保存PDF然後通過電子郵件發送

我想從一個URL保存PDF然後通過電子郵件發送。發件人似乎有它，但接收方不明白。保存PDF然後通過電子郵件發送

當我做NSString file的NSLog我得到/var/mobile/Applications/0ADE222E-6346-4C6C-8348-DA5327B980AA/Documents/myPDF.pdf

這似乎是它可以節省，但它不會發送。這是我下面的保存和發送

編輯

更新代碼

// This pdfURL is 0 bytes 
    NSData *pdfURL = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",webPage.urlString]]]; 

    //Store the Data locally as PDF File 
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentDirectory = [paths objectAtIndex:0]; 
    NSString *file = [documentDirectory stringByAppendingFormat:@"/myPDF.pdf"]; 

    [pdfURL writeToFile:file atomically:YES]; 

    //Sending the pdf 
    MFMailComposeViewController *composer = [[MFMailComposeViewController alloc] init]; 
    composer.mailComposeDelegate = self;   
    if ([MFMailComposeViewController canSendMail]){ 
     //Changed email for privacy issues 
     [composer setToRecipients:[NSArray arrayWithObjects:@"[email protected]", nil]]; 
     [composer setSubject:[NSString stringWithFormat:@"%@ email",titleText]]; 
     [composer setMessageBody:@"your custom body content" isHTML:NO]; 

     NSLog(@"pdf %@",file); 
     // This pdfData is 0 bytes 
     NSData *pdfData = [NSData dataWithContentsOfFile:file]; 

     [composer addAttachmentData:pdfData mimeType:@"application/pdf" fileName:@"myPDF.pdf"]; 

     [composer setModalTransitionStyle:UIModalTransitionStyleCrossDissolve]; 
     [self presentModalViewController:composer animated:YES];    
    }

你試過沒有「/」在你的addAttachmentData調用的文件名部分？ – trumpetlicks 2012-07-13 13:26:17

是的，我有。因爲之前我讀過的東西，我就在那裏。它不起作用，雖然 – BigT 2012-07-13 13:30:15

在你打電話給addAttachmentData之前，你能檢查你的PDF數據的大小，以確保有真正被讀取的東西嗎？ – trumpetlicks 2012-07-13 13:56:19

的問題是與webPage.urlString是空的代碼。此代碼的工作只需確保URL字符串不爲空：P

如果從網址的，它存儲在NSData的：

NSData *pdfData = [NSData dataWithContentsOfURL[NSURL URLWithString:@"URL Of Pdf"]];

然後附上郵寄
