    // We must always check whether the current device is configured for sending emails
    if ([mailClass canSendMail]) {

        NSLog(@"cant send mail");
    }
} else {

    NSLog(@"class not instantiated");

}
}

なぜこれが起こっているのか誰にもわかりますか？

コード内から送信イベントをキャプチャする必要があることに気付きました

そのような

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