聆听iOS应用中的所有触摸事件 [英] Listen to all touch events in an iOS app

问题描述

是否可以以某种方式聆听并捕获应用中发生的所有触摸事件？

Is it possible to somehow listen to, and catch, all the touch events occurring in an app?

我正在开发的应用将用于展厅和信息亭，因此如果在给定的几分钟内没有收到触摸，我将回到应用程序的开始部分。一种屏幕保护功能，如果你愿意的话。我打算通过在后台运行一个计时器来实现这一点，每当应用程序中的某个地方发生触摸事件时，它将被重置并重新启动。但是如何听取触摸事件？任何想法或建议？

The app I'm currently developing will be used in showrooms and information kiosks and I would therefore like to revert to the start section of the app if no touches has been received for a given couple of minutes. A sort of screensaver functionality, if you will. I'm planning to implement this by having a timer running in the background, which should be reset and restarted every time a touch event occurs somewhere in the app. But how can I listen to the touch events? Any ideas or suggestions?

推荐答案

真的很容易。

你需要一个子类 UIApplication （让我们称之为 MyApplication ）。

You need a subclass of UIApplication (let's call it MyApplication).

您修改 main.m 以使用它：

return UIApplicationMain(argc, argv, @"MyApplication", @"MyApplicationDelegate");

你覆盖方法 [MyApplication sendEvent：] ：

- (void)sendEvent:(UIEvent*)event {
    //handle the event (you will probably just reset a timer)

    [super sendEvent:event];
}
