I'm trying to do a simple zoom to a point using AGSPoint (only providing an x, y)...I can't get it to zoom. In addition, I'm getting an error stating, " 'AGSMapView' may not respond to -showCalloutAtPoint:forGraphic:' " I've attached the method used to zoom....can anyone provide any insight for me? //clear previous results [self.graphicsLayer removeAllGraphics]; double xPoint = [[xCoords objectAtIndex:0] doubleValue]; double yPoint = [[yCoords objectAtIndex:0] doubleValue ]; AGSPoint *pt = [[AGSPoint alloc] initWithX:xPoint y:yPoint spatialReference:self.mapView.spatialReference] ; //we have one result, center at that point [self.mapView centerAtPoint:pt animated:YES]; AGSMutableEnvelope *extent = [AGSMutableEnvelope envelopeWithXmin:pt.x ymin:pt.y xmax:pt.x+10 ymax:pt.y+10 spatialReference:self.mapView.spatialReference]; [extent expandByFactor:30]; [self.mapView zoomToEnvelope:extent animated:YES]; //create a marker symbol to use in our graphic AGSPictureMarkerSymbol *marker = [AGSPictureMarkerSymbol pictureMarkerSymbolWithImageNamed:@"BluePushpin.png"]; marker.xoffset = 9; marker.yoffset = -16; marker.hotspot = CGPointMake(-9, -11); //create the callout template, used when the user displays the callout AGSCalloutTemplate *calloutTemp = [[AGSCalloutTemplate alloc]init]; //create the graphic AGSGraphic *graphic = [[AGSGraphic alloc] initWithGeometry: pt symbol:marker attributes:nil infoTemplate:calloutTemp]; //because we alloc'ed and init'ed the callout, release it. [calloutTemp release]; //add the graphic to the graphics layer [self.graphicsLayer addGraphic:graphic]; // set the width of the callout self.mapView.callout.width = 250; //show the callout [self.mapView showCalloutAtPoint:(AGSPoint *)graphic.geometry forGraphic:graphic]; [graphic release]; //since we've added graphics, make sure to redraw [self.graphicsLayer dataChanged]; }
