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", titude, currLocation.coordinate.longitude, currLocation.altitude);
jingduStr =[NSStringstringWithFormat:@"%f", titude];
weiduStr =[NSStringstringWithFormat:@"%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 ([errorcode] == kCLErrorLocationUnknown) {
//无法获取位置信息
}
}
