MAC OS Xcode Swift 2.2 Fullscreen Mode

问题

What Swift code will switch the app to fullscreen? I found references with example code for IOS. I am looking for a code which works for a MacOS app.

One way is to override viewDidAppear in NSViewController:

class ViewController : NSViewController {

    override func viewDidAppear() {
        let presOptions: NSApplicationPresentationOptions = ([.FullScreen,.AutoHideMenuBar])   
        let optionsDictionary = [NSFullScreenModeApplicationPresentationOptions :
            NSNumber(unsignedLong: presOptions.rawValue)]
        self.view.enterFullScreenMode(NSScreen.mainScreen()!, withOptions:optionsDictionary)
        self.view.wantsLayer = true
        }
}

↳ Apple Developer API Reference : viewDidAppear()

Updated for Swift 4

override func viewDidAppear() {
    let presOptions: NSApplication.PresentationOptions = [.fullScreen, .autoHideMenuBar]
    let optionsDictionary = [NSView.FullScreenModeOptionKey.fullScreenModeApplicationPresentationOptions: presOptions]
    view.enterFullScreenMode(NSScreen.main!, withOptions: optionsDictionary)
    view.wantsLayer = true
}

An alternative, if you want different behavior, where the menu bar is available when you move your mouse to top is this. However, it starts out as a normal size window then grows, so that may not be desirable depending on what you are doing.

override func viewDidAppear() {
    view.window?.toggleFullScreen(self)
}
