我的NSWindowController类中有一个NSToolBar按钮的IBOutlet,这是我的主窗口类：
class MainWindowController: NSWindowController {
@IBOutlet weak var myButton: NSButton!
// ...
}
我有一个类MainViewController,它是主窗口的内容NSViewController.
如何在我的内容NSViewController中访问此按钮？有没有更好的方法来组织IBOutlets和控制器来促进这种访问？
这样使用委托怎么样？此示例将更改按钮的标题.

func changeTitle(title: String)
}
class ViewController: NSViewController {
weak var delegate: SomeDelegate?
@IBAction func myAction(sender: AnyObject) {
delegate?.changeTitle("NewTitle")
}
}
class MainWindowController: NSWindowController,SomeDelegate {
@IBOutlet weak var myButton: NSButton!
override func windowDidLoad() {
super.windowDidLoad()
// Implement this method to handle any initialization after your window controller's window has been loaded from its nib file.
let myVc = window!.contentViewController as! ViewController
myVc.delegate = self
}
func changeTitle(title: String) {
myButton.title = title
}
}
