我知道如何将AccessoryView添加到NSOpenPanel(并且可以正常工作)。
现在,我想使用户在AccessoryView中选择的选项可用于打开的文档。
任何建议都可以做到(如果有的话)
答案 0 :(得分:0)
我还没有找到标准的解决方案,所以我创建了自己的解决方案:
这个解决方案并没有让我震惊,但是我也看不到更简单的方法。
示例代码:
struct OptionsAtFileOpen {
let alsoLoadFormat: Bool
}
class DocumentController: NSDocumentController {
var fileOptions: Dictionary<URL, OptionsAtFileOpen> = [:]
var accessoryViewController: OpenPanelAccessoryViewController!
override func runModalOpenPanel(_ openPanel: NSOpenPanel, forTypes types: [String]?) -> Int {
// Load accessory view
let accessoryViewController = OpenPanelAccessoryViewController(nibName: NSNib.Name(rawValue: "OpenPanelAccessoryView"), bundle: nil)
// Add accessory view and make sure it is shown
openPanel.accessoryView = accessoryViewController.view
openPanel.isAccessoryViewDisclosed = true
// Run the dialog
let result = super.runModalOpenPanel(openPanel, forTypes: types)
// If not cancelled, add the files to open to the fileOptions dictionary
if result == 1 {
// Return the state of the checkbox that selects the loading of the formatting file
let alsoLoadFormat = accessoryViewController.alsoLoadFormatFile.state == NSControl.StateValue.on
for url in openPanel.urls {
fileOptions[url] = OptionsAtFileOpen(alsoLoadFormat: alsoLoadFormat)
}
}
return result
}
}
然后在文档中
override func read(from data: Data, ofType typeName: String) throws {
...
if let fileUrl = fileURL {
if let dc = (NSDocumentController.shared as? DocumentController) {
if let loadFormat = dc.fileOptions[fileUrl]?.alsoLoadFormat {
...
}
}
}
}
