AI-generated Key Takeaways

• GMSNavigationMutableRoutingOptions allows customization of route calculation logic, such as prioritizing routes by time or distance using the routingStrategy property.

• It enables control over alternate route generation with the alternateRoutesStrategy property.

• Developers can specify target distances for route ranking using the targetDistancesMeters property, primarily for the initial destination.

• This mutable class inherits from GMSNavigationRoutingOptions and provides flexibility in defining navigation behavior.

GMSNavigationMutableRoutingOptions

@interface GMSNavigationMutableRoutingOptions : GMSNavigationRoutingOptions

A mutable class that contains options related to routing logic (e.g., routing strategy).

• routingStrategy

  Specifies the ranking order of routes, either by time, or by distance.

  Declaration

  Swift

  var routingStrategy: GMSNavigationRoutingStrategy { get set }

  Objective-C

  @property (nonatomic) GMSNavigationRoutingStrategy routingStrategy;

• alternateRoutesStrategy

  The alternate routes strategy used when setting destinations.

  Declaration

  Swift

  var alternateRoutesStrategy: GMSNavigationAlternateRoutesStrategy { get set }

  Objective-C

  @property (nonatomic) GMSNavigationAlternateRoutesStrategy alternateRoutesStrategy;

• targetDistancesMeters

  Target distances used to ranking the routes. The elements should be non-negative integers. Don’t set GMSNavigationAlternateRoutesStrategy and this field at the same time. Target distance is only supported for the first destination for now. So only put one positive integer in the array. If the first element is not a positive integer, the routing strategy defaults to the best routing strategy.

  Declaration

  Swift

  var targetDistancesMeters: [NSNumber]? { get set }

  Objective-C

  @property (nonatomic, copy, nullable) NSArray<NSNumber *> *targetDistancesMeters;
