声明权限 设置gpx数据 二、地图基本使用 实现功能:显示地图,并且显示用户所在的位置,点击用户的位置,显示一个气泡展示用户的位置信息 代码 @interface ViewController ()<MKMapViewDelegate...实现效果 三、地图缩放级别 实现功能:在之前功能的基础上实现地图的任意视角(“缩放级别”) 代码 @interface ViewController ()...CLLocationCoordinate2D)newCoordinate; @end 控制器 @interface ViewController ()<CLLocationManagerDelegate, MKMapViewDelegate
7 #define SCREEN_HEIGHT ([UIScreen mainScreen].bounds.size.height) 8 9 @interface MapViewCtl ()<MKMapViewDelegate
"ViewController.h" #import #import "MyAnnotation.h" @interface ViewController ()<MKMapViewDelegate
今天的博客主要是介绍MKMapView的使用,MapView的使用和其他组件的用法差不多,MapView用的是委托回调,在使用mapView的Controller中要实现MKMapViewDelegate
. // Implement mapView:viewForAnnotation: on MKMapViewDelegate to return the annotation view for each...)showAnnotations:(NSArray *)annotations animated:(BOOL)animated NS_AVAILABLE(10_9, 7_0); @end 2.1.2 MKMapViewDelegate...委托接口申明 @protocol MKMapViewDelegate @optional - (void)mapView:(MKMapView *)mapView regionWillChangeAnimated...self.mapView.showsUserLocation = YES; [self.mapView setUserTrackingMode: MKUserTrackingModeFollow animated: YES]; 2.1.3.2 MKMapViewDelegate...委托处理 #pragma mark - MKMapViewDelegate 委托处理 - (MKAnnotationView *)mapView:(MKMapView *)mapView viewForAnnotation
ViewController.h" 10 #import 11 #import "HMAnnotation.h" 12 13 @interface ViewController ()<MKMapViewDelegate..."%@ %f", step.instructions, step.distance); 140 } 141 142 } 143 }]; 144 } 145 146 #pragma mark - MKMapViewDelegate
NSMutableArray *carModelArray; @end 使用到的全局变量 @interface MapView()<CLLocationManagerDelegate,MKMapViewDelegate...addObject:annotation]; count++; } } mapview自身的代理方法,点击和取消大头针,实现回调跳转车辆信息view #pragma mark - MKMapViewDelegate
property NSArray *annotations; //地图上的标记 @property MKUserLocation userLocation; //用户位置 @property id <MKMapViewDelegate...//选中标注 self.mapView.selectAnnotation(annotation, animated: true) } } 自定义图钉视图 遵循MKMapViewDelegate
extension ViewController: MKMapViewDelegate { func mapView(_ mapView: MKMapView, viewFor annotation...extension ViewController: MKMapViewDelegate { func mapView(_ mapView: MKMapView, viewFor annotation
self.mapView.centerCoordinate = self.mapView.userLocation.location.coordinate; 5.设置代理 @property (nonatomic, weak, nullable) id <MKMapViewDelegate...nullable MKAnnotationView *)dequeueReusableAnnotationViewWithIdentifier:(NSString *)identifier; ---- 代理方法:MKMapViewDelegate
readonly) NSArray *overlays; 地图覆盖物数组 - (NSArray *)overlaysInLevel:(MKOverlayLevel)level; 层级属性下的东土覆盖物数组 二、MKMapViewDelegate
statusBarFrame.size.height) #define kDefault (100) @interface ViewController () <CLLocationManagerDelegate, MKMapViewDelegate
MKMapView 有个 MKMapViewDelegate 代理方法,它具体的方法可以点进这个协议去看,里面有个方法是 - (nullable MKAnnotationView *)mapView:(
func makeCoordinator() -> Coordinator { Coordinator(self) } class Coordinator: NSObject, MKMapViewDelegate
