Is the proximity sensor a private api?

Question

Apple documents the proximity sensor here, so I would imagine it's a public api. I have heard otherwise and wanted to double check before submitting to the store.

Answer 1

It used to be the case that the proximity sensor was a private API, but after quite a bit of outcry, Apple made it a public API.

With the UIDevice API, you're able to query the proximity sensor for your needs, as documented in the link you've provided.
