自定义标注视图：继承NSObject

#import <Foundation/Foundation.h>
#import <MapKit/MapKit.h>
@interface HLAnnotation : NSObject<MKAnnotation>

//MKAnnotation协议里面必须实现的属性
@property (nonatomic) CLLocationCoordinate2D coordinate;

//MKAnnotation协议里面的可选属性
@property (nonatomic,  copy) NSString *title;
@property (nonatomic,  copy) NSString *subtitle;

//设置一个tag值标记区分每一个标注视图（大头针）
@property (nonatomic) NSInteger tag ;
