// 如果要关注网络及授权验证事件，请设定 generalDelegate参数
BOOL ret = [_mapManager start:XSBaiduMapApiKey  generalDelegate:nil];
if (!ret) {
    XSLog(@"BMKMapManager start failed!");
}

2、初始化地图

3、显示自定义大头针

  • 3.1、从服务器获取当前设备的相关信息转为模型数据(XSDeviceLocation *locationDetails)

  • 3.2、根据当前显示的地图类型设置对应的坐标信息大头针

    • 我的做法在XSDeviceLocation模型里面提供了对应地图的获取属性，在属性getter方法中进行服务器的坐标转换(处理国内返回火星坐标、国外返回标准坐标)
    • 如获取百度坐标locationCoordinateBaidu、获取谷歌坐标locationCoordinateGoogle

    • 根据类型设置坐标数据

      - (void)setupPetLocationCoordinate:(CLLocationCoordinate2D)coordinate mapType:(XSDisplayMapType)mapType
      {
          // 坐标过滤等其他操作
          // ...
          [self setupBaiduMapCoordinate:coordinate];
      }

    {

        // 添加大头针模型数据
        self.pointAnnotation.annotationType = XSAnnotationTypeLocationPoint;
        self.pointAnnotation.locationDetailsModel = self.locationDetails;
        self.pointAnnotation.coordinate = coordinate;
        [self.baiduMapView addAnnotation:self.pointAnnotation];
        // 添加精度圈
        !self.baiduAccuracyCircle ? : [self.baiduMapView removeOverlay:self.baiduAccuracyCircle]; // 移除添加的精度圈
        if (self.locationDetails.GpsType == XSLocationModeWifiAndLbs || self.locationDetails.GpsType == XSLocationModeLbs) { // wifi 显示精度圈
            self.baiduAccuracyCircle = [BMKCircle circleWithCenterCoordinate:coordinate radius:self.locationDetails.Radius];
            [self.baiduMapView addOverlay:self.baiduAccuracyCircle];
        }
        // 解析地址
        BMKReverseGeoCodeOption *reverseGeocodeSearchOption = [[BMKReverseGeoCodeOption alloc] init];
        reverseGeocodeSearchOption.reverseGeoPoint = coordinate;
        if (![self.geoCodeSearch reverseGeoCode:reverseGeocodeSearchOption]) {
            XSLog(@"百度反地理编码获取地址失败");
        }
        // 计算地图区域缩放
        CLLocationDistance horizontalScreenDistance = [self horizontalScreenDistance];
        if (self.locationDetails.Radius * 2 < horizontalScreenDistance || self.baiduMapView.zoomLevel <= kMapsMinZoomLevel) {
            return;
        }
        BMKCoordinateRegion region = BMKCoordinateRegionMakeWithDistance(coordinate, self.locationDetails.Radius * 2 + self.locationDetails.Radius / 2, self.locationDetails.Radius * 2 + self.locationDetails.Radius / 2);
        [self.baiduMapView setRegion:region animated:YES];
    }

    • 自定义大头针模型XSPointAnnotation继承自BMKPointAnnotation

      • 扩充两个属性：
      • annotationType ：枚举，显示的大头针类型（切换图标）
      • locationDetailsModel ：当前大头针的模型数据，点击显示气泡详情的数据

    • 添加精度圈后精度半径过大可能超出屏幕影响用户体验，解决方法如下：

      • 根据屏幕最左和最后两个点，转换出地图上对应的坐标点并计算出距离d
      • 根据当前精度圈半径 * 2 和 d 比较，如果超出屏幕就重新设置地图显示区域

      • 计算屏幕距离核心代码

        5
        CLLocationCoordinate2D leftCoor = [self.baiduMapView convertPoint:CGPointMake(0, XSScreenH) toCoordinateFromView:self.view];
        CLLocationCoordinate2D rightCoor = [self.baiduMapView convertPoint:CGPointMake(XSScreenW, XSScreenH) toCoordinateFromView:self.view];
        BMKMapPoint pointLeft = BMKMapPointForCoordinate(leftCoor);
        BMKMapPoint pointRight = BMKMapPointForCoordinate(rightCoor);
        return BMKMetersBetweenMapPoints(pointLeft, pointRight);

  • 3.4、配置信息的回调（真正开始处理显示位置大头针、精度圈、点击显示的弹框泡泡）

4、多个坐标线显示在屏幕范围内

  • 绘制多个轨迹点和绘制线比较简单，直接参考官方文档
  • 在历史轨迹界面，可能希望显示的所有轨迹点都在屏幕范围内

4、多个坐标线显示在屏幕范围内

  • 绘制多个轨迹点和绘制线比较简单，直接参考官方文档
  • 在历史轨迹界面，可能希望显示的所有轨迹点都在屏幕范围内

Maps 导航

  • 检测是否安装对应的地图
  • 常用的4个地图的 URL Scheme:

    1.苹果自带地图（不需要检测，所以不需要URL Scheme）
    2.百度地图 ：baidumap://
    3.高德地图 ：iosamap://
    4.谷歌地图 ：comgooglemaps://

  • 在IOS9之后，苹果进一步完善了安全机制，必须在plist里面设置url scheme白名单，不然无法打开对应的应用
  • 添加白名单：

在 info.plist 文件里面，添加一个字段：LSApplicationQueriesSchemes，类型为数组

然后在这个数组里面再添加我们所需要的地图 URL Scheme :

  • 应用内部调用google maps地图发起导航功能

1、x-source=%@&x-success=%@跟高德一样 这里分别代表APP的名称和URL Scheme

2、saddr=这里留空则表示从当前位置触发。

  • 应用内部调用百度地图发起导航功能

1，origin=, 这个是不能被修改的，不然无法把出发位置设置为当前位置

2，destination = latlng:%f,%f|name = 目的地这里面的 name 的字段不能省略，否则导航会失败，而后面的文字则可以随意，赋个你的目的地的值给他就可以了。

3，coord_type = gcj02coord_type 允许的值为 bd09ll、gcj02、wgs84，如果你 APP 的地图 SDK 用的是百度地图 SDK，请填 bd09ll，否则就填gcj02，wgs84的话基本是用不上了

    baiduMapDic[@"url"] = urlString;
    [maps addObject:baiduMapDic];
}
  • 应用内部调用高德地图发起导航功能

1、sourceApplication=%@&backScheme=%@sourceApplication代表你自己APP的名称 会在之后跳回的时候显示出来 所以必须填写 backScheme是你APP的URL Scheme 不填是跳不回来的哟

2、dev=0这里填0就行了，跟上面的gcj02一个意思 1代表wgs84 也用不上
