前期步骤参考谷歌官方文档
引入头文件：
#import <GoogleMaps/GoogleMaps.h>
#import <GooglePlaces/GooglePlaces.h>
引入代理协议<GMSMapViewDelegate>
1.创建地图
GMSMapView *mapView = [[GMSMapView alloc] initWithFrame:self.view.frame];
mapView.delegate = self;
[self.view addSubview: mapView];
2.定位当前位置
// 显示官方的小蓝点，但是图标无法更改
// 如果 iOS 提示用户允许他人访问此数据， 在这种情况下，它将为 nil (官方文档写的，也不解决很是郁闷)
mapView.myLocationEnabled = YES;
// 开启蓝点，可获取当前位置的坐标
NSLog(@"User's location: %@", mapView.myLocation);
上述这种方法会获取不到位置的情况，用下面一种方法代替
GMSPlacesClient *placesClient = [[GMSPlacesClient alloc] init];
[placesClient currentPlaceWithCallback:^(GMSPlaceLikelihoodList *likelihoodList, NSError *error) {
if (error != nil) {
NSLog(@"Current Place error %@", [error localizedDescription]);
return;
}
if (likelihoodList != nil) {
// 当前位置信息
GMSPlace *place = [[[likelihoodList likelihoods] lastObject] place];
if (place != nil) {
// 创建地图显示中心 zoom为缩放比例
GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:place.coordinate.latitude
longitude:place.coordinate.longitude
zoom:18];
self.mapView.camera = camera;
// 创建标记点
GMSMarker *marker = [[GMSMarker alloc] init];
marker.position = CLLocationCoordinate2DMake(place.coordinate.latitude, place.coordinate.longitude);
marker.map = mapView;
// 替换为你的图片
marker.icon = [UIImage imageNamed:@"point_gps"];
}
}
}];
3.自定义信息窗口
- (nullable UIView *) mapView:(GMSMapView *) mapView markerInfoWindow:(GMSMarker *) marker{
// DeviceInfoView自定义的信息窗口类，默认直接显示在点的中心位置
DeviceInfoView *view = [[DeviceInfoView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)];
[view initWithLocationModel:_currentLocation];
view.layer.masksToBounds = YES;
view.layer.cornerRadius = 6;
return view;
}
4. 已进入地图直接显示信息窗口
// marker 为你要显示的窗口的标记点
mapView.selectedMarker = marker;
5. 清除地图上所有的标记点和信息
[mapView clear];
6. 轨迹连线
GMSMutablePath *path = [GMSMutablePath path];
[path addCoordinate:CLLocationCoordinate2DMake(latitude1, longitude1)];
[path addCoordinate:CLLocationCoordinate2DMake(latitude2, longitude2)];
[path addCoordinate:CLLocationCoordinate2DMake(latitude3, longitude3)];
GMSPolyline *rectangle = [GMSPolyline polylineWithPath:path];
rectangle.map = mapView;
// 线的颜色
rectangle.strokeColor = HexRGB(0xBBF0FF);
// 线的宽度
rectangle.strokeWidth = 3;
7. 画圆
GMSCircle *circ = [GMSCircle circleWithPosition:marker.position
radius:半径];
// 圈内填充的颜色
circ.fillColor = [UIColor colorWithRed:0.77 green:0.88 blue:0.94 alpha:0.8];
// 圆边的颜色
circ.strokeColor = [UIColor whiteColor];
// 圆边的宽度
circ.strokeWidth = 5;
circ.map = mapView;
8. 点击地图获取位置信息
// 只获取位置坐标点
- (void)mapView:(GMSMapView *)mapView didTapAtCoordinate:(CLLocationCoordinate2D)coordinate;
// 获取位置信息详情
- (void)mapView:(GMSMapView *)mapView didTapPOIWithPlaceID:(NSString *)placeID name:(NSString *)name location:(CLLocationCoordinate2D)location;
高德简直是业界良心!
