使用 Map API

简单的显示Google地图

 

添加MapKit.Framework框架

 

 HomeViewController.h code:

 

#import <UIKit/UIKit.h>

#import <MapKit/MapKit.h>

 

@interface HomeViewController : UIViewController{

 

    MKMapView *map;

}

 

@end

 

 

HomeViewController.m code:

 

#import "HomeViewController.h"

 

@interface HomeViewController ()

 

@end

 

@implementation HomeViewController

 

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    map = [[MKMapView alloc] initWithFrame:[self.view bounds]];

    [self.view addSubview:map];

    

}

 

- (void)dealloc{

 

    [map release];

    [super dealloc];

}

 

@end

 

锁定位置 

 

添加CoreLocation.Framework

 

  HomeViewController.h code:

 

#import <UIKit/UIKit.h>

#import <MapKit/MapKit.h>

#import <CoreLocation/CoreLocation.h> 

 

 

@interface HomeViewController : UIViewController{

 

    MKMapView *map;

}

 

@end

 

 

HomeViewController.m code:

 #import "HomeViewController.h"

 

@interface HomeViewController ()

 

@end

 

@implementation HomeViewController

 

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    map = [[MKMapView alloc] initWithFrame:[self.view bounds]];

    

    //设置地图显示模式

    //map.mapType = mkmaptype;//设置地图为卫星显示模式

    //map.mapType = MKMapTypeStandard;//显示一个标准的地图，包括街道和公路。它是一个默认值。

    map.mapType = MKMapTypeHybrid;//显示一个混合前两种情况的视图，也就是说在卫星视图上包含公路和街道的文字信息

    

    //设置地图显示当前设备所在的地理位置

    map.showsUserLocation = YES;//显示用户的位置

    

    CLLocationCoordinate2D coords = CLLocationCoordinate2DMake(32.97386, 112.54938);

    

    float zoomLevel = 0.002;

    MKCoordinateRegion region = MKCoordinateRegionMake(coords, MKCoordinateSpanMake(zoomLevel, zoomLevel));//设置位置和范围

    [map setRegion:[map regionThatFits:region] animated:YES];

    

    [self.view addSubview:map];

    

}

 

- (void)dealloc{

 

    [map release];

    [super dealloc];

}

 

@end

 

 

地图上的路径 

 HomeViewController.m code:

#import "HomeViewController.h"

 

@interface HomeViewController ()

 

@end

 

@implementation HomeViewController

 

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    map = [[MKMapView alloc] initWithFrame:[self.view bounds]];

    

    //设置地图显示模式

    map.mapType = MKMapTypeSatellite;//设置地图为卫星显示模式

    //map.mapType = MKMapTypeStandard;//显示一个标准的地图，包括街道和公路。它是一个默认值。

    //map.mapType = MKMapTypeHybrid;//显示一个混合前两种情况的视图，也就是说在卫星视图上包含公路和街道的文字信息

    

    //设置地图显示当前设备所在的地理位置

    map.showsUserLocation = YES;//显示用户的位置

    

    CLLocationCoordinate2D coords = CLLocationCoordinate2DMake(39.992616, 116.389632);

    

    float zoomLevel = 0.002;

    MKCoordinateRegion region = MKCoordinateRegionMake(coords, MKCoordinateSpanMake(zoomLevel, zoomLevel));//设置位置和范围

    [map setRegion:[map regionThatFits:region] animated:YES];

    

    [self.view addSubview:map];

    

    map.delegate = self;

    [self createRoute];

    

}

 

//定义5个点

- (void)createRoute{

 

    CLLocationCoordinate2D routeCoords[5]; 

    routeCoords[0] = CLLocationCoordinate2DMake(39.849227, 116.4083);

    routeCoords[1] = CLLocationCoordinate2DMake(39.949227, 116.395555);

    routeCoords[2] = CLLocationCoordinate2DMake(39.949227, 116.393623);

    routeCoords[3] = CLLocationCoordinate2DMake(39.949227, 116.401091);

    routeCoords[4] = CLLocationCoordinate2DMake(39.949227, 116.400833);

    

    MKPolyline *routeLine = [MKPolyline polylineWithCoordinates:routeCoords count:5];

    [map addOverlay:routeLine];

    [routeLine release];

