如何防止iOS设备上的显示变暗和关闭？ [英] How can I prevent the display on an iOS device from dimming and turning off?

问题描述

我正在深入iOS开发，正在构建自己的闹钟应用程序，以熟悉平台和SDK。我注意到应用程序商店中的一些闹钟应用程序会阻止屏幕变暗和/或在应用程序运行时关闭。这是如何实现的？

I'm diving into iOS development and am building my own alarm clock app to become familiar with platform and SDK. I've noticed some alarm clock apps in the app store keep the screen from dimming and/or turning off when their app is running. How is this implemented?

推荐答案

在您的应用程序代理上添加以下代码行：

Add this line of code on your application delegate:

Objective-C：

Objective-C:

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

Swift 2：

UIApplication.sharedApplication().idleTimerDisabled = true

Swift 3：

UIApplication.shared.isIdleTimerDisabled = true
