Rounded corners of MKMapView

I'm building a custom UITableView with each of the cells containing a piece of text and a MKMapView. I want the map "icon" view in the cell to have rounded corners and this seems to be an issue. I'm using custom drawing both for my UITableViewCell and my `MapIcon` (custom map view) that I add to my UITableViewCell. `MapIcon` is a subclass of `MKMapView` and the drawing method looks as follows: -(void)drawRect:(CGRect)rect { ``` CGContextRef context = UIGraphicsGetCurrentContext(); CGContextSetLineWidth(context, strokeWidth); CGContextSetStrokeColorWithColor(context,self.strokeColor.CGColor); CGContextSetFillColorWithColor(context, self.rectColor.CGColor); CGFloat radius = arcRadius; CGFloat Xmin = CGRectGetMinX(rect); CGFloat Xmid = CGRectGetMidX(rect); CGFloat Xmax = CGRectGetMaxX(rect); CGFloat Ymin = CGRectGetMinY(rect); CGFloat Ymid = CGRectGetMidY(rect); CGFloat Ymax = CGRectGetMaxY(rect); ``` CGContextBeginPath(context); CGContextMoveToPoint(context, Xmin, Ymid); CGContextAddArcToPoint(context, Xmin, Ymin, Xmid, Ymin, radius); CGContextAddArcToPoint(context, Xmax, Ymin, Xmax, Ymid, radius); CGContextAddArcToPoint(context, Xmax, Ymax, Xmid, Ymax, radius); CGContextAddArcToPoint(context, Xmin, Ymax, Xmin, Ymid, radius); CGContextClosePath(context); ``` CGContextDrawPath(context, kCGPathFillStroke); ``` CGContextClip(context); CGContextEndTransparencyLayer(context); } And the maps do not get the corners rouned, as can be seen in the below screenshot: alt text http://img190.imageshack.us/img190/948/picture1vmk.png If however I change the `MapIcon` to subclass from UIView and use the same custom drawing methods, the view gets clipped perfectly, image below: alt text http://img503.imageshack.us/img503/6269/picture2xkq.png Is it wrong for me to subclass MKMapView in such a way and expect it to clip? Any other any of rounding these corners? Cheers, Kaspa
