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 ...

iOS SDK version 2.0. OS X Lion version 10.7.1. Xcode 4.2 (in use). Xcode 3.2 (also installed). iOS SDK 5.0 (deployment target is 4.3). Compiler is LLVM gcc 4.2 (no automatic reference counting). After placing a breakpoint in an implementation file and running the program in the simulator, I receive a message about a missing file related to the AGS object that was referenced near that breakpoint. The program cannot continue at this point - the same error message displays if I press the "step into" button. Running the program on the simulator or device produces the same error messages. If I place a breakpoint near AGSGraphic and run the program, this message is displayed: Can't show file for current stack frame The file /build/iosbuildbot/build/iOS/ArcGIS/Classes/Core/Models/AGSGraphic.m does not exist on the file system. If I place a breakpoint near AGSTiledMapServiceLayer, this message is displayed: Can't show file for current stack frame The file /build/iosbuildbot/build/iOS/ArcGIS/Classes/Core/Models/Layers/ArcGISServer/AGSTiledMapServiceLayer.m does not exist on the file system. I found that the error messages only appear if breakpoints are present and I am stepping through the code. Using "continue" with breakpoints does not produce an error message. Without any breakpoints, the map loads just fine. I believe I have checked all the obvious settings. I reinstalled the SDK. Still the same error messages appear. Then, as a test, I started a new project (still using Xcode 4.2) from an ArcGIS iOS template.  The implementation and xib files were created as empty files (xib can't even be edited). Obviously something is not right. It seems that something may be incorrect about the installation...? Interestingly enough, if I create a new ArcGIS project with Xcode 3.2, the implementation files and xib file contain the expected content - the project can be built and run without problems.
