SDL_HINT_IDLE_TIMER_DISABLED

A variable controlling whether the idle timer is disabled on iOS.

Header File

Defined in SDL_hints.h

Syntax

#define SDL_HINT_IDLE_TIMER_DISABLED "SDL_IOS_IDLE_TIMER_DISABLED"

Remarks

When an iOS app does not receive touches for some time, the screen is dimmed automatically. For games where the accelerometer is the only input this is problematic. This functionality can be disabled by setting this hint.

As of SDL 2.0.4, SDL_EnableScreenSaver() and SDL_DisableScreenSaver() accomplish the same thing on iOS. They should be preferred over this hint.

This variable can be set to the following values:

• "0": Enable idle timer
• "1": Disable idle timer
