在这里就不在介绍百度的具体配置，配置详见http://developer.baidu.com/map/index.php?title=iossdk
1.首先接受基本的地图功能
新建一个地图类，xib拖也行，我这边是代码实现的。
_mapView = [[BMKMapView alloc]initWithFrame:CGRectMake(0, 0,self.view.frame.size.width, self.view.frame.size.height)];
[self.view addSubview:_mapView];
#pragma mark - 设置mapView属性
-(void)setMapViewProperty
{
_mapView.mapType = BMKUserTrackingModeFollowWithHeading;
_mapView.showsUserLocation = YES;
_mapView.zoomLevel = 16;
_mapView.rotateEnabled = NO;
[self passLocationValue];
}
#pragma mark -传入定位坐标 （必须打开程序时已经获取到地理位置坐标，为了解决地图定位时总是先显示天安门）
-(void)passLocationValue
{
BMKCoordinateRegion viewRegion = BMKCoordinateRegionMake([UserLocationManager sharedInstance].clloction.coordinate, BMKCoordinateSpanMake(0.02f,0.02f));
BMKCoordinateRegion adjustedRegion = [_mapView regionThatFits:viewRegion];
[_mapView setRegion:adjustedRegion animated:YES];
}
#pragma mark -设置定位圆点属性
-(void)setUserImage
{
BMKLocationViewDisplayParam* param = [[BMKLocationViewDisplayParam alloc] init];
param.locationViewOffsetY = 0;
param.locationViewOffsetX = 0;
param.isAccuracyCircleShow =NO;
param.isRotateAngleValid = NO;
[_mapView updateLocationViewWithParam:param];
}
实现BMKMapViewDelegate,以下是mapView的一些协议方法
**
*地图区域即将改变时会调用此接口
*@param mapview 地图View
*@param animated 是否动画
*/
- (void)mapView:(BMKMapView *)mapView regionWillChangeAnimated:(BOOL)animated
{
//TODO
}
/**
*地图区域改变完成后会调用此接口
*@param mapview 地图View
*@param animated 是否动画
*/
- (void)mapView:(BMKMapView *)mapView regionDidChangeAnimated:(BOOL)animated
{
//TODO
}
/**
*地图状态改变完成后会调用此接口
*@param mapview 地图View
*/
- (void)mapStatusDidChanged:(BMKMapView *)mapView
{
//TODO
}
这样基本的地图界面就出来了
2.地图定位
我这边是将定位封装了一个独立的manager类来管理定位和地图上滑动到的位置
#import "UserLocationManager.h"
#import "BMKGeocodeSearch.h"
@implementation UserLocationManager
+ (UserLocationManager *)sharedInstance
{
static UserLocationManager *_instance = nil;
@synchronized (self) {
if (_instance == nil) {
_instance = [[self alloc] init];
}
}
return _instance;
}
-(id)init
{
if (self == [super init])
{
//[self getBMKUserLocation];
//[self initGeoCodeSearch];
}
return self;
}
#pragma 初始化百度地图用户位置管理类
/**
* 初始化百度地图用户位置管理类
*/
- (void)initBMKUserLocation;
{
_locService = [[BMKLocationService alloc]init];
_locService.delegate = self;
[self startLocation];
}
#pragma 打开定位服务
/**
* 打开定位服务
*/
-(void)startLocation
{
[_locService startUserLocationService];
}
#pragma 关闭定位服务
/**
* 关闭定位服务
*/
-(void)stopLocation
{
[_locService stopUserLocationService];
}
#pragma BMKLocationServiceDelegate
/**
*用户位置更新后，会调用此函数
*@param userLocation 新的用户位置
*/
- (void)didUpdateUserLocation:(BMKUserLocation *)userLocation
{
cllocation = userLocation.location;
_clloction = cllocation;
_userLatitude = cllocation.coordinate.latitude;
_userLongitude = cllocation.coordinate.longitude;
[self stopLocation];
[self initGeoCodeSearch];
}
/**
*在停止定位后，会调用此函数
*/
- (void)didStopLocatingUser
{
[_mapViewVC setMapViewProperty];
}
/**
*定位失败后，会调用此函数
*@param error 错误号
*/
- (void)didFailToLocateUserWithError:(NSError *)error
{
[self stopLocation];
}
#pragma BMKGeoCodeSearchDelegate
-(void)initGeoCodeSearch
{
_geoCodeSearch = [[BMKGeoCodeSearch alloc]init];
_geoCodeSearch.delegate = self;
BMKReverseGeoCodeOption *reverseGeoCodeOption= [[BMKReverseGeoCodeOption alloc] init];
reverseGeoCodeOption.reverseGeoPoint = cllocation.coordinate;
[_geoCodeSearch reverseGeoCode:reverseGeoCodeOption];
}
/**
*返回反地理编码搜索结果
*@param searcher 搜索对象
*@param result 搜索结果
*@param error 错误号，@see BMKSearchErrorCode
*/
-(void) onGetReverseGeoCodeResult:(BMKGeoCodeSearch *)searcher result:(BMKReverseGeoCodeResult *)result errorCode:(BMKSearchErrorCode)error
{
if (error == 0)
{
_cityName = result.addressDetail.city;
NSLog(@"%@",_cityName);
}
}
@end
后续继续更新
