Objective c NSPopUpButtonCell子类以标准外观设置关闭动画

我创建了一个NSPopUpButtonCell子类来定制它的外观

当从弹出窗口中选择一个菜单项时，它将以OS X 10.10上的标准弹出窗口外观为选择设置动画

我希望它与我的自定义外观动画

自定义弹出窗口

设置所选内容的动画

- (void)drawBezelWithFrame:(NSRect)frame inView:(NSView *)controlView {

    [[NSGraphicsContext currentContext] saveGraphicsState];

    NSBezierPath *rectanglePath = [NSBezierPath bezierPathWithRoundedRect:frame xRadius:5.0 yRadius:5.0];
    [[NSColor colorWithWhite:0.7 alpha:1.0] setFill];
    [rectanglePath fill];

    float width = frame.size.width;
    float height = frame.size.height;

    NSBezierPath *path = [NSBezierPath bezierPath];

    [path moveToPoint:CGPointMake(width - 5, height/2 - 2)];
    [path lineToPoint:CGPointMake(width - 10, height/2 - 7)];
    [path lineToPoint:CGPointMake(width - 15, height/2 - 2)];


    [path moveToPoint:CGPointMake(width - 5, height/2 + 2)];
    [path lineToPoint:CGPointMake(width - 10, height/2 + 7)];
    [path lineToPoint:CGPointMake(width - 15, height/2 + 2)];

    [path setLineWidth:2.0];

    [[NSColor darkGrayColor] setStroke];
    [path stroke];

    [NSGraphicsContext restoreGraphicsState];
}

- (void)drawBezelWithFrame:(NSRect)frame inView:(NSView *)controlView {

    [[NSGraphicsContext currentContext] saveGraphicsState];

    NSBezierPath *rectanglePath = [NSBezierPath bezierPathWithRoundedRect:frame xRadius:5.0 yRadius:5.0];

    [path setLineWidth:2.0];

    [[NSColor darkGrayColor] setStroke];
    [path stroke];

    [NSGraphicsContext restoreGraphicsState];
}

必须在界面生成器上关闭“边界”属性

如果“边界”实际上处于关闭状态，则必须打开它，然后再关闭它

更好的方法是使用 -（void）DrawBorderAndBackgroundithFrame:（NSRect）查看中的单元格框架：（NSView*）控制视图
