iOS-如果addAttachmentData:，则MFMailComposerViewController无法取消

Question

我的MFMailComposer代码：

MFMailComposeViewController *mailViewController = [[MFMailComposeViewController alloc] init];
[mailViewController setDelegate:self];
[mailViewController setSubject:@"subject"];
[mailViewController setToRecipients:[NSArray arrayWithObject:@"[e-mail]"]];
[mailViewController setMessageBody:@"body" isHTML:NO];
for (int i = 0; i < self.imagesData.count; i++)
{
    NSDateFormatter *dateFormatter=[[NSDateFormatter alloc] init];
    [dateFormatter setDateFormat:@"yyyy-MM-dd-HH-mm-ss-SSSS"];
    [mailViewController addAttachmentData:[self.imagesData objectAtIndex:i] mimeType:[self contentTypeForImageData:[self.imagesData objectAtIndex:i]] fileName:[NSString stringWithFormat:@"portfolio_%@_%d", [dateFormatter stringFromDate:[NSDate date]], i]];
}
[self presentViewController:mailViewController animated:YES completion:nil];

有了这段代码，我会按取消并删除草稿，但什么也没发生，MFMailComposerViewController不会关闭。

我已经添加了代表：

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error{
if(error) NSLog(@"ERROR - mailComposeController: %@", [error localizedDescription]);
if (result == MFMailComposeResultSent)
{
    NSLog(@"It's away!");
}
[[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
[self dismissViewControllerAnimated:YES completion:nil];}

我错过了什么？

好的，我找到了答案。我很愚蠢。

我使用了setDelegate而不是setMailComposeDelegate
