一 进入百度官方开发者平台 -->http://developer.baidu.com/map/
然后选择 百度导航SDK -->http://developer.baidu.com/map/index.php?title=ios-navsdk/guide/introduction
然后跟着步骤来就好了
但是 遇到一个坑 导航语音播报的时候需要一个延迟 否则会导致无法成功播音播出路径规划时间的距离
//异步处理 让语音播报成功
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)( 1*NSEC_PER_SEC)), dispatch_get_main_queue(),^{
[BNCoreServices_Instance startServicesAsyn:^{
//发起路径规划
[BNCoreServices_RoutePlan startNaviRoutePlan:BNRoutePlanMode_Recommend | BN_Speak_Mode_Mid naviNodes:nodesArray time:nil delegete:self userInfo:nil];
} fail:^{
}];
});
到了这里 基本导航没多大问题 ！

友情提示 :百度语音与百度导航使用的是一个语音包 不能同时使用，官方开发人员也做出相应回答:目前无法解决 期待百度做的更好吧！
其他 细心一点就好 嘻嘻
