How to resize image?

Question

I took the image from UIImagePickerController, but the file looks too large to be portable over the Internet, I would like to resize the image. I could not find any method related to the image process.

Any recommendation?

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