How to allow iPhone auto-lock while playing a video

Question

How can I allow iOS device to dim screen and auto-lock the device while playing a video with AVFoundation. Playing a video with AVPlayer disable screen auto-lock by default.

Answer 1

why you want screen to go idle while playing video? The real answer is it can't be done. Following are just work arounds with serious downsides.

The only method apple allows us to use is

[UIApplication sharedApplication].idleTimerDisabled

You can dim screen programmatically by using a UIView with color black and slowly changing it alpha property to create the illusion of screen going idle.
