高德地圖的使用

1.庫的配置

    /***************高德地圖***************
     1.庫的配置  --> 導入文件，添加頭文件
            libstdc++.6.0.9
            QuartzCore
            CoreLocation
            SystemCOnfiguration
            libz
            OpenGLES
            CoreTelePhony
            Security

 /*需要在Other Link Flags添加-Objc,
     靜態庫中實現了一些類別，會與系統有出入，所以需要標記-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： 申請的key太新 ，10分鐘內申請
                  key 與應用bundle Id 不一致
     */

3.創建和顯示地圖

#pragma mark - 請求定位服務
-(void)requestAccessLocation{

    if(![CLLocationManager locationServicesEnabled]){
    
        NSLog(@"定位服務不可用");
        return;
    }
    _manager = [[CLLocationManager alloc] init];

    _manager.delegate = self;
    //此方法若沒有 返回，直接授權
    [_manager requestAlwaysAuthorization];  //
}
-(void)locationManager:(CLLocationManager *)manager didChangeAuthorizationStatus:(CLAuthorizationStatus)status{

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

#pragma mark - 創建和顯示地圖
-(void)createAndShowMap{

    _mapView = [[MAMapView alloc] initWithFrame:self.view.bounds];
    _mapView.delegate = self;
    
    [self.view addSubview:_mapView];
    
    //常用設置
    _mapView.mapType = MAMapTypeStandard;
    _mapView.userTrackingMode = MAUserTrackingModeFollowWithHeading;  //設置用戶追蹤模式
    _mapView.zoomLevel = 16;         //縮放級別
    
    NSLog(@"%f %f",_mapView.maxZoomLevel,_mapView.minZoomLevel);  //
}

4.地圖標記（長按添加大頭針）

    //4.地圖標記（大頭針）--> 長按 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 實現搜索功能
     _search = [[AMapSearchAPI alloc] initWithSearchKey:@"db7d1a8f64d847ff49620ff13eed023c" Delegate:self];   //搜索服務

#pragma mark - 地圖標記
-(void)dealLongPress:(UILongPressGestureRecognizer *)longPress{

    if(longPress.state == UIGestureRecognizerStateBegan){
    
        //獲取長按點
        CGPoint point = [longPress locationInView:_mapView];
        CLLocationCoordinate2D coordinate = [_mapView convertPoint:point toCoordinateFromView:_mapView];
        //添加大頭針
        MAPointAnnotation *annotation = [[MAPointAnnotation alloc] init];
        annotation.coordinate = coordinate;
        annotation.title = @"點擊位置";
        annotation.subtitle = [NSString stringWithFormat:@"%.3f,%.3f",annotation.coordinate.longitude,annotation.coordinate.latitude];
        NSLog(@"s = %@",annotation.subtitle);
        [_mapView addAnnotation:annotation];
    }
}
//顯示大頭針的詳細信息
-(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 - 長按顯示大頭針（iOS8.0以上需加）
//UIGestureRecognizerDelegate  --> 加長按顯示大頭針
-(BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldRecognizeSimultaneouslyWithGestureRecognizer:(UIGestureRecognizer *)otherGestureRecognizer{

    return YES;
}

5.區域搜索 ---> 高德地圖官網

 //添加searchBar 實現搜索功能
     _search = [[AMapSearchAPI alloc] initWithSearchKey:@"db7d1a8f64d847ff49620ff13eed023c" Delegate:self];   //搜索服務
    
    /****高德地圖官網 -- 開發者文檔(POI)****/
    //5.區域搜索
    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 - 實現周邊的搜索
-(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;
    
    //發起POI搜索
    [_search AMapPlaceSearch: poiRequest];

}
//實現POI搜索對應的回調函數
- (void)onPlaceSearchDone:(AMapPlaceSearchRequest *)request response:(AMapPlaceSearchResponse *)response
{
    if(response.pois.count == 0)
    {
        return;
    }
    NSLog(@"搜索個數: %ld",response.count);
    for(AMapPOI *p in response.pois){
    
        NSLog(@"name = %@, long = %f, lat = %f",p.name,p.location.longitude,p.location.latitude);
        //添加大頭針
        MAPointAnnotation *point = [[MAPointAnnotation alloc] init];
        point.coordinate = CLLocationCoordinate2DMake(p.location.latitude, p.location.longitude);
        point.title = p.name;
        point.subtitle = [NSString stringWithFormat:@"經度long = %f,緯度lat = %f",p.location.longitude,p.location.latitude];
        [_mapView addAnnotation:point];
    }
  //原有的代碼
/*
    //通過AMapPlaceSearchResponse對象處理搜索結果
    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:@"%@
POI: %@", strPoi, p.description];
    }
    NSString *result = [NSString stringWithFormat:@"%@ 
 %@ 
 %@", strCount, strSuggestion, strPoi];
    NSLog(@"Place: %@", result);
 */
}

6.路徑規劃

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

    NSLog(@"search key = %@",searchBar.text);  //
  //  [self aroundSearchWithKey:searchBar.text];   //周邊的搜索
   
#pragma mark 路徑搜索
    //構造AMapNavigationSearchRequest對象，配置查詢參數
    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];
    
    //發起路徑搜索
    [_search AMapNavigationSearch: naviRequest];
}
//實現路徑搜索的回調函數
- (void)onNavigationSearchDone:(AMapNavigationSearchRequest *)request response:(AMapNavigationSearchResponse *)response
{
    if(response.route == nil)
    {
        return;
    }
    
    //通過AMapNavigationSearchResponse對象處理搜索結果
    NSString *route = [NSString stringWithFormat:@"Navi: %@", response.route];
    NSLog(@"%@", route);
}
