使用MFMailComposeViewController发送邮件，关闭模式视图控制器时获取"EXC_BAD_ACCESS" [英] Using MFMailComposeViewController to send a mail, get “EXC_BAD_ACCESS” when dismissing the modal view controller

问题描述

我正在使用MFMailComposeViewController从iPhone应用程序发送电子邮件.这可以正常工作，但是在发送或取消后，我需要关闭modalViewController.当我这样做时，我收到程序收到的信号:"EXC_BAD_ACCESS".这不是描述性的...请帮助！

I am sending an email from my iPhone app using MFMailComposeViewController. This works fine but after sending or canceling I need to dismiss the modalViewController. When I do this I get a Program received signal: "EXC_BAD_ACCESS". This is not very descriptive... Please help!!

这是用于创建邮件和modalViewController的代码

This is the code for creating the mail and the modalViewController

-(void)sendFavMail:(NSString *)body{

    MFMailComposeViewController* mailViewController = [[MFMailComposeViewController alloc] init];
    mailViewController.mailComposeDelegate = self;
    [mailViewController setSubject:@"Favorites List"];
    [mailViewController setMessageBody:body isHTML:YES]; 
    [self presentModalViewController:mailViewController animated:YES];
    [mailViewController release];   

}

这是委托的代码，关闭了modalviewcontroller:

And this is the code for the delegate, dismissing the modalviewcontroller:

- (void)mailComposeController:(MFMailComposeViewController*)controller  
          didFinishWithResult:(MFMailComposeResult)result 
                        error:(NSError*)error;
{
 switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Cancelled sending");
            break;
        case MFMailComposeResultSaved:
   NSLog(@"Message Saved");
            break;
        case MFMailComposeResultSent:
   NSLog(@"Message Sent");
            break;
        case MFMailComposeResultFailed:
   NSLog(@"Sending Failed");
            break;
        default:
   NSLog(@"Message not sent");
            break;
    } 
[self dismissModalViewControllerAnimated:YES];
}

感谢您的帮助！

推荐答案

该死，自己修复:-)

在发送/取消之前，我在邮件正文中释放了一个对象.我要做的就是声明此主体对象已自动释放.那你知道吗可以！

I released an object in the body of the message before sending/cancelling. What I did to fix it is to declare this body object autoreleased. And what do you know? IT WORKS!

就回答了我自己的问题...
