我可以在UIDocumentInteractionController视图上隐藏“操作"按钮吗? [英] Can I hide the Action button on the UIDocumentInteractionController view?

问题描述

我想知道是否可以隐藏UIDocumentInteractionController上的操作"按钮，以便用户实际上无法在其他应用程序中打开文档?

I wanted to know if I can hide the Action button on the UIDocumentInteractionController so a user couldn't actually open the document in another app?

推荐答案

我发现一些对我来说足够好用的东西:

I found something that works for me well enough:

- (BOOL)documentInteractionController:(UIDocumentInteractionController *)controller   canPerformAction:(SEL)action{
    return false;
}

它仍然显示按钮，但是显示的弹出窗口只有打印形式，但是打印按钮被禁用了.

It still shows the button but the popover that appears only has the print form but the print button is disabled.
