Create a MFMailComposeViewControllerand call addAttachmentData:mimeType:fileName:. The data will be the PDF you created. The mimeType will be application/pdf. And the fileName will be the name of the file in the email attachment. The code might look like something below:
创建一个MFMailComposeViewController并调用addAttachmentData:mimeType:fileName:. 数据将是您创建的 PDF。mimeType 将为application/pdf. fileName 将是电子邮件附件中文件的名称。代码可能如下所示：
From the tutorial you'll need to render your PDF into a NSMutableData object:
从教程中，您需要将 PDF 渲染为 NSMutableData 对象：
NSMutableData *pdfData = [NSMutableData data];
UIGraphicsBeginPDFContextToData(pdfData, bounds, nil);
Then at some point in the future you'll need to pass that pdfData to the MFMailComposeViewController.
然后在将来的某个时候，您需要将该 pdfData 传递给MFMailComposeViewController.
MFMailComposeViewController *vc = [[[MFMailComposeViewController alloc] init] autorelease];
[vc setSubject:@"my pdf"];
[vc addAttachmentData:pdfData mimeType:@"application/pdf" fileName:@"SomeFile.pdf"];
