Swift + NSViewController background color (Mac App)

Question

I am trying to change the background color of my View. The View Controller class is NSViewController type.

How this can be done? In iOS UIKit (UIViewController) there is self.view.backgroundColor, but NSViewController doesn't have that.

And second problem is how can I change the color of the applications Title Bar? I think the background color doesn't affect to that.

Mac application, language Swift. XCode 6.1.

Answer 1

I managed to change background color of main view. NSViewController does not have backgroundColor property indeed, so I used the layer property of NSView that belongs to NSViewController. Here is the code.

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, 0, 0, 1.0)
            self.view.layer?.backgroundColor = color
        }

    }
}

It will initialize the view controller with red background.

For Title Bar color, I created NSWindowController and assinged it to main window controller from storyboard. Here is the code.

class MainWindow: NSWindowController {

    override func windowDidLoad() {
        super.windowDidLoad()

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

}

I hope this will help.
