我正在为 iOS 7 开发一个应用程序并使用MFMailComposerViewController.

我已经尝试了一切，但dismissViewController:withAnimated没有工作。

viewController有时类在第一次使用方法显示时会自动调用委托presentViewCOntroller:withAnimated:completion。

我的应用程序是基于导航的，这就是为什么我认为问题也与之相关UINavigationController。

       -(void)sendMail{

if ([MFMailComposeViewController canSendMail]) {

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

    [picker setSubject:@"Hello from California!"];

    // Set up recipients
    NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"];
    NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
    NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"];

    [picker setToRecipients:toRecipients];
    [picker setCcRecipients:ccRecipients];
    [picker setBccRecipients:bccRecipients];



    // Fill out the email body text
    NSMutableString *emailBody =[NSMutableString stringWithString: @"<table border=1 align=\"center\"><tr><th>EventDate</th><th>EventDay</th><th>EventTime</th><th>Speaker</th><th>topic</th></tr>"];

    for (int i=0; i<5; i++) {
        NSString *eventDate=[NSString stringWithFormat:@"<tr><td>%@</td>",@"12/11"];
        NSString *eventDay=[NSString stringWithFormat:@"<td>%@</td>",@"Sunday"];
        NSString *eventTime=[NSString stringWithFormat:@"<td>%@</td>",@"12:10 pm"];
        NSString *eventSpeaker=[NSString stringWithFormat:@"<td>%@</td>",@"RajVeer"];
        NSString *eventTopic=[NSString stringWithFormat:@"<td>%@</td>",@"nano-technology"];
        NSString *dataString=[NSString stringWithFormat:@"%@%@%@%@%@</tr>",eventDate,eventDay,eventTime,eventSpeaker,eventTopic];
        [emailBody appendString:dataString];
    }
    NSString *lastTable=@"</table>";
    [emailBody appendString:lastTable];
    NSLog(@"%@",emailBody);
    [picker setMessageBody:emailBody isHTML:YES];

    [self presentViewController:picker animated:YES completion:NULL];


}

这应该可以解决问题：

#pragma mark MFMailComposeViewControllerDelegate

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

使用此代码呈现MFMailComposeViewController

[self presentViewController:mailComposerObject animated:YES completion:NULL];

解雇MFMailComposeViewController

#pragma mark - MFMailComposeViewControllerDelegate
-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult: (MFMailComposeResult)result error:(NSError*)error {
[self dismissViewControllerAnimated:YES completion:NULL];
}

iOS 6.0[self presentModalViewController:<#(UIViewController *)#> animated:<#(BOOL)#>]已弃用。
