How to resize an image?

Question

I have taken an image from UIImagePickerController, but the file looks too big to be transferred through internet, I'd like to resize the image. I couldn't find any method related to the image process.

Any recommendation?

Answer 1

You could create a context of the desired size using UIGraphicsBeginImageContext(), then draw the image to the context using UIImage's -drawInRect: method, and finally use UIGraphicsGetImageFromCurrentImageContext() to pull a new UIImage back out.
