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 <Foundation/Foundation.h>#import <MapKit/MapKit.h>@interface MapAnnotation : NSObject<MKAnnotation>@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 <UIKit/UIKit.h>#import <MapKit/MapKit.h>#import <CoreLocation/CoreLocation.h>@interface ViewController : UIViewController<MKMapViewDelegate>{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 viewMapAnnotation 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 <MKAnnotation> 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

运行应用程序时，输出结果如下
当我们向上滚动地图时，输出结果如下
