iOS8 根据经纬度显示地名

我们很多时候做项目的时候都选用通过手机获取定位，然后传数据给后台，这是iOS8根据经纬度显示地名的demo

#pragma mark--实现CLLocationManagerDelegate的代理方法,获取地理位置（镔）===========================================================================

//(1)获取到位置数据，返回的是一个CLLocation的数组，一般使用其中的一个

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

{

    CLLocation *currLocation = [locations lastObject];

    NSLog(@"经度=%f 纬度=%f 高度=%f", currLocation.coordinate.latitude, currLocation.coordinate.longitude, currLocation.altitude);

    jingduStr =[NSString stringWithFormat:@"%f", currLocation.coordinate.latitude];

    weiduStr =[NSString stringWithFormat:@"%f", currLocation.coordinate.longitude];

    NSLog(@"jijijijijij:%@",jingduStr);

     [self change];

    }

//(2)获取用户位置数据失败的回调方法，在此通知用户

- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

{

    if ([error code] == kCLErrorDenied)

    {

        //访问被拒绝

    }

    if ([error code] == kCLErrorLocationUnknown) {

        //无法获取位置信息

    }

}
