iOS开发之-百度地图定位-大头针

最近在做项目中,需要用到最新版的百度地图,这里是个小的Demo,希望能够有用到的。

效果图:先贴上。


iOS开发之-百度地图定位-大头针_第1张图片

一、直接到百度地图的API官网,自己搭建项目的百度API。手动添加即可。

二、在添加好百度API后,进行相应的配置。

AppDelegate中进行添加:

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions {

// Override point for customization after application launch.

//要使用百度地图,请先启动BaiduMapManager

_mapManager= [[BMKMapManageralloc]init];

/**

*百度地图SDK所有接口均支持百度坐标(BD09)和国测局坐标(GCJ02),用此方法设置您使用的坐标类型.

*默认是BD09(BMK_COORDTYPE_BD09LL)坐标.

*如果需要使用GCJ02坐标,需要设置CoordinateType为:BMK_COORDTYPE_COMMON.

*/

if([BMKMapManagersetCoordinateTypeUsedInBaiduMapSDK:BMK_COORDTYPE_COMMON]) {

NSLog(@"经纬度类型设置成功");

}else{

NSLog(@"经纬度类型设置失败");

}

BOOLret = [_mapManagerstart:@"你自己的API_Key"generalDelegate:self];

if(!ret) {

NSLog(@"manager start failed!");

}

returnYES;

}

三、进行直接上手即可。

注意:要在用到百度地图的地方,进行释放dealloc。。。
