This is a set of C# bindings for Skobbler's map SDK. I'd described the current stage as demo. We have the bindings working in simple example projects but it hasn't shipped with a real project yet. We're working hard (but a bit slowly due to other factors) to expose the entire SDK, and would eventually like to provide a single iOS/Android SDK for monotouch (if possible).
We can definitely use help, so please drop us a line if you would like to contribute, or even if there is a specific feature we aren't exposing yet that you want to use.
This repo includes version 2.4 of the Skobbler SDK. Due to some issues with the original SDK, we've had to hack it a bit to get it to work. Specifically, the original SDK included a symbol for 'main' which causes linking errors when you try to use it in your Xamarin App. If you'd like to use your own/newer version of the library, there are instructions below on how to fix it. You can also just raise an issue if we aren't on the latest version of the library and we'll upgrade.
To install, just grab a copy of this repo. Open the solution included and run one of the samples to verify that everything works. You can use it in other applications just by adding a reference to the SKMaps.dll file that the project will build.
To use this in your own applications, you'll need an API Key for the Skobbler SDK.
Simply add SKMaps.dll to your project's References and you should be ready to roll!
Perform one-time initialization of the Skobbler SDK. In AppDelegate.cs / FinishedLaunching:,
SKMapsInitSettings initSettings = SKMapsInitSettings.MapsInitSettings;
// whatwever settings you need to change here.....
initSettings.ConnectivityMode = SKConnectivityMode.Offline;
initSettings.MapDetailLevel = SKMapDetailLevel.Full;
SKMap.SKMapsService.InitializeSKMapsWithAPIKey("YOUR API KEY HERE");
In your view controller / ViewDidLoad method:
SKMapView mapView = new SKMapView (this.View.Frame);
this.View.AddSubview (mapView);
You can start adding logic to the view by adding event handlers:
mapView.DidSelectAnnotation += delegate(object sender, MapAnnotationEventArgs e) {
Console.WriteLine("Tapped {0}", e.Annotation.Identifier);
mapView.CalloutView.TitleLabel.Text = String.Format("Annotation {0} Title", e.Annotation.Identifier);
mapView.CalloutView.SubtitleLabel.Text = String.Format("Annoation {0} Subtitle Label", e.Annotation.Identifier);
mapView.ShowCalloutForAnnotation(e.Annotation, new PointF(0.0f, 42.0f), true);
};
mapView.DidTapAtCoordinate += delegate(object sender, MapLocationEventArgs e) {
Console.WriteLine("Tapped at {0}, {1}", e.Coordinate.Latitude, e.Coordinate.Longitude);
mapView.HideCallout();
};
mapView.CalloutView.DidTapLeftButton += delegate(object sender, CalloutViewLeftButtonTappedEventArgs e) {
Console.WriteLine("Tapped Left Button");
};
mapView.CalloutView.DidTapRightButton += delegate(object sender, CalloutViewRightButtonTappedEventArgs e) {
Console.WriteLine("Tapped Right Button");
};
Add some annotations to your map:
SKAnnotation annotation = SKAnnotation.Annotation;
annotation.Identifier = 10;
annotation.ImagePath = NSBundle.MainBundle.PathForResource ("customImage", "png");
annotation.ImageSize = 64;
annotation.Location = new CLLocationCoordinate2D (0, -80);
annotation.MinZoomLevel = 0;
mapView.AddAnnotation (annotation, SKAnimationSettings.DefaultAnimationSettings);
Show the Callout View for an Annotation:
mapView.ShowCalloutForAnnotation (annotation, new PointF (0.0f, 42.0f), false);
Set the 'visible region' for the map:
SKCoordinateRegion visibleRegion;
visibleRegion.center = new CLLocationCoordinate2D (0, -80);
visibleRegion.zoomLevel = 12;
mapView.VisibleRegion = visibleRegion;
Copy the framework (SKMaps.framework) into the ./SKMaps/ folder.
You'll need ruby; if you're on a mac, you should have it. Fire up terminal and run the fix_lib.rb script, which will attempt to fix a few issues with symbols in the library:
$ cd SKMaps/
$ ruby fix_lib.rbNow you should be able to open the SKMaps.sln file in Monotouch and re-compile the library (use release mode) and it will generate a new SKMaps.dll using the new version of the framework.
If you want to use custom images for your markers, here are a couple things to keep in mind:
- they must be a power-of-2 size
- if they are PNG files, you need to turn pngcrush off; you can do this in Project Options -> iOS Build -> General -> Packaging Options -> Optimize PNG Image files for iOS -- make sure this option is disabled.
There may be some spew into the console if you don't do the above, but otherwise the failures are silent (no crashes or exceptions thrown). If you notice errors like this in the console, it's likely a pngcrush issue as described above:
libpng error: CgBI: unknown critical chunk
When I was first setting up my personal project to use the SKMaps.dll, I ran into a bunch of issues where it would give linking errors on all sorts of C++ code. I've looked through the history and can't figure out what I did to fix it exactly (maybe it was just changes to the library), but if you run into this issue, please contact me and I'll walk you through it.
- Support for downloadable offline maps
- Encompass entire Skobbler API
- Unify Android/iOS interfaces in MonoTouch
