集成谷歌地图

一、pod下载谷歌地图SDK

pod  'GoogleMaps'

  pod  'GooglePlaces'

二、初始化谷歌地图

代理   <GMSMapViewDelegate, GMSAutocompleteViewControllerDelegate>

@property (nonatomic,strong) CLLocationManager *locationManager;//地图定位对象

@property (nonatomic,strong) GMSMapView *mapView;//地图

@property (nonatomic,strong) GMSMarker *marker;//大头针

//初始化地图

GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:[_latitude floatValue] longitude:[_longitude floatValue]  zoom:12];

    self.mapView= [GMSMapView mapWithFrame:CGRectZero camera:camera];

    self.mapView.delegate = self; //注册代理属性

    self.mapView.settings.compassButton = YES;//显示指南针

    self.mapView.frame =self.view.frame;

    [self.view addSubview:self.mapView];

    if (self.locationManager == nil) {

        self.locationManager= [[CLLocationManager alloc]init];

    }

    self.locationManager.delegate = self;

    [self.locationManager requestAlwaysAuthorization];//授权方式，如果在后台也需要定位，那就选择 requestAlwaysAuthorization。

    self.locationManager.desiredAccuracy = kCLLocationAccuracyBest;//最精确的定位

    self.locationManager.distanceFilter = kCLDistanceFilterNone; // 默认是kCLDistanceFilterNone，也可以设置其他值，表示用户移动的距离小于该范围内就不会接收到通知

    [self.locationManager startUpdatingLocation];

#pragma mark - GMSMapViewDelegate

//移动地图位置，重新定位

- (void)mapView:(GMSMapView*)mapViewdidTapAtCoordinate:(CLLocationCoordinate2D)coordinate{

    [self showLocation:coordinate];

}

//根据经纬度显示地图位置和大头针

-(void)showLocation:(CLLocationCoordinate2D)coordinate{

    __weak typeof(self) weakSelf =self;

    _currentCurCoordinate2D = coordinate;

    //地图显示在经纬度位置

       GMSCameraPosition*camera = [GMSCameraPosition cameraWithLatitude:coordinate.latitude longitude:coordinate.longitude zoom:14];

       self.mapView.camera= camera;

       //大头针显示经纬度位置  点击一次先清除上一次的大头针

       [self.marker.mapclear];

       self.marker.map=nil;

       self.marker= [GMSMarkermarkerWithPosition:coordinate];

       self.marker.map = self.mapView;

三、搜索地址

GMSAutocompleteViewController *acController = [[GMSAutocompleteViewController alloc] init];

    acController.delegate=self;

    [selfpresentViewController:acController animated:YES completion:nil];

#pragma mark - GMSAutocompleteViewControllerDelegate

// 用户选择搜索中的某个地址后返回的结果回调方法

- (void)viewController:(GMSAutocompleteViewController *)viewController

didAutocompleteWithPlace:(GMSPlace *)place {

[self dismissViewControllerAnimated:YES completion:nil];

[self.marker.map clear];

 self.marker.map=nil;

    // 通过location 或得到当前位置的经纬度

    GMSCameraPosition*camera = [GMSCameraPosition cameraWithLatitude:place.coordinate.latitude longitude:place.coordinate.longitude zoom:14];

    CLLocationCoordinate2D position2D =CLLocationCoordinate2DMake (place.coordinate.latitude, place.coordinate.longitude);

 self.marker= [GMSMarker markerWithPosition:position2D];

 self.mapView.camera= camera;

 self.marker.map = self.mapView;

    _currentCurCoordinate2D = position2D;

 self.addressLb.text= [NSString stringWithFormat:@"%@",place.name];

}
