MFMailComposeViewController不会在iOS 6

问题描述:

解雇在iOS 6中所提出的MFMailComposeViewController不会解散,如果用户试图发送第二封邮件......MFMailComposeViewController不会在iOS 6

一切完美的作品首次面世,并发送电子邮件。但是,如果再次选择电子邮件选项,MFMailComposeViewController不会取消取消。

这里是我是如何实现它:

- (IBAction)buttonEmailClick:(id)sender { 
    if (![MFMailComposeViewController canSendMail]) { 
     UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Can't send" message:@"This device is unable to send emails." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
     [alert show]; 
     return; 
    } 
    NSDictionary *contactsInfo = [self contactsInfoFromPlistNamed:kConfigPlistName]; 
    [mailComposeViewController setToRecipients:[NSArray arrayWithObject:[contactsInfo objectForKey:@"email"]]]; 
    //[mailComposeViewController setSubject:kEmailDefaultSubject]; 
    //[mailComposeViewController setMessageBody:text isHTML:NO]; 
    [self presentModalViewController:mailComposeViewController animated:YES]; 
} 

,然后这样的:

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { 
    UIAlertView *alert = nil; 
    if (result == MFMailComposeResultSent) { 
     alert = [[UIAlertView alloc] initWithTitle:@"Sent" message:@"Your email was sent." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    } 
    else if (result == MFMailComposeResultFailed) { 
     alert = [[UIAlertView alloc] initWithTitle:@"Failed" message:@"An error occured and your email was not sent." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    } 

    [alert show]; 
    [self dismissModalViewControllerAnimated:YES]; 
} 

它工作正常,在iOS 5中,但不是在iOS的6我曾尝试与非不赞成的方法代替iOS 6,但它不起作用。

您是否尝试过在每次发送邮件时都创建一个新的MFMailComposeViewController?我不确定你是否应该重复使用它。

应该叫我认为这就是问题所在!一旦电子邮件发送并且用户被带回到呈现视图控制器,是否有方法创建新的MFMailComposeViewController?我非常感谢快速回复和帮助。 – user2175392 2013-03-15 20:19:37

是的,我的建议是在调用'setToRecipients'之前放置'mailComposeViewController = [[MFMailComposeViewController alloc] init];'。 – 2013-03-15 20:21:11

太棒了。谢谢!我会尝试第二次回到Mac。 – user2175392 2013-03-15 20:40:55

你可以试试这个:

MFMailComposeViewController * composer = [[MFMailComposeViewController alloc] init]; 
composer.delegate = self; 

- (空)mailComposeController:didFinishWithResult:错误:如果您分配类委托
