我看了看其他答案,但似乎没有任何帮助我的情况.
我有一个viewController类,它包含一个按钮的IBAction.此按钮应该从该viewController打开NSOpenPanel作为工作表：
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(..),它适用于上面的行,但这不是一个工作表效果
您需要从窗口的面板调用beginSheetModalForWindow,并使用完成块：
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")
}
})
