iPhone MKMapView - MKPolygon Issues

Question

I am trying to plot a MKPolygon on a MKMapView in iOS 4.0. I have an NSArray which contains custom objects that include properties for latitude/longitude. I have a code samp

Answer 1

coordinatesArray; //Your array containing the coordinates

for (int i=0; i <[coordinatesArray count]; i++) 
{
   float latitude  = [coordinatesArray[i][@"latitude"] floatValue];
   float longitude  = [coordinatesArray[i][@"longitude"] floatValue];
   MKPolygon *polygon;
   CLLocationCoordinate2D coordinates[[coordinatesArray count]];
   coordinates[i] = CLLocationCoordinate2DMake(latitude , longitude);
   polygon = [MKPolygon polygonWithCoordinates:coordinates count:[coordinatesArray count]];
   [self.mapView addOverlay:polygon];
}

//Your "coordinatesArray" is an array containing the dictionary with multiple values of latitude and longitude keys. //Hope this helps you.
