Objective-C PDF渲染

Question

How can i reduce the size of PDF being rendered using [v.layer renderInContext:pdfContext]; Right now, I am rendering a 10 pages PDF with 20 images(2 of each page) and the size is 2.7mb. How can I reduce it to less than 2 mb?

Thanks!

from RR's comment, you can try to reduce a little quality of each image before doing the conversion to PDF. Like this:

lowResImage = [UIImage imageWithData:UIImageJPEGRepresentation(highResImage, quality)];

Make quality < 1.0 etc.
