How to save the scaled image in iphone

Question

Thanks in advance. I used CGAffineTransformMakeScale(-1.0, 1.0) tranform on an image
And i got the image like this.

I am displaying that in an imageview.

Now, if i try to access that image and display in another imageview it is displaying normally like first image.

But i want the scaled image to access. Can any one help me how to save and get the scaled image. Here this CGAffineTransformMakeScale(-1.0, 1.0) method will not effect on image.

Answer 1

The following method helps to scale as well as flip the image

UIImage *newImage = [UIImage imageWithCGImage:oldImage.CGImage scale:1.0 orientation: UIImageOrientationUpMirrored];
