    UILabel *m_locationName;

    MKMapView *mainMapView;

@public CLLocationCoordinate2D baidulocation;

    CLLocationCoordinate2D deleeverLocation;

}

-(void)OpenGPSmapView;

//在地图上放上自己的位置--外接接口

-(void)setMyMapPonitByMKMapView:(MKMapView *)MyMap;

@end

复制代码
@interface POI : NSObject <MKAnnotation> {

 

   

    CLLocationCoordinate2D coordinate;

    NSString *subtitle;

    NSString *title;

}

 

@property (nonatomic,readonly) CLLocationCoordinate2D coordinate;

@property (nonatomic,retain) NSString *subtitle;

@property (nonatomic,retain) NSString *title;

 

-(id) initWithCoords:(CLLocationCoordinate2D) coords;

 

@end

 

 

在GPScombineClass.m中

 

复制代码
#import "GPScombineClass.h"

 

const double x_pi = 3.14159265358979324 * 3000.0 / 180.0;

@implementation GPScombineClass

-(void)OpenGPSmapView{

    m_sqlite = [[CSqlite alloc]init];

    [m_sqlite openSqlite];

    if ([CLLocationManager locationServicesEnabled]) { // 检查定位服务是否可用
