Answer 1

- (void)savePhoto
{
    UIImageWriteToSavedPhotosAlbum(((IndicatorImageView *)[self.imageViews objectAtIndex:_selectedImage]).image, nil, nil, nil);
}

If your array self._imageViews contain imageViews , why you try to access _imageViewagain??

also , Is _imageViews a property? use self.imageViews is better.

Answer 2

Here is the code you need. You need to pick the imageview.image.....not the actual image variable.

- (IBAction)saveImageButton:(id)sender {
UIImageWriteToSavedPhotosAlbum(_processedImageView.image, nil, nil, nil);
}

Answer 3

UIImageWriteToSavedPhotosAlbum(YOUR_IMAGE(UIImage), self, @selector(finishUIImageWriteToSavedPhotosAlbum:didFinishSavingWithError:contextInfo:), nil);
