MacOS APP 设置窗口大小不可调整

    override func viewDidAppear() {
        super.viewDidAppear()
        self.view.window?.styleMask.remove(.resizable)
    }

1、移除resizable类型
2、放在viewDidAppear中

我尝试过放在viewDidLoad总，无效！
一个比较有意思的事情是：NSWindow.StyleMask的类型是OptionSet

public struct StyleMask : OptionSet {

        public init(rawValue: UInt)

        
        public static var borderless: NSWindow.StyleMask { get }

        public static var titled: NSWindow.StyleMask { get }

        public static var closable: NSWindow.StyleMask { get }

        public static var miniaturizable: NSWindow.StyleMask { get }

        public static var resizable: NSWindow.StyleMask { get }

        
        @available(OSX, introduced: 10.2, deprecated: 100000, message: "Textured window style should no longer be used")
        public static var texturedBackground: NSWindow.StyleMask { get }

        
        public static var unifiedTitleAndToolbar: NSWindow.StyleMask { get }

        
        @available(OSX 10.7, *)
        public static var fullScreen: NSWindow.StyleMask { get }

        
        @available(OSX 10.10, *)
        public static var fullSizeContentView: NSWindow.StyleMask { get }

        
        public static var utilityWindow: NSWindow.StyleMask { get }

        public static var docModalWindow: NSWindow.StyleMask { get }

        public static var nonactivatingPanel: NSWindow.StyleMask { get }

        @available(OSX 10.6, *)
        public static var hudWindow: NSWindow.StyleMask { get }
    }
