All you can do is load the image file and draw it into a newly created PDF context:

1. Load the JPEG file into a UIImage.
2. Create a new PDF context with CGPDFContextCreate() or CGPDFContextCreateWithURL().
3. Add a page to the PDF context with CGPDFContextBeginPage().
4. Draw the image into the PDF context. You will probably have to play a bit with the coordinate systems and the size of the image, depending on how you want the image to appear in the PDF.
5. Call CGPDFContextEndPage() and CGPDFContextClose().