}

 

//协议中的方法，

-(MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id<MKOverlay>)overlay{

 

    MKPolylineView *polyView = [[MKPolylineView alloc] initWithOverlay:overlay];

    polyView.strokeColor = [UIColor redColor];

    polyView.lineWidth = 5.0;

    

    return [polyView autorelease];

}

 

- (void)dealloc{

 

    [map release];

    [super dealloc];

}

 

@end

 

添加标记“大头针” 

 添加一个NSObject类，命名为CustomAnnotation

 CustomAnnotation.h code

#import <Foundation/Foundation.h>

#import <MapKit/MapKit.h>

 

@interface CustomAnnotation : NSObject

<MKAnnotation>{

    

}

 

@property (nonatomic, readonly) CLLocationCoordinate2D coordinate;//显示大头针的坐标

@property (nonatomic, retain) NSString *title;

@property (nonatomic, retain) NSString *subtitle; 

 

@end 

CustomAnnotation.m code

#import "CustomAnnotation.h"

 

@implementation CustomAnnotation

 

@synthesize coordinate, title, subtitle;

 

- (id)initWithCoordinate:(CLLocationCoordinate2D) coords{

 

    if (self = [super init]) {

        coordinate = coords;

    }

    return self;

}

 

- (void)dealloc{

 

    [title release];

    [subtitle release];

    [super dealloc];

}

 

@end

 

 修改HomeViewController.m代码

#import "HomeViewController.h"

#import "CustomAnnotation.h"

 

@interface HomeViewController ()

 

@end

 

@implementation HomeViewController

 

- (void)viewDidLoad

{

    [super viewDidLoad];

    

    map = [[MKMapView alloc] initWithFrame:[self.view bounds]];

    

    //设置地图显示模式

    map.mapType = MKMapTypeSatellite;//设置地图为卫星显示模式

    //map.mapType = MKMapTypeStandard;//显示一个标准的地图，包括街道和公路。它是一个默认值。

    //map.mapType = MKMapTypeHybrid;//显示一个混合前两种情况的视图，也就是说在卫星视图上包含公路和街道的文字信息

    

    //设置地图显示当前设备所在的地理位置

    map.showsUserLocation = YES;//显示用户的位置

    

    CLLocationCoordinate2D coords = CLLocationCoordinate2DMake(39.992616, 116.389632);

    

    float zoomLevel = 0.002;

    MKCoordinateRegion region = MKCoordinateRegionMake(coords, MKCoordinateSpanMake(zoomLevel, zoomLevel));//设置位置和范围

    [map setRegion:[map regionThatFits:region] animated:YES];

    

    [self.view addSubview:map];

    

    map.delegate = self;

    //[self createRoute];

    [self createAnnotationWithCoords:coords];

    

}

 

//定义5个点

- (void)createRoute{

 

    CLLocationCoordinate2D routeCoords[5]; 

    routeCoords[0] = CLLocationCoordinate2DMake(39.849227, 116.4083);

    routeCoords[1] = CLLocationCoordinate2DMake(39.949227, 116.395555);

    routeCoords[2] = CLLocationCoordinate2DMake(39.949227, 116.393623);

    routeCoords[3] = CLLocationCoordinate2DMake(39.949227, 116.401091);

    routeCoords[4] = CLLocationCoordinate2DMake(39.949227, 116.400833);

    

    MKPolyline *routeLine = [MKPolyline polylineWithCoordinates:routeCoords count:5];

    [map addOverlay:routeLine];

    [routeLine release];

}

 

//协议中的方法，

-(MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id<MKOverlay>)overlay{

 

    MKPolylineView *polyView = [[MKPolylineView alloc] initWithOverlay:overlay];

    polyView.strokeColor = [UIColor redColor];

    polyView.lineWidth = 5.0;

    

    return [polyView autorelease];

}

 

- (void)createAnnotationWithCoords:(CLLocationCoordinate2D) coords{

 

    CustomAnnotation *annotation = [[CustomAnnotation alloc] initWithCoordinate:coords];

    annotation.title = @"标题";

    annotation.subtitle = @"子标题";

    [map addAnnotation:annotation];

    [annotation release];

}

 

- (void)dealloc{

 

    [map release];

    [super dealloc];

}
