    NSMutableData *pdfData =[NSMutableData dataWithContentsOfFile:filePath];

    [picker addAttachmentData:pdfData mimeType:@"application/pdf" fileName:self.pdfName];

Answer 1

根据我的代码更改 mime 类型，它会帮助你。

NSMutableData *pdfData = [NSMutableData data]; UIGraphicsBeginPDFContextToData(pdfData, bounds, nil);

然后在将来的某个时候，您需要将其传递pdfData给MFMailComposeViewController.

MFMailComposeViewController *vc = [[[MFMailComposeViewController alloc] init] autorelease]; [vc setSubject:@"my pdf"]; [vc addAttachmentData:pdfData mimeType:@"image/pdf" fileName:@"SomeFile.pdf"];
