当然因为有需求喽。
疯狂试探
- (BOOL)canOpenURL:(NSURL *)url NS_AVAILABLE_IOS(3_0);
常用地图应用的url Scheme：
//百度地图
baidumap
//高德地图
iosamap
//谷歌地图
comgooglemaps
//腾讯地图
qqmap
//其他地图省略
….
苹果地图不需要，iOS API提供了一个跳转打开方法。
注意IOS9之后，plist里面设置url scheme白名单
LSApplicationQueriesSchemes
qqmap
comgooglemaps
iosamap
baidumap
在下用的是高德坐标
高德转坐标类型枚举
// AMapCoordinateTypeBaidu = 0, ///在下试过转百度用AMapCoordinateTypeBaidu，这样一一对应的方式转，但跳转之后误差很大，后来我试着杂交匹配一下，所有地图使用Google转法最准，所以除高德地图都用了Google转出的坐标
重点来了！！！！

关于转换坐标，如果你用的是高德坐标系，除了高德地图不用转坐标系外，其他的都以高德sdk里转Google的方式转，保证目的地精确。
其他的就自己探索咯！
建议 第三方的转换方法【github】地址，找不到合适的尝试这个。
谢谢！
