Navigation application programming interface

Navigation application programming interfaces that can be used to obtain navigation information in third party software applications are provided. In one example implementation, an application programming interface (API) can include a first set of instructions associated with a navigator class. The navigator class can specify a plurality of functions to control the implementation of a navigation service by the software application. The navigation service can provide navigation information to a user of the software application. The API can include a second set of instructions associated with anavigator delegate protocol. The navigator delegate protocol can be a delegate of the navigator class. The navigator delegate protocol can implement one or more calls to update the navigation information provided as part of the navigation service. 提供了可用来获得在第三方软件应用中的导航信息的导航应用编程接口。在个示例性实施方式中，应用编程接口(API)可以包括与导航器类相关联的第指令集。导航器类可以指定控制由软件应用实现的导航服务的多个函数。导航服务可以向软件应用的用户提供导航信息。API可以包括与导航器委托协议相关联的第二指令集。导航器委托协议可以是导航器类的委托。导航器委托协议可以实现个或
