    <p>Hope you can convert <code>CLLocationCoordinate2D</code> to <code>CGPoint</code> by the following way, then you may have the coordinates of all points.</p> <pre><code>//CGPoint myPoint = CGPointMake(coordinate.longitude, coordinate.latitude); CGPoint Point = [self.mapView convertCoordinate:self.mapCoordinate toPointToView:self.mapView]; </code></pre> <p>Then you can try the way as per the link</p> <p><a href="http://www.wikihow.com/Sample/Area-of-an-Irregular-Polygon" rel="nofollow">http://www.wikihow.com/Sample/Area-of-an-Irregular-Polygon</a></p> <pre><code>CLLocationCoordinate2D overflowLotCoords[15]={ CLLocationCoordinate2DMake(39.04864351611461,-76.8513227245313), CLLocationCoordinate2DMake(39.04851710015167,-76.8517540587399), CLLocationCoordinate2DMake(39.04868674731313,-76.85192728689483), CLLocationCoordinate2DMake(39.04850095882104,-76.85230365946416), CLLocationCoordinate2DMake(39.04819087100218,-76.85265260435219), CLLocationCoordinate2DMake(39.0477370134458,-76.85286078490296), CLLocationCoordinate2DMake(39.04692851484644,-76.85283202926037), CLLocationCoordinate2DMake(39.04695987529381,-76.85235192135768), CLLocationCoordinate2DMake(39.04734847050665,-76.85236298239703), CLLocationCoordinate2DMake(39.04779491740192,-76.85232236959109), CLLocationCoordinate2DMake(39.04814366462639,-76.85208905182692), CLLocationCoordinate2DMake(39.04838024069194,-76.85164072166863), CLLocationCoordinate2DMake(39.04843331131504,-76.85085998781742), CLLocationCoordinate2DMake(39.04857547181026,-76.8507923535788), CLLocationCoordinate2DMake(39.04864351611461,-76.8513227245313) }; NSMutableArray *marrPointsList = [NSMutableArray array]; for (int i = 0; i &lt; 15; i++) { CLLocationCoordinate2D coordinate = overflowLotCoords[i]; CGPoint point = [self.myMapView convertCoordinate:overflowLotCoords[i] toPointToView:self.myMapView]; NSLog(@"convert %@", NSStringFromCGPoint(point)); [marrPointsList addObject:[NSValue valueWithCGPoint:point]]; } </code></pre> <p>hope this code snippet may help you.</p>

    1. COI am using the below method to convert the coordinate to CGPoint, but I am unable to get exact cartesian point. CGPoint Point = [self.mapView convertCoordinate:self.mapCoordinate toPointToView:self.mapView]; Thanks!!

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.
