blocks|key|4906589|text|有一个很棒的开源api，可以用来创建PDF。您可以向PDF添加文本、图像和页眉，然后发送PDF或将其保存到文件。Api位于http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI如果您对此有任何疑问，我们的支持非常棒，请联系maor.kern@mobice.org|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|4906590|entityMap|0|LINK|mutability|MUTABLE|url|http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI^0|1P|1I|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Theres a great open source api for creating PDFs. You can add text, images, and headers to the PDF, and then either send the PDF or save it to a file.
The Api is at <a href="http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI" rel="noreferrer">http://code.google.com/p/pdf-api-iphonesdk/wiki/PDFAPI</a>
If you have any questions about it, the support is great, just contact maor.kern@mobice.org

You can use UIKit to generate a pdf. Its really simple. You just have to start a pdf context and write out contents to it:
