本篇文章給大家分享的是有關怎么在iOS中實現(xiàn)百度地圖定位簽到功能,小編覺得挺實用的,因此分享給大家學習,希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。

一、在APPdelegate.m文件中引入:
#import#import
加入功能代碼:
#pragma mark 百度地圖設置 - (void)configBaiduMap { NSString *ak = @"xxxx"; BMKMapManager *mapManager = [[BMKMapManager alloc] init]; self.mapManager = mapManager; BOOL ret = [mapManager start:ak generalDelegate:nil]; [[BMKLocationAuth sharedInstance] checkPermisionWithKey:ak authDelegate:self]; if (!ret) { NSLog(@"manager start failed!"); } }
二、在用到地圖定位功能的viewController中
#import#import //引入base相關所有的頭文件 #import //引入地圖功能所有的頭文件
遵循協(xié)議
聲明全局變量
@property (nonatomic, strong) BMKUserLocation *userLocation; //當前位置對象 @property (nonatomic, strong) BMKLocationManager *locationManager;/** locationManager*/ @property (nonatomic, strong) BMKMapView *mapView;/** 百度地圖*/ //@property (nonatomic, strong) BMKPointAnnotation* annotation ;/** 標記*/ @property (nonatomic, strong) NSMutableArray *annotationArr;/** 標記數(shù)組*/ @property (nonatomic, strong) NSMutableArray *circleArr;/** 圓形數(shù)組*/
地圖SDK文檔中建議在以下代碼中如此設置, 目的是控制內存
- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [_mapView viewWillAppear]; _mapView.delegate = self; } - (void)viewWillDisappear:(BOOL)animated { [super viewWillDisappear:animated]; [_mapView viewWillDisappear]; _mapView.delegate = nil; } - (void)dealloc { if (_mapView) { _mapView = nil; } }
初始化數(shù)組,這兩個數(shù)組在接下來會用到
- (NSMutableArray *)annotationArr { if (!_annotationArr) { _annotationArr = [NSMutableArray array]; } return _annotationArr; } - (NSMutableArray *)circleArr { if (!_circleArr) { _circleArr = [NSMutableArray array]; } return _circleArr; }
添加地圖view
#pragma mark 添加地圖 - (void)addSignMapBgView { if (!self.mapBgView) { UIView *mapBgView = [UIView new]; self.mapBgView = mapBgView; mapBgView.backgroundColor = [CommUtls colorWithHexString:APP_BgColor]; [self addSubview:mapBgView]; [mapBgView makeConstraints:^(MASConstraintMaker *make) { make.top.equalTo(self.tipView.bottom); make.left.right.bottom.equalTo(0); }]; _mapView = [[BMKMapView alloc] initWithFrame:CGRectZero]; // _mapView.delegate = self; [_mapView setZoomLevel:21];//精確到5米 _mapView.showsUserLocation = YES;//顯示定位圖層 [mapBgView addSubview:_mapView]; [_mapView makeConstraints:^(MASConstraintMaker *make) { make.edges.equalTo(0); }]; _mapView.userTrackingMode = BMKUserTrackingModeNone; } }
初始化地圖定位:這里我用的是一次定位而沒有選擇持續(xù)定位。
#pragma mark 初始化locationManager - (void)initUserLocationManager { //因為mapView是在一個分離出來的view中創(chuàng)建的,所以在這里將signSetTypeView中的mapView賦給當前viewcontroller的mapView; self.mapView = self.mainView.signSetTypeView.mapView; self.mapView.delegate = self; // self.annotation = [[BMKPointAnnotation alloc] init]; // self.mapView是BMKMapView對象 //精度圈設置 BMKLocationViewDisplayParam *param = [[BMKLocationViewDisplayParam alloc] init]; //設置顯示精度圈,默認YES param.isAccuracyCircleShow = YES; //精度圈 邊框顏色 param.accuracyCircleStrokeColor = [UIColor colorWithRed:242/255.0 green:129/255.0 blue:126/255.0 alpha:1]; //精度圈 填充顏色 param.accuracyCircleFillColor = [UIColor colorWithRed:242/255.0 green:129/255.0 blue:126/255.0 alpha:0.3]; [self.mapView updateLocationViewWithParam:param]; self.userLocation = [[BMKUserLocation alloc] init]; //初始化實例 _locationManager = [[BMKLocationManager alloc] init]; //設置delegate _locationManager.delegate = self; //設置返回位置的坐標系類型 _locationManager.coordinateType = BMKLocationCoordinateTypeBMK09LL; //設置距離過濾參數(shù) _locationManager.distanceFilter = kCLDistanceFilterNone; //設置預期精度參數(shù) _locationManager.desiredAccuracy = kCLLocationAccuracyBest; //設置應用位置類型 _locationManager.activityType = CLActivityTypeAutomotiveNavigation; //設置是否自動停止位置更新 _locationManager.pausesLocationUpdatesAutomatically = NO; //設置是否允許后臺定位 //_locationManager.allowsBackgroundLocationUpdates = YES; //設置位置獲取超時時間 _locationManager.locationTimeout = 15; //設置獲取地址信息超時時間 _locationManager.reGeocodeTimeout = 15; //請求一次定位 [self requestLocation]; }
請求定位,獲取經(jīng)緯度
