objective-c - UIActivityViewController 关闭 MailViewController

Question

我已尝试通过 UIActivityViewController 发送电子邮件，它工作正常，但邮件 View 在发送电子邮件后并未关闭。当用户按下取消按钮时，它也不会关闭。

我该怎么做才能解决这个问题？

这里是我用过的代码:

//conf share view
    NSString *textToShare = @"Teststring!";
    UIImage *imageToShare = fetchedImage;
    NSURL *urlToShare = [NSURL URLWithString:string_url];
    NSArray *activityItems = [[NSArray alloc]  initWithObjects:textToShare, imageToShare,urlToShare,nil];

    UIActivity *activity = [[UIActivity alloc] init];

    NSArray *applicationActivities = [[NSArray alloc] initWithObjects:activity, nil];
    UIActivityViewController *activityVC =
    [[UIActivityViewController alloc] initWithActivityItems:activityItems
                                      applicationActivities:applicationActivities];

    activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact,
        UIActivityTypePostToWeibo,
        UIActivityTypeCopyToPasteboard,
        UIActivityTypeSaveToCameraRoll,
        UIActivityTypePrint];

    [activityVC setCompletionHandler:^(NSString *activityType, BOOL completed) {
        NSLog(@"CompletionHandler was called!");
    }];

谢谢!

我有解决方案。你想在你的基础上展示 UIActivityViewController ，即你的最高或最后一个 View Controller 。就我而言，这有效:

[[[self parentViewController] parentViewController] presentViewController:activityViewController animated:YES completion:nil];

自己尝试调用 parentViewController 多少次，直到您访问最高层的 View Controller 。在我的简单 MasterView/DetailView 应用程序中，我不得不调用它两次。
