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

在您的应用程序委托中添加这行代码:

Add this line of code on your application delegate:

目标-C:

[[UIApplication sharedApplication] setIdleTimerDisabled:YES];

斯威夫特 2:

UIApplication.sharedApplication().idleTimerDisabled = true

斯威夫特 3、4 和5:

Swift 3, 4 & 5:

UIApplication.shared.isIdleTimerDisabled = true
