    copied!<p>I'm getting the wrong annotation location on <code>Mapview</code>. I have tried so many things, but with no luck. I'm getting the right coordinate but it's displayed at the wrong location on mapview. Does anyone know why?</p> <pre><code> for(WatchEntityLocation *watchEntityLocation in watchEntityLocationList) { locationArray=watchEntityLocation.locationList; NSLog(@"location count:%i",[locationArray count]); Location *location=[locationArray objectAtIndex:0]; NSLog(@"watcher latlong:%g,%g",location.latitude,location.longitude); CLLocationCoordinate2D coordinate= CLLocationCoordinate2DMake(location.latitude,location.longitude); if (CLLocationCoordinate2DIsValid(coordinate)) { NSLog(@"valid Cordinate!"); } else { NSLog(@"Invalid Cordinate!"); } NSLog(@"latitude is::%g" , coordinate.latitude); NSLog(@"longitude is: :%g" , coordinate.longitude); MKCoordinateRegion viewRegion = MKCoordinateRegionMakeWithDistance(coordinate, 0.5*METERS_PER_MILE, 0.5*METERS_PER_MILE); MKCoordinateRegion adjustedRegion = [mapView regionThatFits:viewRegion]; NSLog(@"adjustedRegion latitude is::%g" , adjustedRegion.center.latitude); NSLog(@"adjustedRegion longitude is: :%g" ,adjustedRegion.center.longitude); if ((adjustedRegion.center.latitude &gt;= -90) &amp;&amp; (adjustedRegion.center.latitude &lt;= 90) &amp;&amp; (adjustedRegion.center.longitude &gt;= -180) &amp;&amp; (adjustedRegion.center.longitude &lt;= 180)){ NSLog(@"valid region!"); [mapView setRegion:adjustedRegion animated:YES]; mapView.showsUserLocation = NO; }else{ NSLog(@"Invalid region!"); } [self addAnnotation:adjustedRegion.center tlocation:watchEntityLocation.watchEntity.name];} -(void)addAnnotation:(CLLocationCoordinate2D)lcordinate tlocation:(NSString *)name { MyAnnotation *annotation = [[MyAnnotation alloc] initWithCoordinates:lcordinate title:name subTitle:@""]; annotation.pinColor = MKPinAnnotationColorGreen; [mapView addAnnotation:annotation]; [annotationArray addObject:annotation]; } - (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views { for (MKAnnotationView *av in views) { id &lt;MKAnnotation&gt; mp = [av annotation]; if (![mp isKindOfClass:[MKUserLocation class]]) { [mv selectAnnotation:mp animated:YES]; break; } } } - (MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id &lt;MKAnnotation&gt;)annotation { if ([annotation isKindOfClass:[MKUserLocation class]]) return nil; if(annotation != map.userLocation) { MKPinAnnotationView *annView=[[MKPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:@"MyPin"]; annView.animatesDrop=TRUE; annView.canShowCallout = YES; [annView setSelected:YES]; annView.pinColor = MKPinAnnotationColorRed; annView.calloutOffset = CGPointMake(15, 15); return annView; } </code></pre>
