iOS地图开发

IOS地图开发

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.

}
