JZLocationConverter
Swift版本(使用边境线坐标，判断是否中国大陆)
Quick start
JZLocationConverter 支持 CocoaPods. 添加下面配置到你的 Podfile:
pod 'JZLocationConverter'WGS-84世界标准坐标、GCJ-02中国国测局(火星坐标)、BD-09百度坐标系转换 目前有:
WGS-84 -> GCJ-02
此接口当输入坐标为中国大陆以外时，仍旧返回WGS-84坐标
+ (CLLocationCoordinate2D)wgs84ToGcj02:(CLLocationCoordinate2D)location;
GCJ-02 -> WGS-84
此接口有1-2米左右的误差，需要精确的场景慎用
+ (CLLocationCoordinate2D)gcj02ToWgs84:(CLLocationCoordinate2D)location;
WGS-84 -> BD-09
+ (CLLocationCoordinate2D)wgs84ToBd09:(CLLocationCoordinate2D)location;
BD-09 -> WGS-84
+ (CLLocationCoordinate2D)bd09ToWgs84:(CLLocationCoordinate2D)location;
GCJ-02 -> BD-09
+ (CLLocationCoordinate2D)gcj02ToBd09:(CLLocationCoordinate2D)location;
BD-09 -> GCJ-02
此接口有1-2米左右的误差，需要精确的场景慎用
+ (CLLocationCoordinate2D)bd09ToGcj02:(CLLocationCoordinate2D)location;
