MKMapView #iOS

创建地图

#import <MapKit/MapKit.h>

1.创建地图对象，设为属性，方便使用

@property (nonatomic,strong) MKMapView *mapView;

    self.mapView =[[MKMapViewalloc]
    initWithFrame:self.view.bounds];
    self.mapView.delegate = self;
    [self.view addSubview:self.mapView];

2.设置经纬度坐标，地图区域

    //设置经纬度坐标
    CLLocationCoordinate2D coordinate2D = CLLocationCoordinate2DMake(30.662221, 104.041367);
    //设置地图范围
    MKCoordinateSpan span = MKCoordinateSpanMake(0.01, 0.01);
    //设置整个显示的区域
    MKCoordinateRegion region = MKCoordinateRegionMake(coordinate2D, span);
    [self.mapView setRegion:region];

做完以上操作便能出现地图了。

实时的更新地图

1.创建位置管理器，设为属性
@property (nonatomic,strong) CLLocationManager *manager;

  self.manager = [[CLLocationManager alloc] init];
    //设置代理
    self.manager.delegate = self;
    //更新事件的最小距离
    self.manager.distanceFilter = 10.0;
    //在plist文件中添加一个价值对NSLocationAlwaysUsageDescription : YES
    //授权
    [self.manager requestAlwaysAuthorization];
    [self.manager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
    //获取更新后的位置信息
    CLLocation *loc = [locations firstObject];

    [UIView animateWithDuration:1.0 animations:^{
        //重新设置地图区域
        [self.mapView setRegion:MKCoordinateRegionMake(loc.coordinate, MKCoordinateSpanMake(0.01, 0.01))];
    }];
}
