I have an NSDocument
subclass that has its own xib file. Also I have an NSViewController
subclass with its own xib file too, and I want to present its view modally, like this one.
Problem is, it always shows it as a separate floating window without title bar.
The view I'm trying to present is contained in a window in that xib file. And yes, it's Mac OS X 10.10. Here's the code.
@IBAction func didPressEditF(sender: AnyObject) {
let controller = ViewController(nibName: "ViewController", bundle: nil)
let window = self.windowControllers[0].window as NSWindow
window.beginSheet(controller.view.window, completionHandler: didEndPresentingF)
}
It's OK if you help me using Objective-C.
Alright. I figured it out.
At first. We need a property of our ViewController
class so it won't get released after showing.
var controller: ViewController?
Then we need a method that will return a window of the current document. Somehow self.windowControllers[0].window as NSWindow
doesn't work.
func window() -> NSWindow {
let windowControllers = self.windowControllers
let controller = windowControllers[0] as NSWindowController
let window = controller.window
return window
}
And finally, the code that opens up the sheet window will look like this:
@IBAction func didPressEditF(sender: AnyObject) {
controller = ViewController(nibName: "ViewController", bundle: nil)
self.window().beginSheet(controller!.view.window, completionHandler: didEndPresentingF)
}
Apple HAS to do something with their outdated documentation.
Instead of digging through the document's window controllers, you could call windowForSheet, a method on NSDocument. Eg self.windowForSheet.
