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);
}
