ios谷歌地图集成

1.开启api

https://console.cloud.google.com/google/maps-apis/api-list?project=charming-study-196505

2.设置APIkey

3.pod 安装sdk

pod 'GoogleMaps'
pod 'GooglePlaces'

4.注册服务

#import <GoogleMaps/GoogleMaps.h>
@import GooglePlaces;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    ...
    [GMSServices provideAPIKey:@"你的APIKEY1"];
    [GMSPlacesClient provideAPIKey:@"你的APIKEY2"];
     ....
    return YES;
}

5.初始化地图

    #pragma mark - 地图比例尺级别
    //1: World
//    5: Landmass/continent
//    10: City
//    15: Streets
//    20: Buildings
    float zoomLevel =  20;
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithLatitude:defaultLocation.latitude
                                                            longitude:defaultLocation.longitude
                                                                 zoom:zoomLevel];
    mapView = [GMSMapView mapWithFrame:self.view.bounds camera:camera];
    mapView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    
   
    #pragma mark - 地图类型
    [mapView setMapType:kGMSTypeNormal];//地图类型
    #pragma mark - 设置缩放级别限制
//    [mapView setMinZoom:10 maxZoom:15];
    //地图设置
    #pragma mark - 手势
//    mapView.settings.scrollGestures = NO;//平移地图
//    mapView.settings.zoomGestures = NO;//缩放地图
//    mapView.settings.tiltGestures = NO;//调整视角，俯视
//    mapView.settings.rotateGestures = NO;//旋转地图
    #pragma mark - 按钮展示
    mapView.settings.indoorPicker = NO;//楼层选择器按钮
    mapView.settings.myLocationButton = YES;//我的位置按钮
    mapView.settings.compassButton = YES;//指南针按钮
    #pragma mark - 图层展示
    mapView.myLocationEnabled = YES;//我的定位poi
//    mapView.trafficEnabled = YES;//交通层
    mapView.indoorEnabled = NO;//室内地图.
    #pragma mark - 地图内边距，控制内置组件不遮挡UI
//    mapView.padding = UIEdgeInsetsMake(10.0, 10.0, 10.0, 100.0);

    mapView.delegate = self;
    [self.view addSubview:mapView];

6.地面覆盖层

-(void)addGMSGroundOverlay{
    [mapView clear];
    CLLocationCoordinate2D southWest = CLLocationCoordinate2DMake(40.712216,-74.22655);
    CLLocationCoordinate2D northEast = CLLocationCoordinate2DMake(40.773941,-74.12544);
    GMSCameraPosition *ps = [[GMSCameraPosition alloc] initWithTarget:southWest zoom:18];
    [mapView setCamera:ps];
    GMSCoordinateBounds *overlayBounds = [[GMSCoordinateBounds alloc] initWithCoordinate:southWest
                                                                            coordinate:northEast];
    UIImage *icon = [UIImage imageNamed:@"1"];
    GMSGroundOverlay *overlay = [GMSGroundOverlay groundOverlayWithBounds:overlayBounds icon:icon];
    overlay.map = mapView;     
}

7.不规则形状图层

#pragma mark - 不规则点
-(void)addhollowPolygon{
    CLLocationCoordinate2D hydeParkLocation = CLLocationCoordinate2DMake(41.84415, -87.63186);
    GMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:hydeParkLocation
                                                               zoom:16];
    [mapView setCamera:camera];
//https://developers.google.com/maps/documentation/utilities/polylineutility 加密折线
    NSString *hydePark = @"{_r~FbkwuOyS~qIdmEzrBh~A_~Ada@i_DezAixHwvEhjB??";//外围圈折现
    NSString *archibaldFountain = @"e{o~Ffj~uOyCycBjm@zaC|^mE~F_mE??}fAnaAwKs{CrcCnc@qHbgH";//孔洞折现

    GMSPolygon *hollowPolygon = [[GMSPolygon alloc] init];
    hollowPolygon.path = [GMSPath pathFromEncodedPath:hydePark];
    hollowPolygon.holes = @[[GMSPath pathFromEncodedPath:archibaldFountain]];
    hollowPolygon.fillColor = [UIColor colorWithRed:1.0 green:0.0 blue:0.0 alpha:0.8];
    hollowPolygon.strokeColor = [UIColor colorWithRed:0.0 green:1.0 blue:0.0 alpha:1.0];
    hollowPolygon.strokeWidth = 2;
    hollowPolygon.map = mapView; 
}

8.画线

-(void)addGMSPolyline{
    [mapView clear];
    CLLocationCoordinate2D center = CLLocationCoordinate2DMake(-33.85, 151.20);
    GMSCameraPosition *ps = [[GMSCameraPosition alloc] initWithTarget:center zoom:14];
    [mapView setCamera:ps];
    GMSMutablePath *path = [GMSMutablePath path];
    [path addCoordinate:CLLocationCoordinate2DMake(-33.85, 151.20)];
    [path addCoordinate:CLLocationCoordinate2DMake(-33.70, 151.40)];
    [path addCoordinate:CLLocationCoordinate2DMake(-33.73, 151.41)];
    GMSPolyline *polyline = [GMSPolyline polylineWithPath:path];
    polyline.map = mapView;
}

9.画圆

image.png

#pragma mark - 画圆圈
-(void)addGMSCircle{
    [mapView clear];
    CLLocationCoordinate2D center = CLLocationCoordinate2DMake(37.35, -122.0);
    GMSCameraPosition *ps = [[GMSCameraPosition alloc] initWithTarget:center zoom:14];
    [mapView setCamera:ps];
    CLLocationCoordinate2D circleCenter = CLLocationCoordinate2DMake(37.35, -122.0);
    GMSCircle *circle = [GMSCircle circleWithPosition:circleCenter
                                             radius:1000];
    circle.fillColor = [UIColor colorWithRed:0.25 green:0 blue:0 alpha:0.05];
    circle.strokeColor = [UIColor redColor];
    circle.strokeWidth = 5;
    circle.map = mapView;
}

10.画矩形

#pragma mark - 画矩形
-(void)addGMSPolygonRect{
    [mapView clear];
    CLLocationCoordinate2D center = CLLocationCoordinate2DMake(37.36, -122.1);
    GMSCameraPosition *ps = [[GMSCameraPosition alloc] initWithTarget:center zoom:14];
    [mapView setCamera:ps];
    // Create a rectangular path
    GMSMutablePath *rect = [GMSMutablePath path];
    [rect addCoordinate:CLLocationCoordinate2DMake(37.36, -122.0)];
    [rect addCoordinate:CLLocationCoordinate2DMake(37.45, -122.0)];
    [rect addCoordinate:CLLocationCoordinate2DMake(37.45, -122.2)];
    [rect addCoordinate:CLLocationCoordinate2DMake(37.36, -122.2)];

    // Create the polygon, and assign it to the map.
    GMSPolygon *polygon = [GMSPolygon polygonWithPath:rect];
    polygon.fillColor = [UIColor colorWithRed:0.25 green:0 blue:0 alpha:0.05];
    polygon.strokeColor = [UIColor blackColor];
    polygon.strokeWidth = 2;
    polygon.map = mapView;
}

11.调用谷歌地图app导航

*开启跳转schemes注册
