如何在iPhone上禁用屏幕截图或自动对图像加水印? [英] How do I disable screenshots on iphone or automatically watermark image?

问题描述

可能重复:
是通知还是正在检测屏幕截图?

我想阻止从我创作的iphone应用程序分发图像.因此，我想阻止屏幕截图功能在我的应用程序运行时正常工作，或者如果用户确实进行了屏幕截图，则要自动为图像加水印.

I want to prevent the distribution of images from an iphone app that I've authored. As such, I would like to either prevent the screenshot feature from working whilst my app is running or, if the user does take a screenshot, to watermark the image automatically.

关于如何做到这一点的任何想法吗?

Any ideas as to how I could so this?

推荐答案

即使您可以做到，人们也总是可以做一些事情，例如用外接相机为iPhone拍照，这是您无法避免的.您防止屏幕截图的目的是什么?

Even if you could do that, people can always do things like photograph the iPhone with an external camera, which you have no way to guard against. What is your purpose of preventing screenshots?
