UIImagePickerController for multiple buttons

I have 4 UIButtons and 4 UIImgeViews and each button should change image of its UIImageView using UIImagePickerController. Button #1 should change imageview #1 and so on. all should be different. It works fine with just the first button and imageview but I'm not sure how to apply it for all 4.

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{

UIImage *image1 = [info objectForKey:UIImagePickerControllerOriginalImage];


NSData *data = UIImagePNGRepresentation(image1);
NSString *myGrabbedImage = @"myGrabbedImage.png";
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path objectAtIndex:0];
NSString *fullPathToFile = [documentDirectory stringByAppendingPathComponent:myGrabbedImage];

[data writeToFile:fullPathToFile atomically:YES];
[[self firstImageView]setImage:image1];


[self dismissViewControllerAnimated:YES completion:nil];

}

I know this only sets a picture to the first imageView but how can I do it for all 4 ?

The button-pressed code can leave a value lying around to say which button is being dealt with:

- (void) buttonPressed:(id)sender {
      imageViewBeingEdited = sender.imageView;
      // display image picker here
}

then

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    imageViewBeingEdited.image = [info objectForKey:UIImagePickerControllerOriginalImage];
    ...
}
