iOS调用第三方地图App进行导航方法

前言

• App内根据手机上装载的地图App将其显示在弹出的选择框，选择对应地图跳转进入地图导航。需要用到- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);方法判断手机是否已安装相应地图App。
• 要进行跳转需要先在xcode的plist文件内将目标App的url Scheme加入白名单(LSApplicationQueriesSchemes)。

常见第三方地图App的url Scheme

• 百度地图：baidumap
• 高德地图：iosamap
• 谷歌地图：comgooglemaps
• 腾讯地图：qqmap

plist文件新增LSApplicationQueriesSchemes关键字，类型为NSArray，并在其下添加子目录，类型为NSString，内容为各地图对应的url Scheme。

白名单LSApplicationQueriesSchemes:

//导航只需要目的地经纬度，endLocation为纬度、经度的数组
