Create a PDF to view email

I am super new to Objective-C, so please help me out.

I have a view with several labels and text views. I am trying to generate a PDF file for this page / view and connect to the email.

Firstly, I tried this approach, and it seems that the file has not been created or is not attached to the letter. Here are my codes:

NSMutableData *pdfData = [NSMutableData data];
UIGraphicsBeginPDFContextToData(pdfData, self.view.bounds, nil);
UIGraphicsBeginPDFPage();

[self.view drawRect:self.view.bounds];

UIGraphicsEndPDFContext();

MFMailComposeViewController *mailComposer = [[[MFMailComposeViewController alloc] init] autorelease];
mailComposer.mailComposeDelegate = self;



[pdfData writeToFile:file atomically:YES];



[mailComposer addAttachmentData:pdfData mimeType:@"application/pdf" fileName:file];

[self presentModalViewController:mailComposer animated:YES];

And since this did not work, I tried a different approach, first creating a PDF and then attaching it to the email. Then I saw that the PDF file was created in this directory, but it is empty !!!

Here are my revised codes:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *file = [documentsDirectory stringByAppendingFormat:@"/tempFile.pdf"];

UIGraphicsBeginPDFContextToFile(file, self.view.bounds, nil);
UIGraphicsBeginPDFPage();

[self.view drawRect:self.view.bounds];

UIGraphicsEndPDFContext();

MFMailComposeViewController *mailComposer = [[[MFMailComposeViewController alloc] init] autorelease];
mailComposer.mailComposeDelegate = self;



[pdfData writeToFile:file atomically:YES];



[mailComposer addAttachmentData:pdfData mimeType:@"application/pdf" fileName:file];


[self presentModalViewController:mailComposer animated:YES];
  • Can you please help me successfully create a PDF file from the view and then attach it to the letter?

I tried several ways, but I can’t understand what I am doing wrong. Many thanks!
