NSOpenPanel片材

Question

我环顾四周看了看其他的答案，但似乎没有什么对我的案子有帮助。

我有一个viewController类，它包含一个按钮的IBAction。此按钮应将NSOpenPanel作为来自该viewController的工作表打开：

class ViewController: NSViewController {
@IBAction func folderSelection(sender: AnyObject) {
    var myFiledialog: NSOpenPanel = NSOpenPanel()
    myFiledialog.prompt = "Select path"
    myFiledialog.worksWhenModal = true
    myFiledialog.allowsMultipleSelection = false
    myFiledialog.canChooseDirectories = true
    myFiledialog.canChooseFiles = false
    myFiledialog.resolvesAliases = true

    //myFiledialog.runModal()

    myFiledialog.beginSheetModalForWindow(self.view.window!, completionHandler: nil)


    var chosenpath = myFiledialog.URL
    if (chosenpath!= nil)
    {
        var TheFile = chosenpath!.absoluteString!
        println(TheFile)
        //do something with TheFile
    }
    else
    {
        println("nothing chosen")
    }
}
}

问题来自于myFileDialog.beginSheetModalForWindow(..)，它适用于上面的一行，但这不是工作表效果

Swift 5

let dialog = NSOpenPanel()
dialog.beginSheetModal(for: self.view.window!){ result in
    if result == .OK, let url = dialog.url {
        print("Got", url)
    }
}
