1. 注冊(cè)應(yīng)用獲取key
2. 集成SDK

pod 'GoogleMaps'#地圖

3. 在VC中添加地圖視圖:GMSMapView

//谷歌地圖
#import <GoogleMaps/GoogleMaps.h>
@property (nonatomic,strong) GMSMapView *gmMapView;
-(GMSMapView *)gmMapView{
    if (_gmMapView == nil) {
        CGFloat latitude = 0.0f;
        CGFloat longitude = 0.0f;
        CLLocation *location = [[CLLocation alloc] initWithLatitude: latitude longitude: longitude];
        /**
         *設(shè)置顯示區(qū)域
         *location.coordinate位置信息
         *zoom精度
         */
        GMSCameraPosition *camera = [GMSCameraPosition cameraWithTarget:location.coordinate zoom:15];
        _gmMapView = [GMSMapView mapWithFrame:CGRectMake(0,0 ,SCREEN_WIDTH,SCREEN_HEIGHT-64) camera:camera];
    }
    return _gmMapView;
}

注意：在谷歌地圖中使用的坐標(biāo)系區(qū)分地域：
在國(guó)外是地球坐標(biāo)系:WGS84，在國(guó)內(nèi)是火星坐標(biāo)GCJ－02。關(guān)于坐標(biāo)

4. 添加自定義地標(biāo):GMSMarker

        //初始化
        GMSMarker *benginMarker = [[GMSMarker alloc] init];
        //位置
        benginMarker.position = ...;
        //標(biāo)題
        benginMarker.title = @"";
        //詳細(xì)
        benginMarker.snippet = @"";
        //圖標(biāo)
        benginMarker.icon = ...;
        //顯示
        benginMarker.map = self.gmMapView;

5. 添加軌跡:GMSPolyline、GMSMutablePath

    //初始化路線信息
    GMSMutablePath *path = [GMSMutablePath path];
    for (CLLocation *location in self.locations) {
        //添加路線上的點(diǎn)坐標(biāo)
        [path addCoordinate:location.coordinate];
    }
    //根據(jù)路線初始化一條軌跡
    GMSPolyline *polyline = [GMSPolyline polylineWithPath:path];
    //軌跡的寬度
    polyline.strokeWidth = 5.0;
    //軌跡顏色
    [polyline setStrokeColor:RGBA(81,191,179,1)];
    //添加軌跡
    polyline.map = self.gmMapView;