#pragma mark 請求定位 - (void)requestLocation { [_locationManager requestLocationWithReGeocode:YES withNetworkState:YES completionBlock:^(BMKLocation * _Nullable location, BMKLocationNetworkState state, NSError * _Nullable error) { if (error) { NSLog(@"locError:{%ld - %@};", (long)error.code, error.localizedDescription); } if (location) {//得到定位信息,添加annotation if (location.location) { NSLog(@"LOC = %@",location.location); } if (location.rgcData) { NSLog(@"rgc = %@",[location.rgcData description]); } if (!location) { return; } if (!self.userLocation) { self.userLocation = [[BMKUserLocation alloc] init]; } self.userLocation.location = location.location; [self.mapView updateLocationData:self.userLocation]; CLLocationCoordinate2D mycoordinate = location.location.coordinate; self.mapView.centerCoordinate = mycoordinate; //賦予初始值 self.viewModel.lat = [NSString stringWithFormat:@"%f", location.location.coordinate.latitude]; self.viewModel.lng = [NSString stringWithFormat:@"%f",location.location.coordinate.longitude]; self.viewModel.radius = @"50"; //打印經(jīng)緯度 NSLog(@"didUpdateUserLocation lat %f,long %f",location.location.coordinate.latitude,location.location.coordinate.longitude); } NSLog(@"netstate = %d",state); }]; }
地圖長按選點功能實現(xiàn):
//長按地圖選點 - (void)mapview:(BMKMapView *)mapView onLongClick:(CLLocationCoordinate2D)coordinate { if (self.annotationArr.count > 0) { [mapView removeAnnotations:self.annotationArr]; [self.annotationArr removeAllObjects]; BMKPointAnnotation *annotation = [[BMKPointAnnotation alloc]init]; annotation.coordinate = coordinate; [self.annotationArr addObject:annotation]; [mapView addAnnotations:self.annotationArr]; } else { BMKPointAnnotation *annotation = [[BMKPointAnnotation alloc]init]; annotation.coordinate = coordinate; [self.annotationArr addObject:annotation]; [mapView addAnnotations:self.annotationArr]; } //彈出半徑選擇框 [self showLocationSelectRadiusViewWithCoordinate:coordinate]; }
選點后彈出選擇定位范圍彈框
#pragma mark 彈出位置彈框 - (void)showLocationSelectRadiusViewWithCoordinate:(CLLocationCoordinate2D)coordinate { ExtraActLocationSignPopView *popView = [ExtraActLocationSignPopView new]; [popView show]; @weakify(self); [popView.locatioonSureSignal subscribeNext:^(NSString *x) { @strongify(self); self.viewModel.radius = x; CGFloat radius = [x floatValue]; [self circleWithCenterWithCoordinate2D:coordinate radius:radius]; }]; }
設置好定位點以及半徑范圍后繪制范圍圈,開始的時候聲明的circleArr在這里用來盛放添加的區(qū)域圓形,在添加新的圓圈的時候,將之前舊的移除,保證每次繪制的范圍都是最新的,同理annotationArr也是這個功能,因為API有提供的- (void)addOverlays:(NSArray *)overlays;這個方法:/** *向地圖窗口添加一組Overlay,需要實現(xiàn)BMKMapViewDelegate的-mapView:viewForOverlay:函數(shù)來生成標注對應的View *@param overlays 要添加的overlay數(shù)組 */
#pragma mark 添加區(qū)域圓形覆蓋 - (void)circleWithCenterWithCoordinate2D:(CLLocationCoordinate2D )coor radius:(CGFloat)radius { NSLog(@"coordinate lat %f,long %f",coor.latitude,coor.longitude); //賦予點擊選點值 self.viewModel.lat = [NSString stringWithFormat:@"%f", coor.latitude]; self.viewModel.lng = [NSString stringWithFormat:@"%f",coor.longitude]; if (self.circleArr.count > 0) { [_mapView removeOverlays:self.circleArr]; [self.circleArr removeAllObjects]; BMKCircle *circle = [BMKCircle circleWithCenterCoordinate:coor radius:radius]; [self.circleArr addObject:circle]; [_mapView addOverlays:self.circleArr]; } else { BMKCircle *circle = [BMKCircle circleWithCenterCoordinate:coor radius:radius]; [self.circleArr addObject:circle]; [_mapView addOverlays:self.circleArr]; } } #pragma mark 重繪overlay - (BMKOverlayView *)mapView:(BMKMapView *)mapView viewForOverlay:(id)overlay{ if ([overlay isKindOfClass:[BMKCircle class]]){ BMKCircleView* circleView = [[BMKCircleView alloc] initWithOverlay:overlay]; circleView.fillColor = [UIColor colorWithRed:33/255.0 green:196/255.0 blue:206/255.0 alpha:0.3]; circleView.strokeColor = [UIColor colorWithRed:33/255.0 green:196/255.0 blue:206/255.0 alpha:1]; circleView.lineWidth = 1.0; return circleView; } return nil; }
