Get image location from iOS UIImagePickerController

I am try to develop iOS app which get the location of the Photo using UIImagePickerController and display it I am deploying it on iOS 7 device Here is what i did .

- (IBAction)takePhoto:(id)sender
{
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
    picker.showsCameraControls = YES;

    [self presentViewController:picker animated:YES
                     completion:^ {
//                         [picker takePicture];
                     }];}




-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    NSLog(@"Media Info: %@", info);

    NSString *mediaType = [info valueForKey:UIImagePickerControllerMediaType];



    ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
    {
        // Get the location property from the asset


        CLLocation *location = [myasset valueForProperty:ALAssetPropertyLocation];
        // I found that the easiest way is to send the location to another method

        latitude =location.coordinate.latitude; //[[gpsdata valueForKey:@"Latitude"]floatValue];
        longitutde =location.coordinate.longitude;

       NSString * strLocation=[NSString stringWithFormat:@"La:%f Lo%f",latitude,longitutde];



    };
    // This block will handle errors:
    ALAssetsLibraryAccessFailureBlock failureblock  = ^(NSError *myerror)
    {
        NSLog(@"Can not get asset - %@",[myerror localizedDescription]);
        // Do something to handle the error
    };








    if([mediaType isEqualToString:(NSString*)kUTTypeImage]) {
        UIImage *photoTaken = [info objectForKey:@"UIImagePickerControllerOriginalImage"];

        //Save Photo to library only if it wasnt already saved i.e. its just been taken
        if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
            UIImageWriteToSavedPhotosAlbum(photoTaken, self, @selector(image:didFinishSavingWithError:contextInfo:), nil);
        }


    }

    [picker dismissModalViewControllerAnimated:YES];
}

- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
    UIAlertView *alert;
    //NSLog(@"Image:%@", image);
    if (error) {
        alert = [[UIAlertView alloc] initWithTitle:@"Error!"
                                           message:[error localizedDescription]
                                          delegate:nil
                                 cancelButtonTitle:@"OK"
                                 otherButtonTitles:nil];
        [alert show];
    }

Location Services Should be enabled when the photo was taken.Try same code by enabling location services.

in the delegate implementation you can use the path of the image or the image itself:

// This method is called when an image has been chosen from the library or taken from the camera.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//You can retrieve the actual UIImage
    UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
//Or you can get the image url from AssetsLibrary
    NSURL *path = [info valueForKey:UIImagePickerControllerReferenceURL];
    [picker dismissViewControllerAnimated:YES completion:^{
    }];
}
