如何在Swift中检测用户不活动? [英] How do I detect user inactivity in Swift?

问题描述

我需要实现一个空闲超时功能.为此，我只需要知道如何检测用户何时触摸屏幕(类似于Android中使用的onUserInteraction方法)即可.

I need to implement an Idle Time Out feature. To do that I simply need to know how to detect when the user touches the screen (something similar to onUserInteraction method used in Android).

那么我如何才能简单地发现用户何时与ViewController进行交互?

So how can I simply discover when the user interacts with the ViewController?

P.S:如果我问这是因为您在互联网上找不到任何好东西！

P.S: if I ask this it is because you can't find nothing good in the internet!

推荐答案

我的观点是，当用户触摸屏幕时，您需要捕获事件.方法:touchesBegan:withEvent

My take is that you need to catch the event when user touches a screen. Method: touchesBegan:withEvent

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

  for touch in touches {

  // get the time measurement
  // compare it to previous one for time difference


  }

}
