NSOpenPanel作为工作表

问题描述

我环顾了其他答案，但似乎没有任何帮助.

Ive looked around at other answers, but nothing seems to be helping my case.

我有一个viewController类，其中包含按钮的IBAction.此按钮应从该viewController的表单中打开一个NSOpenPanel:

I have a viewController class which contains an IBAction for a button. This button should open a NSOpenPanel as a sheet from that viewController:

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myFileDialog.beginSheetModalForWindow(..)，它与上面的行一起使用，但这不是工作表效果

The problem comes from myFileDialog.beginSheetModalForWindow(..) , it works with the line above, but that is not a sheet effect

推荐答案

您需要在窗口的面板上调用beginSheetModalForWindow，并使用完成块:

You need to call beginSheetModalForWindow from your panel on your window, and use a completion block:

let myFiledialog = NSOpenPanel()
myFiledialog.prompt = "Select path"
myFiledialog.worksWhenModal = true
myFiledialog.allowsMultipleSelection = false
myFiledialog.canChooseDirectories = true
myFiledialog.canChooseFiles = false
myFiledialog.resolvesAliases = true
myFiledialog.beginSheetModalForWindow(window, completionHandler: { num in
    if num == NSModalResponseOK {
        let path = myFiledialog.URL
        print(path)
    } else {
        print("nothing chosen")
    }
})
