公司提了新的需求，用百度地图定位检索周边，要求仿照微信的地理位置分享。我看了下，封装了几个工具类。实现效果如上图。
百度地理位置定位工具
百度地图API已经把定位功能和地图功能分开了。下面定位工具只需要导入定位API：

/**

@param block 返回

-(void)getAddressDetail:(void(^)(AddressModel *addressModel)) block;
//获取两个坐标间的距离
- (CGFloat)BMKPointToPointDistence:(CLLocationCoordinate2D)point1 point2:(CLLocationCoordinate2D)point2;

dispatch_once(&onceToken, ^{

[_instance locationManager];
});
return _instance;
}
+(instancetype) sharedInstance{
if (_instance == nil) {
_instance = [[super alloc]init];
}
return _instance;
}
- (BMKLocationManager *)locationManager{
if(!_locationManager){
[[BMKLocationAuth sharedInstance] checkPermisionWithKey:[MyAPPKeys getBaiDuKey] authDelegate:self];
//初始化实例
_locationManager = [[BMKLocationManager alloc] init];
//设置delegate
_locationManager.delegate = self;
//设置返回位置的坐标系类型
_locationManager.coordinateType = BMKLocationCoordinateTypeBMK09LL;
//设置距离过滤参数
_locationManager.distanceFilter = kCLDistanceFilterNone;
//设置预期精度参数
_locationManager.desiredAccuracy = kCLLocationAccuracyBest;
//设置应用位置类型
_locationManager.activityType = CLActivityTypeAutomotiveNavigation;
//设置是否自动停止位置更新
_locationManager.pausesLocationUpdatesAutomatically = NO;
//设置是否允许后台定位
_locationManager.allowsBackgroundLocationUpdates = NO;
//设置位置获取超时时间
_locationManager.locationTimeout = 10;
//设置获取地址信息超时时间
_locationManager.reGeocodeTimeout = 10;
}
return _locationManager;
}
//获取当前详细地址
-(void)getAddressDetail:(void(^)(AddressModel *addressModel)) block{
[self.locationManager requestLocationWithReGeocode:true withNetworkState:true completionBlock:^(BMKLocation * _Nullable location, BMKLocationNetworkState state, NSError * _Nullable error) {
AddressModel *moel = [[AddressModel alloc]init];
if (error) {
// SHOW_MSG([error.userInfo valueForKey:@"NSLocalizedDescription"]);
}else{
NSLog(@"location --- %@",location);
moel.latitude = location.location.coordinate.latitude;
moel.longitude = location.location.coordinate.longitude;
moel.province = location.rgcData.province;
moel.city = location.rgcData.city;
moel.district = location.rgcData.district;
moel.street = location.rgcData.street;
moel.streetNumber = location.rgcData.streetNumber;
moel.locationDescribe = location.rgcData.locationDescribe;
moel.userName = location.rgcData.locationDescribe;
}
block(moel);
}];
}
#pragma mark --BMKLocationAuthDelegate
//定位授权
- (void)onCheckPermissionState:(BMKLocationAuthErrorCode)iError{
if(iError == BMKLocationAuthErrorSuccess){
NSLog(@"定位授权成功");
}else{
NSLog(@"定位授权失败");
}
}
#pragma mark --BMKLocationManagerDelegate
//定位返回 ： 移动定位时 多次
-(void)BMKLocationManager:(BMKLocationManager *)manager didUpdateLocation:(BMKLocation *)location orError:(NSError *)error{
}
- (CGFloat)BMKPointToPointDistence:(CLLocationCoordinate2D)point1 point2:(CLLocationCoordinate2D)point2{
CLLocation *orig=[[CLLocation alloc] initWithLatitude:point1.latitude longitude:point1.longitude];
CLLocation* dist=[[CLLocation alloc] initWithLatitude:point2.latitude longitude:point2.longitude];
CLLocationDistance meters=[orig distanceFromLocation:dist];
NSLog(@"距离:%f",meters);
return meters;
}
@end
百度Poi检索服务Tool
百度Poi检索 分以自己为中心检索，以城市建设，还有一个是 地点输入提示检索（Sug检索，与Poi检索平行关系，但是为了方便，写到一个封装里了）
注意：Poi和sug检索需要关键词，没有关键词是检索不成功的
