UIDocument交互控制器呈现选项菜单从栏按钮项不打开应用

Question

我使用UIDocumentInteractionController presentOptionsMenuFromBarButtonItem在Adobe Reader应用程序中打开PDF，用邮件发送并打印它。邮件和打印工作很好，但我无法打开任何其他应用程序。我尝试了presentOpenInMenuFromBarButtonItem和UIActivityViewController，但他们都不做我所需要的。

我试图用documentInteractionController: willBeginSendingToApplication: delegate打开Adobe Reader，但我找不到如何将pdf传递给应用程序。这是可能的吗?

如果没有，有没有另一种方法可以在adobereader应用程序中打开PDF，用邮件发送并打印它?

谢谢

通常我是这样做的:

   NSURL *documentsDirectoryPath = [NSURL fileURLWithPath:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject]];
    NSURL *URL =[documentsDirectoryPath URLByAppendingPathComponent:@"your pdf"];
    UIButton *button = (UIButton *)nil;
    self.documentInteractionController.delegate=self;
    if (URL) {
        // Initialize Document Interaction Controller
        self.documentInteractionController = [UIDocumentInteractionController interactionControllerWithURL:URL];
        // Configure Document Interaction Controller
        [self.documentInteractionController setDelegate:self];
        //preview
       [self.documentInteractionController presentPreviewAnimated:YES];
        // Present Open In Menu
        [self.documentInteractionController presentOpenInMenuFromRect:[button frame] inView:self.view animated:YES];
    }
