IOS MapKit框架的使用(专门用于地图显示)

一、MapKit框架使用前提

导入框架
导入主头文件#import <MapKit/MapKit.h>
MapKit框架使用须知
MapKit框架中所有数据类型的前缀都是MK
MapKit有一个比较重要的UI控件 :MKMapView,专门用于地图显示

二、跟踪显示用户的位置

设置MKMapView的userTrackingMode属性可以跟踪显示用户的当前位置

MKUserTrackingModeNone :不跟踪用户的位置 

MKUserTrackingModeFollow :跟踪并在地图上显示用户的当前位置

MKUserTrackingModeFollowWithHeading :跟踪并在地图上显示用户的当前位 置,地图会跟随用户的前进方向进行旋转

下图是跟踪效果，蓝色发光圆点就是用户的当前位置。蓝色发光原点,专业术语叫做“大头针”

三、地图的类型

可以通过设置MKMapView的mapViewType设置地图类型

MKMapTypeStandard:普通地图(左图)
MKMapTypeSatellite:卫星云图(中图)
MKMapTypeHybrid:普通地图覆盖于卫星云图之上(右图)

四、MKMapView的代理

MKMapView可以设置一个代理对象,用来监听地图的相关行为

常见的代理方法有

-(void)mapView:(MKMapView*)mapViewdidUpdateUserLocation: (MKUserLocation *)userLocation; // 调用非常频繁,不断监测用户的当前位置 。每次调用,都会把用户的最新位置(userLocation参数)传进来

-(void)mapView:(MKMapView*)mapViewregionWillChangeAnimated: (BOOL)animated; //地图的显示区域即将发生改变的时候调用

-(void)mapView:(MKMapView*)mapViewregionDidChangeAnimated: (BOOL)animated;  //地图的显示区域已经发生改变的时候调用

五、MKUserLocation

MKUserLocation其实是个大头针模型,包括以下属性

@property(nonatomic,copy)NSString*title;  //显示在大头针上的标题
@property(nonatomic,copy)NSString*subtitle; // 显示在大头针上的子标题
@property(readonly,nonatomic)CLLocation*location; // 地理位置信息(大头针钉在什么地方?)

六、设置地图的显示

　　通过MKMapView的下列方法,可以设置地图显示的位置和区域

1.设置地图的中心点位置

@property (nonatomic) CLLocationCoordinate2D centerCoordinate;
- (void)setCenterCoordinate:(CLLocationCoordinate2D)coordinate
animated:(BOOL)animated;

2.设置地图的显示区域

@property (nonatomic) MKCoordinateRegion region;
- (void)setRegion:(MKCoordinateRegion)region animated:
(BOOL)animated;

七、MKCoordinateRegion

MKCoordinateRegion是一个用来表示区域的结构体,定义如下

typedef struct {
CLLocationCoordinate2D center; // 区域的中心点位置 

MKCoordinateSpan span; // 区域的跨度 

} MKCoordinateRegion;

MKCoordinateSpan的定义

typedef struct { 

CLLocationDegrees latitudeDelta; // 纬度跨度 

CLLocationDegrees longitudeDelta; // 经度跨度

} MKCoordinateSpan;

八、大头针的基本操作

-(void)addAnnotation:(id<MKAnnotation>)annotation;  //添加一个大头针 
-(void)addAnnotations:(NSArray*)annotations; //添加多个大头针

-(void)removeAnnotation:(id<MKAnnotation>)annotation; // 移除一个大头针
-(void)removeAnnotations:(NSArray*)annotations; //  移除多个大头针

(id<MKAnnotation>)annotation //大头针模型对象:用来封装大头针的数据,比如大头针的位置、标题、子标题等数据

九、大头针模型

新建一个大头针模型类
#import <MapKit/MapKit.h>
@interface MJTuangouAnnotation : NSObject <MKAnnotation>
/** 坐标位置 */
@property (nonatomic, assign) CLLocationCoordinate2D coordinate;

