我正在开发一个 iPad 应用程序，该应用程序创建一个 PDF，然后用户从该应用程序通过电子邮件发送。我已经能够成功设置电子邮件以附加 PDF，但我无法让 MFMailComposeViewController 关闭。我已经阅读了关于这个问题的其他几个问题，并试图模仿他们正在做的事情，但邮件撰写者仍然不会解雇。我需要在我的代码中进行哪些更改才能将其关闭？ 

- (IBAction)submitDailyReportButton:(id)sender {

MFMailComposeViewController *mail = [[MFMailComposeViewController alloc]init];
[mail setMailComposeDelegate:self];

if ([MFMailComposeViewController canSendMail]) {

    NSString *email =@"admin@domain.com";
    NSArray *emailArray = [[NSArray alloc]initWithObjects:email,nil];
    [mail setToRecipients:emailArray];

    [mail setSubject:@"Daily Report"];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

    NSString *newFilePath = [[paths objectAtIndex:0]stringByAppendingPathComponent:@"report.pdf"];

    NSData *pdfData = [NSData dataWithContentsOfFile:newFilePath];
    [mail addAttachmentData:pdfData mimeType:@"application/pdf" fileName:@"report.pdf"];
    NSString *body = @"Please review the attached daily report";
    [mail setMessageBody:body isHTML:NO];
    [mail setModalTransitionStyle:UIModalTransitionStyleCrossDissolve];
    [self presentViewController:mail animated:YES completion:nil];

}else{

    NSLog(@"Message cannot be sent");

}

}

您必须实现委托方法并在委托方法中关闭视图控制器。

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    [self dismissViewControllerAnimated:YES completion:nil];
}

旁注 - 如果您无法发送电子邮件，则无需创建邮件编写器。if在语句内移动分配。
