I am using Skobbler Maps,
In the skobbler Framework I get all the instructions
-(void)routingService:(SKRoutingService *)routingService didChangeCurrentAdviceInstruction:(NSString *)currentAdviceInstruction nextAdviceInstruction:(NSString *)nextAdviceInstruction
In this delegate method getting all the instructions in around 5/10 meters and audio also playing. How can I customize turn by turn instructions and audio in each 100/200 meters.
