我有一个 UIActivityViewController 不会关闭 iPad 上的邮件对话框。该代码是来自 Apple 示例的标准代码，并且在 iPhone 上运行良好。

   NSString* someText = [NSString stringWithFormat:@"%@ Is really cool, sent from Element Story. en.wikipedia.info/wiki/%@",
                          [_detailItem description], [_detailItem description]];

   ActivityViewCustomProvider *customProvider =
    [[ActivityViewCustomProvider alloc]init];

    NSArray *items = [NSArray arrayWithObjects:customProvider,imageView.image,someText, nil];

    //ActivityViewCustomActivity *ca = [[ActivityViewCustomActivity alloc]init];


    // ...or whatever pieces of data you want to share.
    UIActivityViewController *activityVC =
    [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:nil];
                                      //applicationActivities:[NSArray arrayWithObject:ca]];

activityVC.excludedActivityTypes = @[UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard];
    [self presentViewController:activityVC animated:YES completion:^{}];

我假设您正在从 splitviewcontroller 显示此内容，这也是我遇到的问题。本质上，您需要从主视图中呈现 UIActivityViewController。

所以而不是

[self presentViewController:activityVC animated:YES completion:nil];

就像是：

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

不幸的是，它看起来不太好，因为它会在整个视图中显示选项，而不仅仅是在导航端或细节端的上下文中，但它会起作用。
