Swift NSViewController背景颜色(Mac App)

class ViewController: NSViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.wantsLayer = true

    }

    override var representedObject: AnyObject? {
        didSet {
        // update the view,if already loaded.
        }
    }

    override func awakeFromNib() {
        if self.view.layer != nil {
            let color : CGColorRef = CGColorCreateGenericRGB(1.0,1.0)
            self.view.layer?.BACkgroundColor = color
        }

    }
}

它将以红色背景初始化视图控制器.

对于标题栏颜色,我创建了NSWindowController并将其从故事板中分配给主窗口控制器.这是代码.

class MainWindow: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

        super.window?.BACkgroundColor = NSColor(calibratedRed: 0.0,green: 1.0,blue: 0.0,alpha: 1.0)
    }

}

我希望这将有所帮助.
