我正在打开电子邮件表以发送文件。它工作得很好，只是我不能回到我的应用程序。

当我点击取消按钮时，它会询问是否删除或保存草稿，并留在那里。它不会返回应用程序页面。

代码：

//send email log-------------------------
    NSLog(@"mail");
    [[CCDirector sharedDirector] pause];

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

    //Fill in the email as you see fit
    NSArray *toRecipients = [NSArray arrayWithObject:@"name@gmail.com"]; 
    [picker setToRecipients:toRecipients];


    NSArray *paths2 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *dataPath = [[paths2 objectAtIndex:0] stringByAppendingPathComponent:@"Test.txt"];
    NSData *data = [NSData dataWithContentsOfFile:dataPath];
    [picker addAttachmentData:data mimeType:@"text/txt" fileName:@"Test.txt"];

    NSString *emailBody = @"Test   ";
    [picker setMessageBody:emailBody isHTML:NO];
    [picker setSubject:@"hardware test ##   "];

    //display the view
    [[[CCDirector sharedDirector] openGLView] addSubview:picker.view];
    [[CCDirector sharedDirector] stopAnimation];

编辑：

我在这里添加了答案中建议的函数，当我点击取消时，他调用了该函数，但它保留在该表中。我不得不说我使用的是 cclayer (cocos2d)，所以该层定义为：

@interface HelloWorldLayer : CCLayer< MFMailComposeViewControllerDelegate>

还有什么建议吗？

非常感谢。

您必须实现委托方法

- (void)mailComposeController:(MFMailComposeViewController*)controller
        didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error

并在那里关闭视图控制器：

[picker dismissViewControllerAnimated:YES completion:^{}];

更新：

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