Hello Akshat,

I think the reason is because you didn't set the map extent when you load the mapview. The map is not taking the full height due to view is out of the level of detail (LOD).

The easy way to fix is to set a map extent, please take a look about this documentation about Navigating the map—ArcGIS Runtime SDK for iOS

Here I also shared with you a snippet about how to set a map extent under the (void)viewDidLoad function, also be careful the xmin, ymin, xmax and ymax should match with your tile map spatialReference:

// Add a basemap tiled layer
    NSURL *url = [NSURL URLWithString:@"http://services.arcgisonline.com/arcgis/rest/services/ESRI_StreetMap_World_2D/MapServer"];
    AGSTiledMapServiceLayer *tiledLayer = [AGSTiledMapServiceLayer tiledMapServiceLayerWithURL:url];
    [self.mapView addMapLayer:tiledLayer withName:@"Basemap Tiled Layer"];
   
    AGSEnvelope *envelope = [AGSEnvelope envelopeWithXmin:-124.83145667 ymin:30.49849464 xmax:-113.91375495  ymax:44.69150688  spatialReference:_mapView.spatialReference];
    [self.mapView zoomToEnvelope:envelope animated:NO];

Hope this can help.

Best Regards,

No matter what, the map need a initial extent view on the mapView. Even the world map you also have a center point to locate, right?

You can try this centerAtPoint to insatiate the mapview about the world.

    AGSPoint *newPoint = [AGSPoint pointWithX:-90 y:37 spatialReference:self.mapView.spatialReference];
    [self.mapView centerAtPoint:newPoint animated:NO];
   
    //enable wrap around
    [self.mapView enableWrapAround];
