Operating system requirements: iOS 5.0 or later.
Mobile device: iPad.
This example displays data view as a 3D map, and also the following operations are executed:
Map topobase is set.
The number of colored map elements is set.
A dictionary of metric dimension keys is returned.
A new map setting is set - map height indicator is calculated by scale.
Executing the example requires to place the following code in the body of the executeExample method of the ViewController class (see the Displaying of Dashboard section):
// Get dashboard controller
MAExpressAnalysisReportViewController *contr = (MAExpressAnalysisReportViewController *)m_controller;
// Get express report delegate
EAReportDelegateImpl *delegate = [contr delegate];
// Get map data source
MapDataViewDatasource *dataSource = (MapDataViewDatasource *)[delegate mapDatasource];
// Get map topobase
NSData *topobase = [delegate mapTopobase];
// Create a map container
MAMapDataViewContainerController *mapContainer = [MAMapDataViewContainerController new];
// Create a 3D map
MAMapData3DViewController *map3DViewController = [[MAMapData3DViewController alloc] initWithDatasource: nil];
// Set map data source
[map3DViewController setMapDatasource: dataSource];
// Set topobase data
[map3DViewController setTopobaseWithData:topobase];
// Set 3D map delegate
[map3DViewController setDelegate: mapContainer];
// Specify that map is loaded
[map3DViewController setTag: kViewModeMap];
[mapContainer setMainViewController: map3DViewController];
// Set map container delegate
[mapContainer setDelegate: contr];
// Specify that map container is loaded
[mapContainer setTag: kViewModeMap];
// Determine map settings
NSMutableDictionary *mapSettings = [NSMutableDictionary dictionary];
// Calculate indicator height by scale
[mapSettings setValue:kMapDepthModeScale forKey:kMapDepthMode];
// Set map settings
[map3DViewController setSettings: mapSettings];
// Create an Apple map
MAMapDataBubbleViewController *bubbleViewController = [[MAMapDataBubbleViewController alloc] initWithDatasource:(MapDataViewDatasource *)delegate.mapDatasource];
// Set Apple map delegate
[bubbleViewController setDelegate: mapContainer];
[bubbleViewController setTag: kViewModeMap];
// Set topobase data
[bubbleViewController setTopobaseWithData:delegate.mapBubbleTopobase];
[mapContainer setBubbleViewController: bubbleViewController];
BOOL isDepthEnable = [MAMapData3DViewController depthEnableState];
if (isDepthEnable) {
NSLog(@"Map layer area height settings are available");
} else {
NSLog(@"Map layer area height settings are not available");
}
// Set colored map elements
[map3DViewController setStrokedShapes: [[mapContainer bubbleViewController] strokedShapes]];
NSLog(@"Number of colored map elements: %d", [[map3DViewController strokedShapes] count]);
// Delete all window subviews
NSArray *subviews = [self.parentViewController.view subviews];
for (UIView *subView in subviews) {
[subView removeFromSuperview];
}
// Display controller view
[self.parentViewController.view addSubview: [map3DViewController view]];
After executing the example the 3D map data view is displayed:
The development environment console displays notification that map layer height settings are not specified, and the number of colored map elements:
Number of colored map elements: 1
