I have not been able to find any samples that use AGSGeometryEngine projectGeometry: toSpatialReference:. Xcode is telling me that it cannot find a method named projectGeometry:toSpatialReference. The warning messages are: warning: Semantic Issue: Class method '+projectGeometry:toSpatialReference:' not found (return type defaults to 'id') 'AGSGeometryEngine' may not respond to '+projectGeometry:toSpatialReference:' Here is the code that generates the warning: (please note that myPoint is an AGSPoint...a type of AGSGeometry with it's spatial reference being 4326 (WGS1984)) AGSPoint *myPointReprojected; myPointReprojected = [AGSGeometryEngine projectGeometry:myPoint                                    toSpatialReference:[AGSSpatialReference webMercatorSpatialReference]]; Thank you for even the smallest amount of help, Paul Lohr ...

Xcode 3.2 iOS SDK 4.2 ArcGIS for iOS SDK 2.0 I have lines in a comma-separated text file that I am reading into AGSPoints then putting the AGSPoints into AGSGraphics. The lines contain X and Y values. I push each AGSGraphic into an AGSGraphicsLayer. The problem is the AGSGraphic items are displaying at 0,0 on the map. Stepping through the code, the correct X and Y values are in myGraphicArray and are in myGraphicsLayer. Here is the code. Thank you for any help. MapView.h #import <UIKit/UIKit.h> #import "ArcGIS.h" @interface MapView : UIViewController {     AGSMapView *_mapView;     AGSSimpleMarkerSymbol *myMarkerSymbol;     AGSGraphicsLayer *myGraphicsLayer; } @property (nonatomic, retain) IBOutlet AGSMapView *mapView; - (void)loadPointsOnMap; @end MapView.m #import "MapView.h" #import "GPS1AppDelegate.h" #import "TextFileMgmt.h" @implementation MapView @synthesize mapView = _mapView; - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {     self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];     if (self) {         // Custom initialization         myMarkerSymbol = [[AGSSimpleMarkerSymbol alloc] init];         myMarkerSymbol = [AGSSimpleMarkerSymbol simpleMarkerSymbol];         myMarkerSymbol.color = [UIColor blueColor];     // create a graphics layer   myGraphicsLayer = [[AGSGraphicsLayer alloc] init];   myGraphicsLayer = [AGSGraphicsLayer graphicsLayer];     }     return self; } - (void)didReceiveMemoryWarning {     // Releases the view if it doesn't have a superview.     [super didReceiveMemoryWarning];         // Release any cached data, images, etc that aren't in use. } #pragma mark - View lifecycle -(void)viewDidLoad {     // get extent of points in current file including user's location     // zoom to the new extent     [super viewDidLoad];     AGSTiledMapServiceLayer *tiledLayer = [[AGSTiledMapServiceLayer alloc]                                            initWithURL:[NSURL URLWithString:@"http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer"]];     [self.mapView addMapLayer:tiledLayer withName:@"Aerial Basemap"];     [tiledLayer release];         NSLog(@"mapView: %@", self.mapView.spatialReference);         // call local method to place points on map.     [self loadPointsOnMap];     } - (void)viewDidUnload {     [super viewDidUnload];     // Release any retained subviews of the main view.     // e.g. self.myOutlet = nil; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {     // Return YES for supported orientations     return (interfaceOrientation == UIInterfaceOrientationPortrait); } -(void)loadPointsOnMap {     // alloc and init an instance of the TextFileMgmt class.     TextFileMgmt *textFileMgmt1 = [[TextFileMgmt alloc] init];         // run the parseTextFile method.     [textFileMgmt1 parseTextFile];         // now the points array should be filled with dictionary entries.             // feed each point into an AGSPoint object array.     NSMutableArray *myMarkerPointArray = [[NSMutableArray alloc] init];         NSLog(@"textFileMgmt1 dict_x_long = %@", [textFileMgmt1.points valueForKey:@"dict_x_long"]);         for ( NSDictionary *item in textFileMgmt1.points )         {             AGSPoint *myPoint = [[AGSPoint alloc] init];                         myPoint = [AGSPoint pointWithX:[[item valueForKey:@"dict_x_long"] doubleValue]                                          y:[[item valueForKey:@"dict_y_lat"] doubleValue]                           spatialReference:self.mapView.spatialReference];                         [myMarkerPointArray addObject:myPoint];             [myPoint release];         }     NSLog(@"myMarkerPointArray contains: %@", myMarkerPointArray);     // once this for loop completes, we have an NSMutableArray holding AGSPoint instances.         // feed each AGSPoint from the myMarkerPoint array into an AGSGraphic object array.     NSMutableArray *myGraphicArray = [[NSMutableArray alloc] init];         for ( AGSPoint *item in myMarkerPointArray )         {             AGSGraphic *myGraphic = [[AGSGraphic alloc] init];             myGraphic = [AGSGraphic graphicWithGeometry:item                                                  symbol:myMarkerSymbol                                              attributes:nil                                    infoTemplateDelegate:nil];                         [myGraphicArray addObject:myGraphic];             [myGraphic release];         }     NSLog(@"myGraphicArray contains: %@", myGraphicArray);     // once this for loop completes, we have an array of AGSGraphic instances.         // send the AGSGraphic array to an AGSGraphicsLayer.         for ( AGSGraphic *item in myGraphicArray )         {             NSLog(@"item contains: %@", item);             // myGraphicsLayer was created in the init method.             [myGraphicsLayer addGraphic:item];         }     // our content should be ready for the map so add the layer.     NSLog(@"myGraphicsLayer: %@", myGraphicsLayer);     [self.mapView addMapLayer:myGraphicsLayer withName:@"Graphics Layer"];     [myGraphicsLayer dataChanged];     [myGraphicsLayer release]; } - (void)dealloc {     self.mapView = nil;     [super dealloc]; } @end ...
