问题
Writing the part of the app that allows the user to generate a pdf and send it. Seems to be working fine. The sent PDF opens fine on the MAC, but on the iPhone it just keeps loading and never opens. Created a pdf document with the help of Ray Wenderlich Tutorial and sent it out through a modal view controller with a instance of an MFMailComposeViewController. WTF am i doing wrong.
Update: The PDF also opens fine on the Ipad. Could the problem be somewhere in the code for creating the PDF? Also it is a little unclear to me if I am actually creating a PDF that is persisting and then getting replaced after each new version of the same named file or am I somehow tricking the compiler into thinking a doc is getting stored so I can send it out with the least code possible.
Any thoughts on this would be appreciated.
check out the code:
if ([MFMailComposeViewController canSendMail])
{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:@"mail test"];
NSString* fileName = @"Invoice.PDF";
NSArray *arrayPaths =
NSSearchPathForDirectoriesInDomains(
NSDocumentDirectory,
NSUserDomainMask,
YES);
NSString *path = [arrayPaths objectAtIndex:0];
NSString* pdfFileName = [path stringByAppendingPathComponent:fileName];
NSData *myData = [NSData dataWithContentsOfFile:pdfFileName];
[picker addAttachmentData:myData mimeType:@"application/pdf" fileName:@"the PDF"];
[self presentModalViewController:picker animated:YES];
}
回答1:
try this way
[picker addAttachmentData:myData mimeType:@"application/pdf" fileName:@"thePDF.pdf"];
BTW, if you are generating the PDF content just before sending it, you don't need to save to a real pdf file, just send the PDF data
