要求用户选择下载文件（所有文件列表存储在sqlite文件中）保存到的文件夹。 例如：macOS store sandbox应用程序使用NSOpenPanel选择下载文件文件夹，但无法再次访问该文件夹,macos,cocoa,sandbox,Macos,Cocoa,Sandbox,我的应用程序是从网站下载文件 我为macOS商店启用了项目的沙箱 应用程序将触发NSOpenPanel，要求用户选择下载文件（所有文件列表存储在sqlite文件中）保存到的文件夹。 例如： /home/mymac/myfolder 一切都好。如果我关闭应用程序并重新打开它，我希望它可以继续下载文件（在sqlite文件中） 但它报告了错误： 设置安全信息：不允许操作 系统似乎不允许应用程序访问该文件夹 /home/mymac/myfolder /home/mymac/Downloads 再

用法：
fileprivate func initialize() // Put a call to this in func applicationDidFinishLaunching(_ aNotification: Notification)
{
let directories = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
let path = directories[0].appending("/SecureBookmarks.dict")
SecureFolders.initialize(path)
SecureFolders.load()
}
要将文件夹添加到安全书签，请执行以下操作：
fileprivate func allow(_ path: String)
{
SecureFolders.allow(folder: path, prompt: "Open")
{
result in
// Update controls or whatever
}
}
不要忘记设置显示NSOpenPanel
所需的窗口实例。您可以在其中一个NSViewController的视图显示中设置实例：
override func viewDidAppear()
{
super.viewDidAppear()
SecureFolders.window = NSApplication.shared.mainWindow
}
您需要获取URL的书签并将其永久存储。当应用程序打开时，从存储的书签中检索URL
操作方法在文档中有描述：
您只需要两种方法：
- (NSData*)bookmarkForURL:(NSURL*)url
- (NSURL*)urlForBookmark:(NSData*)bookmark
您可以将书签存储在.plist
文件中，如果您不希望有大量书签，甚至可以存储在UserDefaults中。您需要获取URL的书签并将其永久存储。当应用程序打开时，从存储的书签中检索URL
