iOS检测截图？ [英] iOS Detection of Screenshot?

问题描述

App Store上的应用 Snapchat 是一个可以让你的应用与他们分享自毁的照片。您只能查看X秒的照片。如果您在使用家庭电源键组合显示图片时尝试截取屏幕截图，它会告诉发件人您尝试截取屏幕截图。

The app Snapchat, on the App Store, is an app that lets you share pictures with a self-destruct on them. You can only view the pics for X seconds. If you attempt to take a screenshot while the picture is showing using the home-power key combo, it will tell the sender you tried to take a screenshot.

SDK可以让您检测到用户正在截取屏幕截图吗？我不知道这是可能的。

What part of the SDK lets you detect that the user is taking a screenshot? I did not know this was possible.

推荐答案

我找到了答案!!截屏会中断屏幕上的任何触摸。这就是为什么Snapchat需要持有才能看到图片。参考： http://tumblr.jeremyjohnstone.com/post/ 38503925370 / how-to-detect-screenshots-on-ios-like-snapchat

I found the answer!! Taking a screenshot interrupts any touches that are on the screen. This is why snapchat requires holding to see the picture. Reference: http://tumblr.jeremyjohnstone.com/post/38503925370/how-to-detect-screenshots-on-ios-like-snapchat
