iphone - MFMailComposeViewController 没有解雇

Question

我在 didSelectRowAtIndexPath 中调用了以下代码。问题是，当我点击取消按钮时，它提示保存草稿或丢弃。但是当我单击其中任何一个时， View 都不会消失。我在 iOS 5 之前的应用程序中使用了相同的代码，但它很好地解除了。有任何想法吗？我在界面中有 MFMailComposeViewController 委托(delegate)协议(protocol)。

    if (indexPath.row == 0)
    {
        if([MFMailComposeViewController canSendMail])
        {

            MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
            picker.mailComposeDelegate = self;

            [picker setSubject:@"Support"];

            NSArray *toRecipients = [NSArray arrayWithObject:@"contact@app.com"]; 

            [picker setToRecipients:toRecipients];

            NSString *emailBody = text;
            [picker setMessageBody:emailBody isHTML:NO];

            [self presentModalViewController:picker animated:YES];
        }
    }

使用:

dismissViewControllerAnimated:completion:

从 IOS 6.0 开始弃用:

将此方法添加到您的类中:

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