iphone - 如何在 iOS 应用程序中使用电子邮件？

Question

请告诉我如何发送电子邮件？

这意味着当用户单击我想要从应用程序检索一些数据并将其发送到技术助理的邮件 ID 时，我有一个 uibutton。有没有简单的方法可以做到这一点？

您必须使用 MFMailComposeViewController 类和 MFMailComposeViewControllerDelegate 协议(protocol)，

PeyloW 在他的回答 here 中为此提供了以下代码:

First to send a message:

MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"My Subject"];
[controller setMessageBody:@"Hello there." isHTML:NO]; 
[self presentModalViewController:controller animated:YES];
[controller release];

Then the user does the work and you get the delegate callback in time:

- (void)mailComposeController:(MFMailComposeViewController*)controller  
          didFinishWithResult:(MFMailComposeResult)result 
                        error:(NSError*)error;
{
  if (result == MFMailComposeResultSent) {
    NSLog(@"It's away!");
  }
  [self dismissModalViewControllerAnimated:YES];
}
