iOS項目接入高德skd

前段時間做了個項目需要用到地圖，雖然iOS有內置的地圖API但是還是決定直接接入高德地圖，實現標註視圖的自定義。首先要按照文檔接入高德sdk這沒有什麼好說的。
看代碼。首先要創建地圖

 [MAMapServices sharedServices].apiKey = @"5071a08ef9f79377e5a929362aef916e";
 _mapView = [[MAMapView alloc] initWithFrame:CGRectMake(0, naviHeight+statrHeight+personView.frame.size.height, Swidth, Sheight-naviHeight+statrHeight+personView.frame.size.height)];
  _mapView.userTrackingMode = MAUserTrackingModeFollow;
[self.view addSubview:_mapView];

接下來是主要的創建標準視圖，第一步要創建數據源：

- (void)creatAnnotaionModel:(S2CGamedetailret *)gameModel {
    if (gameModel != nil) {
        NSMutableArray *mutableArry = [NSMutableArray array];
      ...
            //標準視圖創建
            MAPointAnnotation *annotation = [[MAPointAnnotation alloc] init];
            CLLocationCoordinate2D coorDinate = CLLocationCoordinate2DMake([[gameModel.players[i] valueForKey:@"latitude" ] doubleValue],[[gameModel.players[i] valueForKey:@"longitude" ] doubleValue]);
            annotation.coordinate = coorDinate;
            annotation.title = @"d";
            [mutableArry addObject:annotation];
      ...
        [mutableArry addObject:annotation];
        //添加地圖的標註視圖數據源
        [_mapView addAnnotations:mutableArry];

        }
}

然後要正式創建標註視圖了：

//這裏是部分代碼，函數返回的就是標註視圖了。HeadAnnotationVeiw是MAAnnotationView的一個子類
- (MAAnnotationView *)mapView:(MAMapView *)mapView viewForAnnotation:(id<MAAnnotation>)annotation {
    NSUInteger personRanking = 0;
    if ([annotation isKindOfClass:[MAPointAnnotation class]]) {
        static NSString *identy = @"annotation";
        //先從複用池中取視圖
       HeadAnnotationVeiw   *annotationView = (HeadAnnotationVeiw *)[mapView dequeueReusableAnnotationViewWithIdentifier:identy];
        if (annotationView == nil) {
            annotationView = [[HeadAnnotationVeiw alloc] initWithAnnotation:annotation reuseIdentifier:identy];
        }
        //判斷是否是登陸者的標註視圖
      ...
            annotationView.faImage.imageURL = [NSURL URLWithString:detail.loginUserInfo.headImage];
            //annotationView.selected = YES; //默認登陸者是處於選擇狀態的
            annotationView.imageName = @"map_hover_bg";
            annotationView.isPK = detail.loginUserInfo.pkIng;
            annotationView.personId = detail.loginUserInfo.id;
           ....
        }

        return annotationView;
    }
    return nil;
}

HeadAnnotationVeiw繼承自MAAnnotationView，有個初始化方法最好實現一下：

 */
- (id)initWithAnnotation:(id <MAAnnotation>)annotation reuseIdentifier:(NSString *)reuseIdentifier;

選中標註視圖

//選中標註視圖
- (void)mapView:(MAMapView *)mapView didSelectAnnotationView:(MAAnnotationView *)view {
    if ([view isKindOfClass:[HeadAnnotationVeiw class]]) {
        headView = (HeadAnnotationVeiw *)view;
        point = [headView.superview convertPoint:headView.frame.origin toView:self.view]; //獲取標註視圖在屏幕中的位置
      //區分選中的視圖可以使用經緯度
    }
}

添加標註視圖會調用這個方法

- (void)mapView:(MAMapView *)mapView didAddAnnotationViews:(NSArray *)views {
    [_mapView showAnnotations:_mapView.annotations animated:YES];
}

更新位置信息

- (void)mapView:(MAMapView *)mapView didUpdateUserLocation:(MAUserLocation *)userLocation updatingLocation:(BOOL)updatingLocation {
    static NSInteger i = 0;
    if (i >= 1) {
        return;
    }
    i ++;
    CLLocationCoordinate2D coorDinate = userLocation.coordinate;
    NSString *longitude = [NSString stringWithFormat:@"%f",coorDinate.longitude];
    NSString *latitude = [NSString stringWithFormat:@"%f",coorDinate.latitude];
    }
