Mail composer上的DismissModaViewController无法正常工作

Question

当我完成屏幕截图并尝试在应用中通过电子邮件发送屏幕截图时，我遇到了问题。通常情况下，它在发送文本时效果很好，但一旦发送屏幕截图，无论是取消还是发送电子邮件，屏幕都不会消失。我可以知道这有什么问题吗？

这是我的代码。非常感谢你。

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

        if (buttonIndex == 0) {

        UIGraphicsBeginImageContext(self.view.frame.size);
        [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
        UIImage * image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();

        NSData * imageData = UIImageJPEGRepresentation(image, 1.0);

        if ( [MFMailComposeViewController canSendMail] ) {
            MFMailComposeViewController * mailComposer = [[[MFMailComposeViewController alloc] init] autorelease];
            mailComposer.delegate = self;
            [mailComposer addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"attachment.jpg"];

            /* Configure other settings */

            [self presentModalViewController:mailComposer animated:YES];
        }
    }
}
- (void)mailComposeController:(MFMailComposeViewController*)controller{
    [self dismissModalViewControllerAnimated:YES];
}

您需要实施的委托方法是mailComposeController:didFinishWithResult:error:，而不是mailComposeController:。有关详细信息，请参阅the documentation。
