百度地图SDK学习——2.0 基本内容显示

这次写的是，对于百度地图显示内容的基本认识。基本就是按照官方文档学习的，话不多说，开始看代码。

  本文是根据1.0内容接着写的

布局

布局

地图类型

类型有三种

BMKMapTypeNone = 0, ///< 空白地图
BMKMapTypeStandard = 1, ///< 标准地图
BMKMapTypeSatellite = 2, ///< 卫星地图

空白地图

空白地图

标准地图（默认）

默认地图

卫星地图

卫星地图

• 调用的方法是

当前地图类型，可设定为标准地图、卫星地图

@property (nonatomic) BMKMapType mapType;

_mapView.mapType = 地图类型;

交通状况

打开交通状况

打开交通状况

关闭交通状况

关闭交通状况

调用的方法

设定地图是否打开路况图层

@property(nonatomic, getter=isTrafficEnabled) BOOL trafficEnabled;

[_mapView setTrafficEnabled:YES/NO];

城市热力图

打开热力图

打开热力图

关闭热力图

关闭热力图

调用的方法

设定地图是否打开百度城市热力图图层（百度自有数据）,注：地图层级大于11时，可显示热力图

@property(nonatomic, getter=isBaiduHeatMapEnabled) BOOL baiduHeatMapEnabled;

[_mapView setBaiduHeatMapEnabled:YES/NO];
