    <p>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.</p> <p>I'm using custom drawing both for my UITableViewCell and my <code>MapIcon</code> (custom map view) that I add to my UITableViewCell.</p> <p><code>MapIcon</code> is a subclass of <code>MKMapView</code> and the drawing method looks as follows:</p> <blockquote> <p>-(void)drawRect:(CGRect)rect {</p> <pre><code>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); </code></pre> <p>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);</p> <pre><code>CGContextDrawPath(context, kCGPathFillStroke); </code></pre> <p>CGContextClip(context); CGContextEndTransparencyLayer(context); }</p> </blockquote> <p>And the maps do not get the corners rouned, as can be seen in the below screenshot:</p> <p><a href="http://img190.imageshack.us/img190/948/picture1vmk.png">alt text http://img190.imageshack.us/img190/948/picture1vmk.png</a></p> <p>If however I change the <code>MapIcon</code> to subclass from UIView and use the same custom drawing methods, the view gets clipped perfectly, image below:</p> <p><a href="http://img503.imageshack.us/img503/6269/picture2xkq.png">alt text http://img503.imageshack.us/img503/6269/picture2xkq.png</a></p> <p>Is it wrong for me to subclass MKMapView in such a way and expect it to clip? Any other any of rounding these corners?</p> <p>Cheers, Kaspa </p>

    1. CODid you find that putting a mapview here crashes when it exits and re-enteres the view?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
