IOS5中pdf添加到Email中

添加一个pdf到Email中,操作如下:

-(IBAction)mailPDF:(id)sender{
    MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
    controller.mailComposeDelegate = self;
    NSLog(@"myData is %@",myData);
    [controller setSubject:@"Geselecteerde favorieten van Genk on Stage"];
    [controller setMessageBody:@"<p>Hallo muziekliefhebber <br /> In bijlage vind je jouw favorieten. Volg en praat met ons mee op facebook.com/genkonstage of @genkonstage!<br /> Veel plezier op Genk on stage! </p>" isHTML:YES];
    if (controller){
        [self presentModalViewController:controller animated:YES];
        [controller addAttachmentData:myData mimeType:@"application/pdf" fileName:@"favorite.pdf"];
    }else{
        NSLog(@"nothing to show");
    }
}

设置数据:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"favorite.pdf"];
 myData = [NSData dataWithContentsOfFile: filePath];

在看log mydata(就是pdf)时,显示并不为空。浏览模拟器“我的文档”也能看见pdf。
请指教为什么我的pdf无法添加到Email中?

在ios6中没问题,只有在ios5中有问题。

你先显示了view controller,然后才将文件作为附件添加,因此修改一下操作顺序就好。

这行代码:

[self presentModalViewController:controller animated:YES];

[controller addAttachmentData:myData mimeType:@"application/pdf" fileName:@"favorite.pdf"];

修改为:

[controller addAttachmentData:myData mimeType:@"application/pdf" fileName:@"favorite.pdf"];

[self presentModalViewController:controller animated:YES];
