Route Serialization

Route serialization is a feature that allows users to use NMARoute methods to serialize a route into NSData, which can be saved as a file. You can also use NMARoute to generate a route from a previously serialized route without going through the route calculation process. This is useful when a user wants to recover from a crash during navigation or when a user wants to transfer a route from another device.

Note: Route serialization is currently offered as a beta feature. APIs may change without notice.

Route serialization currently only supports car , truck, bike, and pedestrian routes. Public Transit, Indoor Venue, and Urban Mobility routes cannot be serialized. Route serialization also does not work when the map version from which a route is serialized does not match the current map version. Route serialization also fails if the binary data containing the serialized route is tempered with or corrupted. In these cases, a specific NMARouteSerializationError error code is returned.

Both asynchronous and synchronous operations are supported. To asynchronously serialize a route, perform the following:

NMARoute* route;
//assume that route calculation was already performed

// asynchronous serialization
[NMARoute serializedRouteWithCompletionBlock^(NSData *data, NSError *error) {
  // do something with the data
}];

To asynchronously deserialize a route:

NSData* data;
//assume 'data' is pointing to a previously-serialized route

[NMARoute routeFromSerializedRoute:data withCompletion:^(NMARoute *restoredRoute, NSError *error) {
  //do something with the restored route
}];
