ios – 当InApp邮件命令被调用时，应用程序崩溃

当我通过UIActionSheetbutton填充消息撰写表时，我得到以下错误。 对不起，这些对我来说没有多大意义 – 还在学习:-)

任何人都可以帮忙吗？

这是问题的来源。

这是在日志中：

干杯杰夫

if ([MFMailComposeViewController canSendMail]) { MFMailComposeViewController *mailer = [[MFMailComposeViewController alloc] init]; mailer.mailComposeDelegate = self; NSString *subject = [[NSString alloc] initWithFormat:@"Multi Web - Sending %@.txt", _documentFile]; [mailer setSubject:subject]; // Attach an image to the email NSString *pathFile01 = [NSString stringWithFormat:_documentTXTPath]; NSURL *pdfURLFile01 = [NSURL URLWithString:pathFile01]; NSData *pdfDataFile01 = [NSData dataWithContentsOfURL:pdfURLFile01]; NSString *fileName = [[NSString alloc] initWithFormat:@"%@.txt", _documentFile]; [mailer addAttachmentData:pdfDataFile01 mimeType:@"application/txt" fileName:fileName]; NSString *emailBody = @"Hi,<br><br>Please find attached the note exported from Multi Web.<br/><br/>Thanks you for using the app.<br/><br/>Kind Regards,<br/>Multi Web Team."; [mailer setMessageBody:emailBody isHTML:YES]; [self presentModalViewController:mailer animated:YES]; } // Remove the mail view [self dismissModalViewControllerAnimated:YES]; - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { switch (result) { case MFMailComposeResultCancelled: NSLog(@"Mail cancelled: you cancelled the operation and no email message was queued."); break; case MFMailComposeResultSaved: NSLog(@"Mail saved: you saved the email message in the drafts folder."); break; case MFMailComposeResultSent: NSLog(@"Mail send: the email message is queued in the outbox.

}

Answer 1

正确的答案是删除

 [self dismissModalViewControllerAnimated:YES] 

在presentModalViewController方法之后。

您正在崩溃，因为您在提交模式视图控制器后立即closures模式视图控制器，并尝试在callback委托中再次解除模式视图控制器（已经解除分配）。
