How to prevent screen lock on my application with swift on IOS

Question

How can I prevent screen lock only when using Navigation. Waze has the option to do that, how can I do this in my App?

Answer 1

Use this:

Objective-C:

[[UIApplication sharedApplication] setIdleTimerDisabled: YES];

Swift (legacy):

UIApplication.sharedApplication().idleTimerDisabled = true

Swift 3/4:

UIApplication.shared.isIdleTimerDisabled = true

Make sure to import UIKit.

Here is the link to the documentation from apple.developer.com.

Answer 2

For Swift 3.0 here are two options depending on where you want to invoke the code:

Inside AppDelegate.swift:

application.idleTimerDisabled = true

Outside AppDelegate.swift:

UIApplication.shared().isIdleTimerDisabled = true

Answer 3

Swift 4

in AppDelegate.swift file, add the following line inside application function:

    application.isIdleTimerDisabled = true

Answer 4

You can use my little lib Insomnia (Swift 3, iOS 9+) - another nice feature is that you can prevent from sleeping only when charging.

The idleTimerDisabled soultion is okay but you have to remember to set it to false afterwards.

Answer 5

If you have more advanced case you can use our small project: ScreenSleepManager or if it's just about particular ViewControllers - use Insomnia as pointed earlier. Manual dealing with idleTimerDisabled almost always caused me some issues (like forgot to re-set to false or handle multiple (nested) modules trying to set it).
