  简介

  IOS地图帮助我们定位位置,IOS地图使用 MapKit 框架。

  实例步骤

  1.创建一个简单的 View based application

  2.选择项目文件,然后选择目标,然后添加MapKit.framework.

  3.添加 Corelocation.framework

  4.向 ViewController.xib 添加地图查看和创建 ibOutlet 并且命名为mapView。

  5.通过"File-> New -> File... -> "选择 Objective C class创建一个新的文件,单击下一步

  6."sub class of"为 NSObject,类作命名为MapAnnotation

  7.选择创建

  8.更新MapAnnotation.h ,如下所示

  #import

  #import

  @interface MapAnnotation : NSObject

  @property (nonatomic, strong) NSString *title;

  @property (nonatomic, readwrite) CLLocationCoordinate2D coordinate;

  - (id)initWithTitle:(NSString *)title andCoordinate:

  (CLLocationCoordinate2D)coordinate2d;

  @end

  9.更新MapAnnotation.m ,如下所示

  #import "MapAnnotation.h"

  @implementation MapAnnotation

  -(id)initWithTitle:(NSString *)title andCoordinate:

  (CLLocationCoordinate2D)coordinate2d{

  self.title = title;

  self.coordinate =coordinate2d;

  return self;

  }

  @end

  10.更新ViewController.h ,如下所示

  #import

  #import

  #import

  @interface ViewController : UIViewController{

  MKMapView *mapView;

  }

  @end

  11.更新ViewController.m ,如下所示

  #import "ViewController.h"

  #import "MapAnnotation.h"@interface ViewController ()

  @end

  @implementation ViewController

  - (void)viewDidLoad{

  [super viewDidLoad];

  mapView = [[MKMapView alloc]initWithFrame:

  CGRectMake(10, 100, 300, 300)];

  mapView.delegate = self;

  mapView.centerCoordinate = CLLocationCoordinate2DMake(37.32, -122.03);

  mapView.mapType = MKMapTypeHybrid;

  CLLocationCoordinate2D location;

  location.latitude = (double) 37.332768;

  location.longitude = (double) -122.030039;

  // Add the annotation to our map view

  MapAnnotation *newAnnotation = [[MapAnnotation alloc]

  initWithTitle:@"Apple Head quaters" andCoordinate:location];

  [mapView addAnnotation:newAnnotation];

  CLLocationCoordinate2D location2;

  location2.latitude = (double) 37.35239;

  location2.longitude = (double) -122.025919;

  MapAnnotation *newAnnotation2 = [[MapAnnotation alloc]

  initWithTitle:@"Test annotation" andCoordinate:location2];

  [mapView addAnnotation:newAnnotation2];

  [self.view addSubview:mapView];

  }

  // When a map annotation point is added, zoom to it (1500 range)

  - (void)mapView:(MKMapView *)mv didAddAnnotationViews:(NSArray *)views{

  MKAnnotationView *annotationView = [views objectAtIndex:0];

  id mp = [annotationView annotation];

  MKCoordinateRegion region = MKCoordinateRegionMakeWithDistance

  ([mp coordinate], 1500, 1500);

  [mv setRegion:region animated:YES];

  [mv selectAnnotation:mp animated:YES];

  }

  - (void)didReceiveMemoryWarning{

  [super didReceiveMemoryWarning];

  // Dispose of any resources that can be recreated.

  }

  @end
