iOS地图

引入系统库
- @import MapKit; 地图
- @import CoreLocation;定位

MKMapView

mapType ---地图类型

MKMapTypeStandard = 0, // 标准
MKMapTypeSatellite, // 卫星
MKMapTypeHybrid, // 混合（标准+卫星）
MKMapTypeSatelliteFlyover NS_ENUM_AVAILABLE(10_11, 9_0), // 3D立体卫星
MKMapTypeHybridFlyover NS_ENUM_AVAILABLE(10_11, 9_0), // 3D立体混合
MKCoordinateRegion region ， - 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;

typedef struct {
CLLocationDegrees latitudeDelta; // 纬度跨度
CLLocationDegrees longitudeDelta; // 经度跨度
} MKCoordinateSpan;
- (void)setRegion:(MKCoordinateRegion)region animated:(BOOL)animated;

设置地图显示区域
这里会更改地图的缩放等级
如不想更改缩放等级可以用setCenterCoordinate
- (MKCoordinateRegion)regionThatFits:(MKCoordinateRegion)region;

某些情况下，我们要调整region ，为了更好的显示在手机屏幕上
CLLocationCoordinate2D centerCoordinate - 地图的中心点
MKMapRect visibleMapRect; 第二方法种创建地图显示范围，一块矩形范围常常用于地图截图属性size赋值
mapRectThatFits 同 regionThatFits
MKMapCamera *camera 3D视角类似于地图街景，增强用户体验
把地图坐标转化为view上的point

- (CGPoint)convertCoordinate:(CLLocationCoordinate2D)coordinate toPointToView:(nullable UIView *)view;
把view上的point 转化为地图上的坐标点
- (CLLocationCoordinate2D)convertPoint:(CGPoint)point toCoordinateFromView:(nullable UIView *)view;
地图显示区域转化为view上的矩形范围
- (CGRect)convertRegion:(MKCoordinateRegion)region toRectToView:(nullable UIView *)view;
view上的矩形范围抓化为地图上的显示区域
- (MKCoordinateRegion)convertRect:(CGRect)rect toRegionFromView:(nullable UIView *)view;
是否可以缩放
@property (nonatomic, getter=isZoomEnabled) BOOL zoomEnabled;
是否可以拖拽
@property (nonatomic, getter=isScrollEnabled) BOOL scrollEnabled;
是否可以旋转
@property (nonatomic, getter=isRotateEnabled) BOOL rotateEnabled NS_AVAILABLE(10_9, 7_0) __TVOS_PROHIBITED;
是否显示3DVIEW
@property (nonatomic, getter=isPitchEnabled) BOOL pitchEnabled NS_AVAILABLE(10_9, 7_0) __TVOS_PROHIBITED;
是否显示罗盘（指南针）
@property (nonatomic) BOOL showsCompass NS_AVAILABLE(10_9, 9_0) __TVOS_PROHIBITED;
是否可以缩放
@property (nonatomic) BOOL showsScale NS_AVAILABLE(10_10, 9_0);
是否显示比例尺
@property (nonatomic) BOOL showsPointsOfInterest NS_AVAILABLE(10_9, 7_0); // Affects MKMapTypeStandard and MKMapTypeHybrid
是否显示建筑物
@property (nonatomic) BOOL showsBuildings NS_AVAILABLE(10_9, 7_0); // Affects MKMapTypeStandard
是否显示路况
@property (nonatomic) BOOL showsTraffic NS_AVAILABLE(10_11, 9_0); // Affects MKMapTypeStandard and MKMapTypeHybrid
是否获取用户当前位置信息
@property (nonatomic) BOOL showsUserLocation;
用户大头针，不能直接实例化，可用map.userLocation获得
@property (nonatomic, readonly) MKUserLocation *userLocation;
设置用户定位模式
@property (nonatomic) MKUserTrackingMode userTrackingMode NS_AVAILABLE(NA, 5_0);
MKUserTrackingMode 枚举：
MKUserTrackingModeNone 不定位
MKUserTrackingModeFollow 定位
MKUserTrackingModeFollowWithHeading 定位并且显示方向
用户坐标是否可见
@property (nonatomic, readonly, getter=isUserLocationVisible) BOOL userLocationVisible;
Returns YES if the user's location is displayed within the currently visible map region.
添加标注 annotations 是地图标注的模型 每次添加标注都会触发代理mapView:viewForAnnotation:得到标注view MKAnnotationView
- (void)addAnnotation:(id <MKAnnotation>)annotation;
- (void)addAnnotations:(NSArray<id<MKAnnotation>> *)annotations;
移除标注
- (void)removeAnnotation:(id <MKAnnotation>)annotation;
- (void)removeAnnotations:(NSArray<id<MKAnnotation>> *)annotations;
获取所有的标注
@property (nonatomic, readonly) NSArray<id<MKAnnotation>> *annotations;
获取某个范围内所有的标注
- (NSSet<id<MKAnnotation>> *)annotationsInMapRect:(MKMapRect)mapRect NS_AVAILABLE(10_9, 4_2);
根据特定的annotation 获取标注view 当annotation 为空，或者标注view没有显示在map上时返回nil
- (nullable MKAnnotationView *)viewForAnnotation:(id <MKAnnotation>)annotation;
从缓存池中查找指定ID的自定义大头针模型主要用于代理- (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation:(id<MKAnnotation>)annotation中，创建标注view
- (nullable MKAnnotationView *)dequeueReusableAnnotationViewWithIdentifier:(NSString *)identifier;
代码选中标注view 同时出发代理方法- (void)mapView:(MKMapView *)mapView didSelectAnnotationView:(MKAnnotationView *)view如果此时标注view在屏幕外面，则此方法失效
- (void)selectAnnotation:(id <MKAnnotation>)annotation animated:(BOOL)animated;
代码取消选中标注view 触发代理 - (void)mapView:(MKMapView *)mapView didDeselectAnnotationView:(MKAnnotationView *)view NS_AVAILABLE(10_9, 4_0);
- (void)deselectAnnotation:(nullable id <MKAnnotation>)annotation animated:(BOOL)animated;
获取所有选中的标注
@property (nonatomic, copy) NSArray<id<MKAnnotation>> *selectedAnnotations;
当前显示的注释视图的可见的矩形区域
@property (nonatomic, readonly) CGRect annotationVisibleRect;
在代理方法mapView:didAddAnnotationViews:中，可以做添加标注view动画，这个时候会用到annotationVisibleRect 点击查看demo
尽可能的显示所有的标注view
- (void)showAnnotations:(NSArray<id<MKAnnotation>> *)annotations animated:(BOOL)animated NS_AVAILABLE(10_9, 7_0);

@interface MKMapView (OverlaysAPI)
