iphone mailcomposer

Question

我有我的tabbar，我可以通过下面的代码隐藏此标签栏但是当点击iphone邮件编辑器的cancle没有返回到默认屏幕时，请指导我该怎么做

-(void)displayComposerSheet
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    [picker setSubject:@""];



    // Set up recipients
    NSArray *toRecipients = [NSArray arrayWithObject:@""];
    NSString *emailBody = @"";
    [picker setMessageBody:emailBody isHTML:NO];

    //[self presentModalViewController:picker animated:YES];
    UIViewController *xyz=(UIViewController*)[myMarketsVicAppDelegate getMainTabbarRef];
    [xyz presentModalViewController:picker animated:YES];

    [picker release];
}


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

Answer 1

您必须实施以下代理。

1. UINavigationControllerDelegate
2. MFMailComposeViewControllerDelegate，

喜欢这个

<MFMailComposeViewControllerDelegate,UINavigationControllerDelegate>。

上面可能是一个问题，因为 - 如果你还没有实现上面的委托，它会给你编译时警告但是它会执行。
