Question

如何将NSApplicationPresentationOptions转换为AnyObject?？ as在这里不起作用。
我想打电话：

func enterFullScreenMode(_ screen: NSScreen, withOptions options: [NSObject: AnyObject]?) -> Bool

我有：

let presOptions: NSApplicationPresentationOptions =
    .HideDock                  |   // Dock is entirely unavailable. Spotlight menu is disabled.
    .AutoHideMenuBar           |   // Menu Bar appears when moused to.
    .DisableAppleMenu          |   // All Apple menu items are disabled.
    .DisableProcessSwitching   |   // Cmd+Tab UI is disabled. All Exposé functionality is also disabled.
    .DisableForceQuit          |   // Cmd+Opt+Esc panel is disabled.
    .DisableSessionTermination |   // PowerKey panel and Restart/Shut Down/Log Out are disabled.
    .DisableHideApplication    |   // Application "Hide" menu item is disabled.
    .AutoHideToolbar           |
    .FullScreen

let optionsDictionary = [NSFullScreenModeApplicationPresentationOptions: presOptions]

browserWindowController.containerView.enterFullScreenMode(NSScreen.mainScreen()!, withOptions: optionsDictionary)

这给了我最后一行的错误：

Cannot invoke 'enterFullScreenMode' with an argument list of type '(NSScreen, with Options: [String : NSApplicationPresentationOptions])'

根据documentation，相应的值为键 NSFullScreenModeApplicationPresentationOptions 是NSNumber的实例，包含无符号整数值NSApplicationPresentationOptions，因此这应该有效：

let optionsDictionary = [NSFullScreenModeApplicationPresentationOptions : 
                         NSNumber(unsignedLong: presOptions.rawValue)]

Swift类型转换
