NSImageView rounded corners + stroke

I have subclasses NSImageView and i want to draw a border around with rounded corners. It works but i need to clip off the image corners as well.

Please see my screenshot:

I have created this code to draw the border/corners.

- (void)drawRect:(NSRect)dirtyRect
{
    [super drawRect:dirtyRect];

    NSColor *strokeColor;
    if(self.isSelected)
        strokeColor = [NSColor colorFromHexRGB:@"f9eca2"];
    else
        strokeColor = [NSColor colorFromHexRGB:@"000000"];

    [strokeColor set];    
    [[NSBezierPath bezierPathWithRoundedRect:NSInsetRect(dirtyRect, 1, 1) xRadius:5 yRadius:5] stroke];
}

What should i do to make the image clip ?

EDIT:

Well i fixed it, but i feel its an ugly way to do it. Anything smarter?

NEW CODE:

- (void)drawRect:(NSRect)dirtyRect
{
    NSBezierPath *path = [NSBezierPath bezierPathWithRoundedRect:NSInsetRect(dirtyRect, 2, 2) xRadius:5 yRadius:5];

    [path setLineWidth:4.0];
    [path addClip];

    [self.image drawAtPoint: NSZeroPoint
                 fromRect:dirtyRect
                 operation:NSCompositeSourceOver
                 fraction: 1.0];

    [super drawRect:dirtyRect];

    NSColor *strokeColor;
    if(self.isSelected)
    {
        strokeColor = [NSColor colorFromHexRGB:@"f9eca2"];
    }
    else
        strokeColor = [NSColor colorFromHexRGB:@"000000"];

    [strokeColor set];    
    [NSBezierPath setDefaultLineWidth:4.0];
    [[NSBezierPath bezierPathWithRoundedRect:NSInsetRect(dirtyRect, 2, 2) xRadius:5 yRadius:5] stroke];
}

Set the corner radius of your NSImageViews layer also to 5 px and set its maskToBounds property to YES.
