First get your image in UIImage object. Create your size what ever you want and use following..

UIImage *image = // you image;
CGSize size;
if ([[UIScreen mainScreen] respondsToSelector:@selector(displayLinkWithTarget:selector:)] &&
([UIScreen mainScreen].scale == 2.0)) {

     // RETINA DISPLAY
      size = CGSizeMake(640, 640);
}
else {
     // Non Ratina device
      size = CGSizeMake(320, 320);
}

UIGraphicsBeginImageContext(size);
[image drawInRect:CGRectMake(0, 0, size.width, size.height)];
UIImage *destImage = UIGraphicsGetImageFromCurrentImageContext();    
UIGraphicsEndImageContext();

Now you will get destImage with new resolution.

Hope this is what you are looking for :)
