百度地图使用、调起本机App地图

集成百度地图过程不做讲解，直接按照官方文档一步步走即可开发指南

引入头文件

#import <MapKit/MapKit.h>

#import <BaiduMapAPI_Base/BMKBaseComponent.h>//引入base相关所有的头文件
#import <BaiduMapAPI_Map/BMKMapComponent.h>//引入地图功能所有的头文件
#import <BaiduMapAPI_Map/BMKMapView.h>//只引入所需的单个头文件
#import <BaiduMapAPI_Location/BMKLocationComponent.h>//引入定位功能所有的头文件

创建地图和定位功能

    //进入普通定位态
    self.locService = [[BMKLocationService alloc]init];
    [self.locService startUserLocationService];

//    定位的精读 例如100米的位置 以内就算定位出你的位置 值越小越耗电
//    self.locService.desiredAccuracy = 100;
//    设置当超过设定距离的时候 开启定位
    self.locService.distanceFilter = 100;
    self.mapView.showsUserLocation = NO;//先关闭显示的定位图层
    self.mapView.userTrackingMode = BMKUserTrackingModeFollow;//设置定位的状态
    self.mapView.showsUserLocation = YES;//显示定位图
//    标准地图
    self.mapView.mapType = BMKMapTypeStandard;
//    地图比例尺级别，在手机上当前可使用的级别为4-21级
    self.mapView.zoomLevel = 16.0;
    //设定地图View能否支持旋转 只有旋转地图才会出现指南针 不知道为什么
    self.mapView.rotateEnabled = NO;
    self.mapView.compassPosition = CGPointMake(20,20);

//    self.mapView.mapPadding = UIEdgeInsetsMake(20, 20, 0, 0);
//    26.108768, 119.30714
//    CLLocationCoordinate2D coordinate = CLLocationCoordinate2DMake(26.108768, 119.30714);
//    BMKCoordinateRegion region ;//表示范围的结构体
//    region.center = coordinate;//中心点
//    region.span.latitudeDelta = 0.038325;//经度范围（设置为0.1表示显示范围为0.2的纬度范围）
//    region.span.longitudeDelta = 0.028045;//纬度范围
//////    设置显示区域 中心点和范围
//    [self.mapView setRegion:region animated:YES];
    //这只是限制了地图大小
//    [self.mapView setLimitMapRegion:region];

    
    //自定义精度圈
    BMKLocationViewDisplayParam *param = [[BMKLocationViewDisplayParam alloc] init];
    // 精度圈 边框颜色
    param.accuracyCircleStrokeColor = [UIColor colorWithRed:119/255.0 green:181/255.0 blue:254/255.0 alpha:0.6/1.0];
   ///精度圈 填充颜色
    param.accuracyCircleFillColor = [UIColor colorWithRed:119/255.0 green:181/255. blue:254/255.0 alpha:0.2];
    param.locationViewOffsetY = 0;//偏移量
    param.locationViewOffsetX = 0;
    param.locationViewImgName = @"icon_center_point";
    [self.mapView updateLocationViewWithParam:param];

创建代理销毁

-(void)viewWillAppear:(BOOL)animated
{
    [self.mapView viewWillAppear];
    self.mapView.delegate = self; // 此处记得不用的时候需要置nil，否则影响内存的释放
    self.locService.delegate = self;
}

-(void)viewWillDisappear:(BOOL)animated
{
    [self.mapView viewWillDisappear];
    self.mapView.delegate = nil; // 不用时，置nil
    self.locService.delegate = nil;
    [self.locService stopUserLocationService];//关闭定位服务
}

代理实现

#pragma mark  BMKLocationServiceDelegate
/**
 *在地图View将要启动定位时，会调用此函数
 *@param mapView 地图View
 */
- (void)willStartLocatingUser
{
    NSLog(@"start locate");
}


/**
 *用户方向更新后，会调用此函数
 *@param userLocation 新的用户位置
 */
- (void)didUpdateUserHeading:(BMKUserLocation *)userLocation
{
//    动态更新我的位置数据
    [self.mapView updateLocationData:userLocation];
    NSLog(@"heading is %@",userLocation.heading);
}
/**
 *用户位置更新后，会调用此函数  当前位置经纬度
 *@param userLocation 新的用户位置
 */
- (void)didUpdateBMKUserLocation:(BMKUserLocation *)userLocation
{
    
    NSLog(@"didUpdateUserLocation lat %f,long %f",userLocation.location.coordinate.latitude,userLocation.location.coordinate.longitude);
    [self.mapView updateLocationData:userLocation];
   
}


/**
 *在地图View停止定位后，会调用此函数
 *@param mapView 地图View
 */
- (void)didStopLocatingUser
{
    NSLog(@"stop locate");
}
/**
 *定位失败后，会调用此函数
 *@param mapView 地图View
 *@param error 错误号，参考CLError.h中定义的错误号
 */
- (void)didFailToLocateUserWithError:(NSError *)error
{
    NSLog(@"location error");
}

自定义大头针


-(void)viewDidAppear:(BOOL)animated{
    
#pragma mark 创建大头针
    //目的地
    BMKPointAnnotation* annotation = [[BMKPointAnnotation alloc]init];
    annotation.coordinate = CLLocationCoordinate2DMake(26.108768, 119.30714);
    annotation.title = @"这里是屏东城啊啊";
//  向地图窗口添加标注，需要实现BMKMapViewDelegate的-mapView:viewForAnnotation:函数来生成标注对应的View
    [self.mapView addAnnotation:annotation];
    self.pointAnnotation = annotation;
}

实现

#pragma mark  BMKMapViewDelegate
/**
 *根据anntation生成对应的View
 *@param mapView 地图View
 *@param annotation 指定的标注
 *@return 生成的标注View
 */
- (BMKAnnotationView *)mapView:(BMKMapView *)mapView viewForAnnotation:(id <BMKAnnotation>)annotation{
    
    if ([annotation isKindOfClass:[BMKPointAnnotation class]]){
        
        //缓存机制
        static NSString *reuseIndetifier = @"annotationReuseIndetifier";
        
        BMKPinAnnotationView *annotationView = (BMKPinAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:reuseIndetifier];
        if (annotationView == nil){
            annotationView = [[BMKPinAnnotationView alloc] initWithAnnotation:annotation
                                                reuseIdentifier:reuseIndetifier];
        }

        //自定义大头针图片
        annotationView.image = [UIImage imageNamed:@"地图上的点"];
        //选中该大头针 目的是一进来就默认选中 显示泡泡
        [annotationView setSelected:YES animated:YES];
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3.f * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            //取消指定的标注的选中状态，取消选中该annotation就会隐藏起泡泡
            for (id <BMKAnnotation> annotation in self.mapView.annotations) {
                
                if ([annotation isKindOfClass:[self.pointAnnotation class]]) {
                     [self.mapView deselectAnnotation:annotation animated:NO];
                }
            }
        });
        //自定义泡泡样式
//        annotationView.paopaoView = [[BMKActionPaopaoView alloc] initWithCustomView:@"自定义泡泡样式类"];
        
//        [self.mapView mapForceRefresh];
        return annotationView;
    }
        return nil;
}

调起本机地图app

首先在 info.plist 里添加白名单, 否则无法正常跳转
