Swift 调整窗口大小时自定义视图已断开（Cocoa）

我在自定义视图中遇到了这个奇怪的错误。自定义视图应该显示分级分布的米数。它被添加到大纲视图的单元视图中

当我调整窗口的大小时，自定义视图不知何故会被压扁，看起来被破坏了。我已经粘贴了下面自定义视图的

drawRect

解决问题的另一种方法是使用NSView。可以使用圆角的容器视图，然后在该容器中绘制子视图（红色、橙色、绿色）。像这样,

我已经为它编写了一个类，您可以根据自己的要求进行定制

public class CProgressView:NSView {

    private lazy var goodView:NSView = {
        let viw:NSView = NSView(frame: NSRect.zero);
        viw.layer = CALayer();
        viw.layer?.backgroundColor = NSColor.greenColor().CGColor;
        self.addSubview(viw)
        return viw;
    } ();

    private lazy var okView:NSView = {
        let viw:NSView = NSView(frame: NSRect.zero);
        viw.layer = CALayer();
        viw.layer?.backgroundColor = NSColor.orangeColor().CGColor;
        self.addSubview(viw)
        return viw;
    } ();

    private lazy var badView:NSView = {
        let viw:NSView = NSView(frame: NSRect.zero);
        viw.layer = CALayer();
        viw.layer?.backgroundColor = NSColor.redColor().CGColor;
        self.addSubview(viw)
        return viw;
    } ();

    private var _goodProgress:CGFloat = 33;
    private var _okProgress:CGFloat = 33;
    private var _badProgress:CGFloat = 34;

    private var goodViewFrame:NSRect {
        get {
            let rect:NSRect = NSRect(x: 0, y: 0, width: (self.frame.size.width * (_goodProgress / 100.0)), height: self.frame.size.height);
            return rect;
        }
    }

    private var okViewFrame:NSRect {
        get {
            let rect:NSRect = NSRect(x: self.goodViewFrame.size.width, y: 0, width: (self.frame.size.width * (_okProgress / 100.0)), height: self.frame.size.height);
            return rect;
        }
    }


    private var badViewFrame:NSRect {
        get {
            let width:CGFloat = (self.frame.size.width * (_badProgress / 100.0));
            let rect:NSRect = NSRect(x: self.frame.size.width - width, y: 0, width: width, height: self.frame.size.height);
            return rect;
        }
    }

    override public init(frame frameRect: NSRect) {
        super.init(frame: frameRect);
        //--
        self.commonInit();
    }

    required public init?(coder: NSCoder) {
        super.init(coder: coder);
    }

    override public func awakeFromNib() {
        super.awakeFromNib();
        //--
        self.commonInit();
    }

    private func commonInit() {
        self.layer = CALayer();
        self.layer!.cornerRadius = 15;
        self.layer!.masksToBounds = true
        //-
        self.updateFrames();
    }

    public func updateProgress(goodProgressV:Int, okProgressV:Int, badProgressV:Int) {
        guard ((goodProgressV + okProgressV + badProgressV) == 100) else {
            NSLog("Total should be 100%");
            return;
        }

        _goodProgress = CGFloat(goodProgressV);
        _okProgress = CGFloat(okProgressV);
        _badProgress = CGFloat(badProgressV);
        //--
        self.updateFrames();
    }

    private func updateFrames() {
        self.layer?.backgroundColor = NSColor.grayColor().CGColor;

        self.goodView.frame = self.goodViewFrame;
        self.okView.frame = self.okViewFrame;
        self.badView.frame = self.badViewFrame;
    }

    public override func resizeSubviewsWithOldSize(oldSize: NSSize) {
        super.resizeSubviewsWithOldSize(oldSize);
        //--
        self.updateFrames();
    }

}

注意：调用updateProgress（）方法更改进度默认值为33、33和34（33+33+34=100）

它对我们重要吗？你不能用VIEW吗？我想保留圆角。BezierPath对我们重要吗？你不能用VIEW吗？我想保持圆角。。
