    <p>I had the same problem. There is a serious of blog posts about this topic on this blog <a href="http://spitzkoff.com/craig/?p=81" rel="nofollow noreferrer">http://spitzkoff.com/craig/?p=81</a>.</p> <p>Just using the <code>MKMapViewDelegate</code> doesn't help you here and subclassing <code>MKMapView</code> and trying to extend the existing functionality also didn't work for me.</p> <p>What I ended up doing is to create my own <code>CustomCalloutView</code> that I am having on top of my <code>MKMapView</code>. You can style this view in any way you want.</p> <p>My <code>CustomCalloutView</code> has a method similar to this one:</p> <pre> <code> - (void) openForAnnotation: (id)anAnnotation { self.annotation = anAnnotation; // remove from view [self removeFromSuperview]; titleLabel.text = self.annotation.title; [self updateSubviews]; [self updateSpeechBubble]; [self.mapView addSubview: self]; } </code> </pre> <p>It takes an <code>MKAnnotation</code> object and sets its own title, afterward it calls two other methods which are quite ugly which adjust the width and size of the callout contents and afterward draw the speech bubble around it at the correct position.</p> <p>Finally the view is added as a subview to the mapView. The problem with this solution is that it is hard to keep the callout at the correct position when the map view is scrolled. I am just hiding the callout in the map views delegate method on a region change to solve this problem.</p> <p>It took some time to solve all those problems, but now the callout almost behaves like the official one, but I have it in my own style.</p>

    1. COI second that: UICalloutView is a private class and not available in the SDK officially. Your best bet is to follow Sascha's advice.

    2. COHi Sascha, We thank you for your reply. But, the current problem that we are experiencing is how to get the position (x,y and not lat or long) on the map where the pins appear, so that we can display the callout view.

    3. COconverting coordinates can easily be done by two function of MKMapView: # – convertCoordinate:toPointToView: # – convertPoint:toCoordinateFromView:

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.
