高德地图的使用

高德地图的使用

1.库的配置

    /***************高德地图***************

     1.库的配置  --> 导入文件，添加头文件

            libstdc++.6.0.9

            QuartzCore

            CoreLocation

            SystemCOnfiguration

            libz

            OpenGLES

            CoreTelePhony

            Security

 /*需要在Other Link Flags添加-Objc,

     静态库中实现了一些类别，会与系统有出入，所以需要标记-Objc

*/

#import "ViewController.h"

#import <MAMapKit/MAMapKit.h>

#import <AMapSearchKit/AMapSearchAPI.h>



@interface ViewController ()<MAMapViewDelegate,CLLocationManagerDelegate,UIGestureRecognizerDelegate,UISearchBarDelegate,AMapSearchDelegate>

{



    CLLocationManager *_manager;

    MAMapView *_mapView;

    

    AMapSearchAPI *_search;

}

@end

2.初始化

#import "AppDelegate.h"

#import <MAMapKit/MAMapKit.h>

#import <AMapSearchKit/AMapSearchAPI.h>   //



@interface AppDelegate ()



@end



@implementation AppDelegate





- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

    // Override point for customization after application launch.

    

    [MAMapServices sharedServices].apiKey = @"db7d1a8f64d847ff49620ff13eed023c";   //初始化

    

     // 注：  INVALID User Scode

        --> 原因： 申请的key太新 ，10分钟内申请

                  key 与应用bundle Id 不一致

     */

3.创建和显示地图

#pragma mark - 请求定位服务

-(void)requestAccessLocation{



    if(![CLLocationManager locationServicesEnabled]){

    

        NSLog(@"定位服务不可用");

        return;

    }

    _manager = [[CLLocationManager alloc] init];



    _manager.delegate = self;

    //此方法若没有 返回，直接授权

    [_manager requestAlwaysAuthorization];  //

}

-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{



    NSLog(@"status = %d",status);

}



#pragma mark - 创建和显示地图

-(void)createAndShowMap{



    _mapView = [[MAMapView alloc] initWithFrame:self.view.bounds];

    _mapView.delegate = self;

    

    [self.view addSubview:_mapView];

    

    //常用设置

    _mapView.mapType = MAMapTypeStandard;

    _mapView.userTrackingMode = MAUserTrackingModeFollowWithHeading;  //设置用户追踪模式

    _mapView.zoomLevel = 16;         //缩放级别

    

    NSLog(@"%f %f",_mapView.maxZoomLevel,_mapView.minZoomLevel);  //

}

4.地图标记（长按添加大头针）

    //4.地图标记（大头针）--> 长按 加

    UILongPressGestureRecognizer *longPress = [[UILongPressGestureRecognizer alloc] initWithTarget:self action:@selector(dealLongPress:)];

    longPress.delegate = self;   //version 不同 需加上

    [_mapView addGestureRecognizer:longPress];

    

    //添加searchBar 实现搜索功能

     _search = [[AMapSearchAPI alloc] initWithSearchKey:@"db7d1a8f64d847ff49620ff13eed023c" Delegate:self];   //搜索服务

#pragma mark - 地图标记

-(void)dealLongPress:(UILongPressGestureRecognizer *)longPress{



    if(longPress.state == UIGestureRecognizerStateBegan){

    

        //获取长按点

        CGPoint point = [longPress locationInView:_mapView];

        CLLocationCoordinate2D coordinate = [_mapView convertPoint:point toCoordinateFromView:_mapView];

        //添加大头针

        MAPointAnnotation *annotation = [[MAPointAnnotation alloc] init];

        annotation.coordinate = coordinate;

        annotation.title = @"点击位置";

        annotation.subtitle = [NSString stringWithFormat:@"%.3f,%.3f",annotation.coordinate.longitude,annotation.coordinate.latitude];

        NSLog(@"s = %@",annotation.subtitle);

        [_mapView addAnnotation:annotation];

    }

}

//显示大头针的详细信息

-(MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation{



    static NSString *annotationId = @"annotation";

    MAPinAnnotationView *pin = (MAPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:annotationId];

    if(!pin){

    

        pin = [[MAPinAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:annotationId];

    }

    pin.canShowCallout = YES;   //

    pin.pinColor = MAPinAnnotationColorGreen;

    return pin;