/** 标题 */

@property (nonatomic, copy) NSString *title;

/** 子标题 */
@property (nonatomic, copy) NSString *subtitle;

@end

十、添加大头针

MJTuangouAnnotation *anno = [[MJTuangouAnnotation alloc] init];
anno.title = @"XX超市";
anno.subtitle = @"地址:XX 公交是XX";
anno.coordinate = CLLocationCoordinate2DMake(40, 116);
[self.mapView addAnnotation:anno];

十一、自定义大头针

很多情况下,需要自定义大头针的显示样式,比如显示一张图片

设置MKMapView的代理

● 实现下面的代理方法,返回大头针控件

- (MKAnnotationView *)mapView:(MKMapView *)mapView
viewForAnnotation:(id <MKAnnotation>)annotation;
●  根据传进来的(id <MKAnnotation>)annotation参数创建并返回对应的大头针控 件 

●  代理方法的使用注意 

●  如果返回nil,显示出来的大头针就采取系统的默认样式 

●  标识用户位置的蓝色发光圆点,它也是一个大头针,当显示这个大头针时,也会调用代 理方法 

●  因此,需要在代理方法中分清楚(id <MKAnnotation>)annotation参数代表自定 义的大头针还是蓝色发光圆点 
 - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation: (id<MKAnnotation>)annotation

{

// 判断annotation的类型
if (![annotation isKindOfClass:[MJTuangouAnnotation class]]) return nil;

// 创建MKAnnotationView
static NSString *ID = @"tuangou";
MKAnnotationView *annoView = [mapView dequeueReusableAnnotationViewWithIdentifier:ID]; if (annoView == nil) {

       annoView = [[MKAnnotationView alloc] initWithAnnotation:annotation
reuseIdentifier:ID];
       annoView.canShowCallout = YES;
   }
// 传递模型数据
annoView.annotation = annotation;
 

// 设置图片
MJTuangouAnnotation *tuangouAnnotation = annotation;

annoView.image = [UIImage imageNamed:tuangouAnnotation.icon];

return annoView;
}

十二、MKAnnotationView

地图上的大头针控件是MKAnnotationView

MKAnnotationView的属性
@property(nonatomic,strong)id<MKAnnotation>annotation;  //大头针模型
@property(nonatomic,strong)UIImage*image;  //显示的图片
@property(nonatomic)BOOLcanShowCallout;     //是否显示标注
@property(nonatomic)CGPointcalloutOffset;   //标注的偏移量
@property(strong,nonatomic)UIView*rightCalloutAccessoryView;   //标注右边显示什么控件
@property(strong,nonatomic)UIView*leftCalloutAccessoryView;  //标注左边显示什么控件

十三、MKPinAnnotationView

MKPinAnnotationView是MKAnnotationView的子类
MKPinAnnotationView比MKAnnotationView多了2个属性
@property(nonatomic)MKPinAnnotationColorpinColor; //大头针颜色
@property(nonatomic)BOOLanimatesDrop;  //大头针第一次显示时是否从天而降

十四、实例：

MpaKit基本使用

/**
 CLLocation : 封装位置信息（经纬度、海拔）
 CLPlacemark : 封装地标信息（位置信息CLLocation、地名name、国家country）
 MKUserLocation : 封装地图上大头针的位置信息（位置信息CLLocation、标题title、子标题subtitle）
 CLLocationDegrees : 度数（经度、纬度）
 CLLocationCoordinate2D : 地理坐标（经度CLLocationDegrees longitude、纬度CLLocationDegrees latitude）
 MKCoordinateSpan : 跨度（经度跨度CLLocationDegrees longitudeDelta、纬度跨度CLLocationDegrees latitudeDelta）
 MKCoordinateRegion: 区域（中心位置CLLocationCoordinate2D center、区域跨度MKCoordinateSpan span）
