地图轨迹

概述地图轨迹

下面是内存溢出 jb51.cc 通过网络收集整理的代码片段。

内存溢出小编现在分享给大家，也给大家做个参考。

.h    IBOutlet GMSMapVIEw *_mapVIEw;注： _mapVIEw我这里使用了Storyboard，放地图放在VIEw里面  就是以下三部分。- (voID)initMapVIEw{    //创建地图    [_mapVIEw clear];    GMSCameraposition *camera = [GMSCameraposition cameraWithLatitude:-6.13631                                                            longitude:106.789352                                                                 zoom:ZOOM_LEVEL];    _mapVIEw.mapType = kGMSTypenormal;    _mapVIEw.camera = camera;    _mapVIEw.delegate = self;    _geocoder = [[GMSGeocoder alloc] init];     polyline = [[GMSpolyline alloc] init];    linepath = [GMSMutablePath path];    CLLocationCoordinate2D coords;            coords.latitude = -6.136271;            coords.longitude = 106.789216;                         _mapVIEw.camera = [GMSCameraposition cameraWithTarget:coords                                                             zoom:ZOOM_LEVEL];                //显示标注        GMSReverseGeocodeCallback handler = ^(GMSReverseGeocodeResponse *response,NSError *error) {            if (response && response.firstResult) {                                 GMSMarker *marker = [[GMSMarker alloc] init];                marker.position = coords;                marker.Title = response.firstResult.addressline1;                marker.snippet = response.firstResult.addressline2;                _addressData = response.firstResult.addressline2;                [self refreshGpsInfo];                marker.appearanimation = kGMSMarkerAnimationNone;                marker.icon = SEtimage(@"deviceannotation.png");                marker.map = _mapVIEw;            } else {                NSLog(@"Could not reverse geocode point (%f,%f): %@",coords.latitude,coords.longitude,error);            }        };                 [_geocoder reverseGeocodeCoordinate:coords                          completionHandler:handler];     //画线，轨迹回放                [linepath removeAllCoordinates];                [self drawlineWithLocationArray:trackArray];  /*注，trackArray里面的数据格式    CLLocation *NowLocation = [[CLLocation alloc] initWithLatitude:coords.latitude longitude:coords.longitude];    [trackArray addobject:NowLocation]; */  ｝   //画线，使用轨迹回放  - (voID)drawlineWithLocationArray:(NSArray *)locationArray{         if(current_type == _CURRENT_TRACK)        polyline.strokecolor = [UIcolor bluecolor];    else        polyline.strokecolor = [UIcolor redcolor];    polyline.strokeWIDth = 6.f;         // for(int IDx = 0; IDx < pointStrings.count; IDx++)    for(int IDx = 0; IDx < locationArray.count; IDx++)    {        CLLocation *location = [locationArray objectAtIndex:IDx];        CLLocationdegrees latitude  = location.coordinate.latitude;        CLLocationdegrees longitude = location.coordinate.longitude;                 // create our coordinate and add it to the correct spot in the array        CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(latitude,longitude);        [linepath addCoordinate:coordinate];    }    polyline.path = linepath;    polyline.map = _mapVIEw;}
