            UIImage *image = [actualImage you want to resize];
            UIImage *tempImage = nil;
            CGSize targetSize = CGSizeMake(196,110);
            UIGraphicsBeginImageContext(targetSize);

            CGRect thumbnailRect = CGRectMake(0, 0, 0, 0);
            thumbnailRect.origin = CGPointMake(0.0,0.0);
            thumbnailRect.size.width  = targetSize.width;
            thumbnailRect.size.height = targetSize.height;

            [image drawInRect:thumbnailRect];

            tempImage = UIGraphicsGetImageFromCurrentImageContext();

            UIGraphicsEndImageContext();

You can use this tempImage , it will be resized Image

Hope, it helps !
