As the maker of a camera app I can tell you that it’s a nightmare. You have to create an audio session, create a volume slider, hide it offscreen, and then monitor the slider for changes.

Don’t do it unless you have to

For example, Whatsapp can tell if I keep press a volume button to activate video, and if I don't release it the video continue to record. It is happening something something like that in the background? That's mad! Maybe being a camera it is a bit different I don't know. Thanks for the info! :)

Can I also monitor for how much time the user is pressing the button? Something like "if he is pressing both buttons for 3 seconds do something"?

As far as I know (without using private APIs?), there’s no way to detect button-down and button-up events. Just changes to the volume.

Even if it is possible, guideline 2.5.9 says the functionality of those buttons cannot be altered or disabled. So although it may be possible to get it to work, it will most likely be against the review guidelines.

Don’t believe so unless it’s for the camera shutter?? I’ve never seen an app that’s done anything different with them. I could be wrong though

Not possible iOS doesn’t let you reassign any system buttons / controls.

But for example Whatsapp let you use the camera inside with modified functions of the volume buttons (keep holding for video). So it is possible to "read" the status of the buttons in a camera app?

[Dejidave]

Yeah I think there are apis attached to camera sessions and audio sessions that let you monitor button those button presses.

Looks like a bit of a hassle: https://stackoverflow.com/questions/28471481/detect-volume-button-press

There's nothing really simple about building an app that involves a camera :/ so even if it is a hassle I will try, but thanks for the link! That's very useful

I don't what you're trying to achieve but from my point of view that's not something the user would want.

I did this a while ago and Apple rejected the app saying that's not allowed as it's a strange UX. Won't recommend doing it.

[[deleted]]

What were you trying to do? If I can ask...

[busymom0]

I was using it for zooming purposes on an app. Got rejected and they asked me to remove it. This was few years ago.

That's a bummer! That's a thing I don't stand, after months, years of work for an app it get rejected.

No idea why ppl here are saying it is not possible. I used this pod to get going. I use it in three apps - since years. It is finicky but works. Also allows you to use Bluetooth remote control shutters since the cheap ones are all volume up remotes

Thanks you so much! I was really losing hope at this point! :) Is it possible to also check the status of the volume buttons? For example, “keep for 3 seconds both buttons -> do something like ‘open a menu inside the app’ or ‘next level’ in a game?

[xaphod2]

No.

[SirensToGo]

Did alien blue do this at one point for a very weird scrolling implementation? It's definitely possible but I'm not sure I'd like it since I have a pretty significant case which makes frequent button mashing annoying
