UIDocumentInteractionController presentOptionsMenuFromBarButtonItem不打開應用程序

Question

我用UIDocumentInteractionController presentOptionsMenuFromBarButtonItem在Adobe Reader應用程序打開PDF，用郵件發送和打印。郵件和打印工作正常，但我無法打開任何其他應用程序。我試過presentOpenInMenuFromBarButtonItem和UIActivityViewController，但他們都沒有做我所需要的。

我試圖打開Adobe Reader時與documentInteractionController：willBeginSendingToApplication：委託，但我無法找到我怎麼能在PDF格式傳遞給應用程序。可能嗎？

如果沒有，是否有另一種方式在Adobe Reader應用程序打開PDF，用郵件發送和打印呢？

感謝

通常，這是我該怎麼辦：

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]; 

    }
