Instead of overriding any of the init methods you can simply override the windowNibName
property and return a hardcoded string. This allows you to call the basic vanilla init method to create the window controller.
class WindowController: NSWindowController {
override var windowNibName: String! {
return "NameOfNib"
}
}
let windowController = WindowController()
I prefer this over calling let windowController = WindowController(windowNibName: "NameOfNib")
as the name of the nib is an implementation detail that should be fully encapsulated within the window controller class and never exposed outside (and it’s just plain easier to call WindowController()
).
If you want to add additional parameters to the init method do the following:
- In your custom init method call
super.init(window: nil)
. This will getNSWindowController
to init with thewindowNibName
property. - Override the required
init(coder: NSCoder)
method to either configure your object or simply callfatalError()
to prohibit its use (albiet at runtime).
class WindowController: NSWindowController {
var test: Bool
override var windowNibName: String! {
return "NameOfNib"
}
init(test: Bool) {
self.test = test
super.init(window: nil) // Call this to get NSWindowController to init with the windowNibName property
}
// Override this as required per the class spec
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented. Use init()")
// OR
self.test = false
super.init(coder: coder)
}
}
let windowController = WindowController(test: true)
