Issues with email attachment, PDF and CSV

Question

I'm working with PDF generation,it generated the PDF, viewed using QLPreviewController, all worked fine except mail forwarding, I have two attachments of type .pdf and .csv. I have the following issues while emailing.

sometimes no attachments while emailing
pdf size will be very huge when pdf contains image(10 mb for one page pdf, if it contains image)

Problem is when testing in device,in simulator it all works fine..., I come to know some exporting or importing UTI associated issues here since I am a starter I feel difficult to understand it, I think some UTI's I have to add somewhere.. Can anyone please help me to identify the issue and solve, please. Thanks in advance.

Well my only guess is that the PDF is rasterizing the whole area as an image and taking up a huge amount of space, you will have to construct the PDF in a different way. — Grady Player, Mar 05 '13 at 05:27
@GradyPlayer thanks.. but my bigger issue is number one, which is not solved. And size is ok if there is no image added to pdf. — Mumthezir VP, Mar 05 '13 at 05:32
Post an example of what you are doing... The encoding is typically base64 — Grady Player, Mar 06 '13 at 14:46

1. Attachment issue

set mime type as text/csv instead of application/csv or image/csv. code is as shown below

[mailComposer addAttachmentData:[NSData dataWithContentsOfFile:self.csvFilePath]
                               mimeType:@"text/csv" fileName:[NSString stringWithFormat:@"csvPage.csv" ]];

1. Size issue

I struggled a lot.. at last when wrote image in jpeg format to pdf page using below code, size got reduced ten times!!

UIImage *lowResImage = [UIImage imageWithData:UIImageJPEGRepresentation(plotImage, 0.02)];
