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。
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。。。