}

　　注：iOS8.0需加此方法

#pragma mark - 长按显示大头针（iOS8.0以上需加）

//UIGestureRecognizerDelegate  --> 加长按显示大头针

-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{



    return YES;

}

5.区域搜索  ---> 高德地图官网

 //添加searchBar 实现搜索功能

     _search = [[AMapSearchAPI alloc] initWithSearchKey:@"db7d1a8f64d847ff49620ff13eed023c" Delegate:self];   //搜索服务

    

    /****高德地图官网 -- 开发者文档(POI)****/

    //5.区域搜索

    CGSize size = [UIScreen mainScreen].bounds.size;

    UISearchBar *bar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, size.height, 40)];

    bar.delegate = self;  //

    [self.view addSubview:bar];

#pragma mark - 实现周边的搜索

-(void)aroundSearchWithKey:(NSString *)key{



    //...........

    AMapPlaceSearchRequest *poiRequest = [[AMapPlaceSearchRequest alloc] init];

    poiRequest.searchType = AMapSearchType_PlaceAround;

    poiRequest.keywords = key;

    poiRequest.city = @[@"guangzhou"];

    poiRequest.location = [AMapGeoPoint locationWithLatitude:_mapView.centerCoordinate.latitude longitude:_mapView.centerCoordinate.longitude];  //

    poiRequest.radius = 500;  //

    poiRequest.requireExtension = YES;

    

    //发起POI搜索

    [_search AMapPlaceSearch: poiRequest];



}

//实现POI搜索对应的回调函数

- (void)onPlaceSearchDone:(AMapPlaceSearchRequest *)request response:(AMapPlaceSearchResponse *)response

{

    if(response.pois.count == 0)

    {

        return;

    }

    NSLog(@"搜索个数: %ld",response.count);

    for(AMapPOI *p in response.pois){

    

        NSLog(@"name = %@, long = %f, lat = %f",p.name,p.location.longitude,p.location.latitude);

        //添加大头针

        MAPointAnnotation *point = [[MAPointAnnotation alloc] init];

        point.coordinate = CLLocationCoordinate2DMake(p.location.latitude, p.location.longitude);

        point.title = p.name;

        point.subtitle = [NSString stringWithFormat:@"经度long = %f,纬度lat = %f",p.location.longitude,p.location.latitude];

        [_mapView addAnnotation:point];

    }

  //原有的代码

/*

    //通过AMapPlaceSearchResponse对象处理搜索结果

    NSString *strCount = [NSString stringWithFormat:@"count: %d",response.count];

    NSString *strSuggestion = [NSString stringWithFormat:@"Suggestion: %@", response.suggestion];

    NSString *strPoi = @"";

    for (AMapPOI *p in response.pois) {

        strPoi = [NSString stringWithFormat:@"%@\nPOI: %@", strPoi, p.description];

    }

    NSString *result = [NSString stringWithFormat:@"%@ \n %@ \n %@", strCount, strSuggestion, strPoi];

    NSLog(@"Place: %@", result);

 */

}

6.路径规划

//UISearchBarDelegate

-(void)searchBarSearchButtonClicked:(UISearchBar *)searchBar{



    NSLog(@"search key = %@",searchBar.text);  //

  //  [self aroundSearchWithKey:searchBar.text];   //周边的搜索

   

#pragma mark 路径搜索

    //构造AMapNavigationSearchRequest对象，配置查询参数

    AMapNavigationSearchRequest *naviRequest= [[AMapNavigationSearchRequest alloc] init];

    naviRequest.searchType = AMapSearchType_NaviDrive;

    naviRequest.requireExtension = YES;

    naviRequest.origin = [AMapGeoPoint locationWithLatitude:23.174659 longitude:113.341038];

    naviRequest.destination = [AMapGeoPoint locationWithLatitude:23.174659 longitude:113.341038];

    

    //发起路径搜索

    [_search AMapNavigationSearch: naviRequest];

}

//实现路径搜索的回调函数

- (void)onNavigationSearchDone:(AMapNavigationSearchRequest *)request response:(AMapNavigationSearchResponse *)response

{

    if(response.route == nil)

    {

        return;

    }

    

    //通过AMapNavigationSearchResponse对象处理搜索结果

    NSString *route = [NSString stringWithFormat:@"Navi: %@", response.route];

    NSLog(@"%@", route);

}
