iOS 地图

首先在工程里导入MapKit.framework

#import "RootViewController.h"
#import <MapKit/MapKit.h>
@interface RootViewController ()<MKMapViewDelegate>

@end

@implementation RootViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // 初始化MKMapView
    MKMapView *mapView = [[MKMapView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // 设置代理
    mapView.delegate = self;
    // 设置显示当前位置
    mapView.showsUserLocation = YES;
    // 设置地图显示类型
    mapView.mapType = MKMapTypeStandard;
    // 经纬度
    CLLocationCoordinate2D coord2D = {23.117000,113.27500};
    // 显示范围精度
    MKCoordinateSpan span = {0.01,0.01};
    // 显示区域
    MKCoordinateRegion region = {coord2D,span};
    // 给地图设置显示区域
    [mapView setRegion:region animated:YES];
    [self.view addSubview:mapView];
}
